Soil and Water Assessment Tool User’s Manual Version 2000S.L.Neitsch, J.G.Arnold, J.R.Kiniry, R.Srinivasan, J.R.Williams, 2002Chapter 1 overview1.1 流域结构 WATERSHED CONFIGURATION✧子流域-无数量限制的HRUs(每个子流域至少有1个)-一个水塘(可选)-一块湿地(可选)✧支流/干流段(每个子流域一个)✧干流河网滞留水(围坝拦截部分)(可选)✧点源(可选)1.1.1子流域(subbasins)子流域是流域划分的第一级水平,其在流域拥有地理位置并且在空间上与其他子流域相连接。

1.1.2 水文响应单元(HRU)HRUs是子流域拥有特定土地利用/管理/土壤属性的部分,其为离散于整个子流域同一土地利用/管理/土壤属性的集合,且假定不同HRU相互之间没有干扰。

HRUs的优势在于其能提高子流域负荷预测的精度。

一般情况下,一个子流域每会有1-10个HRUs。

为了能在一个数据集组合更多的多样化信息,一般要求生成多个具有合适数量HRUs的子流域而不是少量拥有大量HRUs的子流域。

1.1.3主河道(Reach/Main Channels)水流路线、沉积物和其他经过河段的物质在theoretical documentation section7中有描述。

1.1.4 支流(Tributary Channels)辅助性水流渠道用来区分子流域产生的地表径流输入的渠系化水流。

附属水道的输入用来计算子流域径流产生到汇集的时间以及径流汇集到主河道的输移损失。

辅助性水道输入定义了子流域最长达水流路经。

对某些子流域而言,主河道可能是最长的水流路经,如果这样,辅助性水流渠道的长度就和主河道一样。

在其他子流域,辅助性河道的长度和主河道是不同的。

1.1.5池塘、湿地和水库(Ponds/Wetlands/Reservoirs)两类水体(池塘/湿地)在每个子流域都会有定义。

ArcSWAT建模与SWAT-CUP率定、验证中遇到的问题与解决方案

ArcSWAT建模与SWAT-CUP率定、验证中遇到的问题与解决方案

将ArcSWAT建模与SWAT-CUP率定、验证过程中的一些问题和自己最终的解决方案梳理如下,以期对新手有所指导。

1、DEM、土地利用类型、土壤数据必须投影相通,且为面积投影。

土壤数据可以用HWSD1.2,气象数据可以用CMADS1.1。

可以预先将cfsr_world数据库导入数据库文件,模拟站点就选cfsr_world。

可以整体使用CMADS,导入气象数据时,将CMADS1.1的站点文件直接导入(气象站点和全部气象数据文件放入同一个文件夹中),模型会自动筛选所需气象站点。

2、在输入气候数据时显示日期语法错误可能是电脑日期格式问题,更改电脑时间设置格式为yyyy/m/d即可。

3、ArcGIS10.2和ArcGIS10.4破解相对比较完全,推荐使用这两个版本建模(最好是ArcGIS10.2版),其他版本可能会增加出错概率。

4、运行模型时,关闭杀毒软件和安全卫士。

5、ArcSWAT和SWAT-CUP运行时,涉及到读写权限,建议运行软件时,使用管理员权限,所在文件夹要获得完全权限。

6、导出swat模拟结果至mdb数据库时,如果没有涉及到水库模拟的话,不要选择rsv文件,会报错。

7、ArcSWAT和SWAT-CUP运行时,涉及到读写权限,建议运行软件时,使用管理员权限,所在文件夹要获得完全权限。

8、SWAT-CUP安装结束后,将ArcSWAT安装文件中的swat20**拷贝进SWAT-CUP安装文件夹中对应的文件夹中(\SWAT-CUP\ExternalData\SourceData\SWAT20**)。

9、新建的SUFI2文件建议放在D盘根目录下。

10、SWAT-CUP中NS为负值,可能是模拟结果与实测数据相差太大所致。

11、SWAT-CUP运行时,部分模拟出错可能与部分参数给定范围过大、导致越界有关,缩小参数范围即可以解决。

12、参数敏感性分析时,参数改变方式可以参考相关文献,ArcSWAT中的手动率定助手中,参数都有缺省改变方式,可以参考设置。

arcswat_version201210_218_releasenotes

ArcSWAT 2012.10_2.18 Release NotesUpdated 9/9/15AcrcGIS Compatibility:ArcSWAT 2012.10_2.18 is compatible with ArcGIS 10.2.2, build 3552.SWAT2012.exe Version:The SWAT2012.exe Revision 637 is packaged with ArcSWAT 2012.10_2.18.Changes from Version 2012.10_2.17:IMPORTANT: Older SWAT projects created prior to the current ArcSWAT version should run the new “Database Update” utility found under the “Write Input Tables” menu. This utility will update the tables in your SWAT project database (e.g., “gw”, “hru”) to make sure all the correct columns are in the table and assign default values for the new columns. The utility will also copy new parameter “range” tables from the current SWAT2012.mdb distributed with the ArcSWAT to the SWAT2012.mdb database associated with your current ArcSWAT project. You should select all tables when you run the database update.1.tblOutputVars: In the previous ArcSWAT version, the “Database Update” utility was not copyingthe new “tblOutputVars” table from the newly installed “SWAT2012.mdb” database into previously created projects. This has been fixed now.2.There had been some reports of output files (such as output.rch) not getting imported to the SWAToutput database correctly when the user selected output variables option was chosen. Some database checks have been added to help prevent this error.3.The new “ElevationBand” table is now automatically created when running “Write SWAT InputTables”. This addresses an error that could occur if a user did not run the “Database Update” utility prior to writing the SWAT input tables.Changes from Version 2012.10_2.16:IMPORTANT: Older SWAT projects created prior to the current ArcSWAT version should run the new “Database Update” utility found under the “Write Input Tables” menu. This utility will update the tables in your SWAT project database (e.g., “gw”, “hru”) to make sure all the correct columns are in the table and assign default values for the new columns. The utility will also copy new parameter “range” tables from the current SWAT2012.mdb distributed with the ArcSWAT to the SWAT2012.mdb database associated with your current ArcSWAT project. You should select all tables when you run the database update.4.Automatic elevation band delineation: Inputs to allow automatic delineation of elevation bands havebeen added to the HRU Definition interface as a new tab to the form. Users can now specify theminimum difference between subbasin minimum elevation and maximum elevation in order forbands to be delineated, as well as the number of elevation bands for those subbasins meeting thecriteria. Elevation bands are delineated such that each band has equal area.5.Subbasin elevation band re-calculations in “SUB” file edit: When editing subbasin parameters, userscan now change the number of elevation bands for the subbasin, and the interface will automatically determine the elevation band elevations and fractions. For this to be functional, the SWAT modelwill need to have had basin delineation occur with ArcSWAT Version 2012.10_1.17.6.From the “Run SWAT’ interface, users can now choose which RCH, SUB, and HRU parameterswill be printed in the output files.7.Additional error checking was added to soils database code to look for missing soils.8.The CROP table in the SWAT2012.mdb database was updated with new crops9.When using the US STATSGO soils database, the selection of which component to choose wasmodified from the old method of choosing the first SEQN value, to now choose the component with the maximum percentage of the map unit.10.Units for rooting depth printed in the .SOL file were corrected.11.The default operation schedules in the “OpSchedules” table in the SWAT2012.mdb database cannow be date based in addition to heat unit based.12.A new definition for the iEvent variable was incorporated.13.The input file formatting of observed reservoir outflows was modified to be able to accommodatelarger values.14.A new HRU delineation method based on a user’s target number of HRUs in the watershed wasadded.15.The Cropland Data Layer (CDL) lookup table was added into the SWAT2012.mdb database, and asan option in the Land Use analysis tab during land use/soils/slope overlay.16.A bug in how the output.mgt file was importing into the SwatOutput.mdb database was fixed.17.The required location for custom SWAT executables (swatUser.exe) was changed to be the project’sTxtInOut folder. This allows different custom SWAT executables to be used with different projects. Changes from Version 2012.10_2.15:1. A bug was introduced in version 2012.10_2.15 that occurred during watershed delineation. The bugoccurred when users added their own outlet points to the delineation, beyond the automaticallygenerated outlets. The result was most often an error message that prevented delineation fromcontinuing to completion. Version 2012.10_2.16 corrects this problem.Changes from Version 2012.10_2.14:IMPORTANT: Older SWAT projects created prior to the current ArcSWAT version should run the new “Database Update” utility found under the “Write Input Tables” menu. This utility will update the tables in your SWAT project database (e.g., “gw”, “hru”) to make sure all the correct columns are in the table and assign default values for the new columns. The utility will also copy new parameter “range” tables from the current SWAT2012.mdb distributed with the ArcSWAT to the SWAT2012.mdb databaseassociated with your current ArcSWAT project. You should select all tables when you run the database update.2.Updated the CROP table to include several new crops in the SWAT2012 database.3.Modified writing of atmo.atm file to only write the file if average annual value option is chosen.Users can supply their own atmo.atm monthly values by choosing an IATMO value of “1”. Inaddition, the same deposition values specified in the .BSN file are written as one line for everysubbasin in the watershed.4.The DEM, Land use, and soils raster datasets can now be read in from a file geodatabase.5.The header line in the .RES files was modified to be compatible with SWAT-CUP.6.The handling of split sub-landuses during HRU delineation has been modified for the case exemptland uses are specified. In this version, if a parent land use is specified as being “exempt” from theland use threshold, then all sub-land uses will also be exempt.7.New parameters in the HRU table and .hru files have been added to the interface.8.New parameters in the BSN table and .bsn file have been added to the interface.9.The SWAT executable has been updated to version 627.Changes from Version 2012.10_1.13:1.Corrected a bug in the printing of “Residue Management” and “Generic Conservation Practice”operations in the .OPS files.2.Added error checking to the writing of all SWAT ascii input files that specifies which subbasin orHRU has an error that causes the printing error.3.Added new code to automatically print the .SUB files in the .OPS files get re-written.4.Fixed some issues associated with the new “Database Update” functionality available from the“Write Input Tables” menu to ensure cleaner operation. This should fix issues associated with“PR_W1” and “PR_W2” in the WGN table interfaces.5.Modified the printing of the “CH_EQN” parameter in the “.rte” file to print as an integer forSWAT-CUP compatibility.6.Modified the option of applying point sources to every subbasin. Due to occasional issues withapplying this option for user defined streams, the point source geographic locations are now set to be the “label point” of the subbasin. The point source location will no longer appear coincident with a reach. This has no impact on the model simulation.7.Update the reading of “output.pot” to be compatible with latest output format from SWAT.exe. Filecan now be read into the SWATOutput.mdb database.8.Updated the version of SWAT-Check to most recent (2/26/14) version.9.Updated the version of the swat2012.exe to Rev. 622.Changes from Version 2012.10_0.12:1.Added a new item to the “Write Input Tables” menu. The new item, “Database Update”, launchesan interface that allows the user to select ArcSWAT tables to update to the database structurecompatible with the current ArcSWAT version. Important: Running this new utility is necessarywhen using ArcSWAT for a project that was created with an earlier version of ArcSWAT.Otherwise, interface errors or crashes are more likely to occur. It is best to select all tables to getchecked for updates.2.Fixed a bug in the User Weather stations editing interface that occurred when updating values forthe PR_W1 and PR_W2 parameters.3.Updated some “ArcAPEX” message box text to say “ArcSWAT”.4.Fixed a bug related to the printing of observed reservoir outflow time series that caused errormessages to occur when the starting date of the simulation was earlier than the starting date of the reservoir operation.5.Fixed a bug in the “res” table to correctly set the value of the “RES_SUB” parameter to be equal tothe subbasin. This bug did not result in any errors in the printing of .res files or simulations.6.Updated default and range values for some PND and GW table parameters.Changes from Version 2012.10_0.11:7.Updated the .GW interface to add new parameters.8.Updated printing of PCPmm in the .WGN files to handle values 1000 and greater.9.Fixed a bug in the editing of Manning’s overland flow values in crop database.10.Modified the land use change functionality to make subsequent land use changes cumulative on theland use changes specified earlier in the model run period.11.Fixed a bug in the assignment of lat and long to the point sources in the MonitoringPoint featureclass. The values were reversed when running user defined watersheds and streams and when theuser chooses to add a point source to each watershed.Changes from Version 2012.10_0.10:1.Modified the point source/inlet editing interface regarding how the type of point source/inlet(constant, daily, etc.) is checked, reducing the chance for errors to be encountered.2.Modified the header line in the .hru files to print “Slope:” instead of “Slope”. This was necessary forSWAT-CUP compliance.3.Modified the ranges for PLAPS and TLAPS in the “subrng” table in the SWAT2012.mdb database.4.Fixed the printing of the pcp.pcp and tmp.tmp files so that lat, lon, and elevation are printedcorrectly.5.Fixed a problem with the .sub file editing interface regarding the flag to use subbasin specific .snofiles. There were situations where this flag (SUBSNOW in the sub table) was being unintentionally set back to a value of “0”.Changes from Version 2012.10_0.9:6.Fixed an issue introduced in 2012.10_0.9 with the delineation of HRUs when the split HRUs optionwas used AND the new split HRU land classes were not already part of the original land use class.The split HRUs were not getting created correctly in 2012.10_0.9.7.Updated the WGN tables in the “ArcSWAT_WeatherDatabase.mdb” database. Problems with dewpoint temperature and half hour rainfall intensity value identified in the previous version of thedatabase have been fixed.Changes from Version 2012.10_0.8:8.Calculation of closest weather stations to each subbasin: A bug was fixed that could occur if thedistance from the weather station to the subbasin “center” was equal to 0. In these situations, thesecond closest station was selected. This issues had been corrected.9.Assignment of subbasin Lat/Long: The subbasin Lat and Long attributes (in watershed featureclass) were modified so that they are first calculated as the centroid of the subbasin. If the centroid falls outside the subbasin boundary, then the subbasin lat/long is calculated as the “label point” of the subbasin. The “label point” will always be within the subbasin boundary.10.RunSWAT: When the SWAT model is run, the “swat2012.exe” file is now deleted from theTxtInOut folder once the process finishes (change made for SWAT-CUP).11.CHLA_SUBCO: The min, max, and default values for this parameter were modified in theswat2012.mdb database.12.Watershed Delineation: Parts of the watershed delineation code were modified to help improvestability, particularly during stream delineation.13.Atmo.Atm: The writing of this file was corrected. Values for atmospheric deposition are now storedin the BSN tables and are editable through the bsn edit interface.14.Reading weather station location files: Problems associated with reading in text files of weatherstation location (found on some computers) was fixed.15.HRU Splitting: The process of splitting HRUs into sub-HRUs was found to potentially result induplicate HRUs (same subbasin, land use, soil, slope). The HRU splitting process was re-written to correct this potential problem.16.Measured PET File: The documentation on how to handle and format measured PET data wascorrected in the ArcSWAT documentation.17.Irrigation Sources: The use of reservoirs as irrigation sources was not being handled correctly. Oneof the problems was in associated printing of the .mgt files. Another problem was in the sorting of the irrigation sources in the MGT interface. These issues have been corrected.Changes from Version 2012.10_0.7:1.The default subbasin channel slope (CH_S1) had been set to the mean subbasin slope (the SLO1field in the Watershed feature class). The more appropriate value to use is the longest flow pathslope (the CSL field in the Watershed feature class). The default value for the CH_S1 value is now set to the longest flow path slope.2.In the .hru files, the parameter CFDEC was only being printed out 1 digit to the right of thedecimal. The precision has been increased to 3 digits to the right of the decimal.3.In the .bsn file, the parameter PC_BSN was only being printed out 2 digit to the right of thedecimal. The precision has been increased to 3 digits to the right of the decimal.4.In the BSN edit interface, the CN_FROZ was assigned to either “inactive” or “active”. Now, theparameter takes a specific value (default = 0 .000862) and prints that to the .bsn file.ArcSWAT 2012 Version Notes:ArcSWAT for SWAT 2012 includes several changes from ArcSWAT for SWAT 2009. Some of the more significant updates include the following:1.SSURGO Soils Integration: Integration with SSURGO-based spatial soils dataset and hasbeen included in the Land Use/Soils/Slope Overlay process. In addition, a nationaldatabase of SSURGO soils attributes has been developed. This database can be downloadedfrom the SWAT web site at: /software/arcswat/ .2.Expanded Weather Database: An expanded monthly weather database for the United Statesis now included with the ArcSWAT install package. This database,“ArcSWAT_WeatherDatabase.mdb”, contains monthly weather statistics (for the SWATweather generator) for over 18,000 stations. There are four different time periodsrepresented, allowing for comparative analysis suitable for climate change studies. Thesetime periods include, 1960 – 1990, 1970-2000, 1980-2010, and 1960-2010.3.Updated ArcSWAT Table Management: The interface for writing of default SWAT inputtables has been re-designed. In addition to the change to the user interface, the back-endprocessing which creates the default tables is now conducted without the use of ESRIArcObjects software. This has allowed a significant expansion in the functionality of theArcSWAT companion software, SWATEditor. SWATEditor can now process and theweather data and generate all input tables, no longer requiring ArcGIS for this purpose.ers can now change the weather inputs multiple times without needing to re-write and/oredit the SWAT input tables before re-running the model. Note: ArcSWAT 2012 no longersupports dBase format weather input files. Only text files are allowed. See that ArcSWAT2012 documentation for format requirements.5.New DRAINMOD Sub-Surface Drainage: New options for simulating sub-surfacedrainage have been added to SWAT and the ArcSWAT interface. The new DRAINMODdrainage option follows is accessible through the HRU table editing interface.6.Urban BMPs: Four new urban BMPS can now be simulated with SWAT 2012 and can beparameterized using the ArcSWAT interface. The new BMPs include Detention Ponds,Wet Ponds, Retention/Irrigation Basins, and Sedimentation/Filtration Basins. These BMPscan be accessed from the PND table editing interface.7.Expanded Output Files: A significantly larger number of SWAT output files can now beread into the SWATOutput database. There are now 15 different SWAT output files thatcan be imported for analysis.8.SwatCheck: SWAT model output in the output.std file can now be analyzed for possibleerrors or unreasonable values through the SwatCheck program, accessed directly fromArcSWAT.9.Updates to the SWAT 2012 model executable: The SWAT2012 model executable includessome changes to the SWAT2009 model executable. In some cases, results obtained from the SWAT2012 model will not be the same as the SWAT2009 model.。

Arc swat安装步骤

Arc swat安装步骤

Soil and Water Assessment Tool (SWAT)模型的安装Soil and Water Assessment Tool (SWAT)模型的安装有些许复杂,如果是从没有接触过的同学,在安装时非常容易遇到问题。

以我的经验来说,要顺利安装SWAT需要具备以下几个条件:1.干净的系统。

最好是重新安装一个Arcgis9.2,然后到ESRI下载好SP4补丁。

2.最好安装在C盘。

由于SWAT软件是基于Arcgis开发的插件,所以还是有很多bug的,尽量使其在一个系统盘下面,保证其不出各种各样奇怪的问题;至于运行SWAT产生的巨大Project文件,可以存放在D盘等其他位置,但是要保证存放位置够大(10G的空闲空间是需要的)。

3.将系统的地区和语言均设置为美国,美语。

下文详细描述了模型的安装过程,供大家参考!原文地址:/SWAT的安装1 AVSWAT的安装:1)安装环境:ArcView 3.1 or 3.2 (software)Spatial Analyst 1.1 or later (单独安装的模块)Dialog Developer 3.1 or later (自带的模块)2)安装要点:先安装ArcView和Spatial Analyst模块。

然后解压AVSWAT安装文件,中文用户需要把区域与语言选项中把语言修改为英语(美国),启动ArcView,在File 菜单上单击Open Project,打开安装文件所在的目录,选择setup.apr,并单击OK。

2 ArcSWAT 1.0.7的安装:1)安装环境:Microsoft .Net Framework 1.1ArcGIS-ArcView 9.1 with service pack 2 (Build 766)ArcGIS Spatial Analyst 9.1 extensionArcGIS Developer Kit (usually found in C:\ProgramFiles\ArcGIS\DeveloperKit\)ArcGIS DotNet support (usually found in C:\ProgramFiles\ArcGIS\DotNet\)2)安装要点:①首先安装Microsoft .Net Framework 1.1;注意:很重要,否则第2步中将不会出现".NET Support",则ArcSWAT安装目录中不会出现"ProgramFiles\ArcGIS\DotNet",这就是网上很多人出现的常见错误"swat_hru.dll..."的原因。

(完整版)ARCSWAT模型使用

(完整版)ARCSWAT模型使用

ARCSWAT模型使用1. 模型介绍SWAT(Soil and Water Assessment Tool)是由美国农业部(USDA)的农业研究中心(ARS,Agricultural Research Service)Jeff Amonld博士1994年开发的。

模型开发的最初目的是为了预测在大流域复杂多变的土壤类型、土地利用方式和管理措施条件下,土地管理对水分、泥沙和化学物质的长期影响。

它是一种基于GIS基础之上的分布式流域水文模型,近年来得到了快速的发展和应用,主要是利用遥感和地理信息系统提供的空间信息模拟多种不同的水文物理化学过程,如水量、水质以及杀虫剂的输移与转化过程。

SWAT模型综合了早期开发的SWRRB(the Simulator for Water Resources in Rural Basins)模型和ROTO(the Routing Outputs to Outlet)模型的特征,从1990s 问世以来,经历了SWAT94.2,96.2,98.1,99.2,2000等版本,模型在原理算法、结构、功能等方面都有很大的改进,现在使用的SWAT2005版本可以在Arcview、ArcGIS等常见的软件平台上运行,具有良好的用户界面,在ARCGIS上的SW AT 模型为ARCSW AT。

本文使用的是ArcGIS 9.2支持下的ArcSW AT 2.0.0。

模型数据处理过程:SWAT模型所需的数据有地形、土壤、土地利用、气象、水文、营养物质等,根据研究目的不同可以选择建立不同的数据库,模型本身带有Land Cover/Plant Growth Database、Urban Database数据库。

除此之外,还需要结合研究区域的特点和研究目的,建立用户数据库,其中包括耕作数据库、杀虫剂数据库、营养物质数据库、土壤数据库。

模型数据处理流程如图2所示:模型数据处理流程模型的应用:模型的应用主要表现在8个方面:校准与敏感性分析,气候变化模拟,GIS平台描述,水文评价,结构和数据输入效果评价,与其他模型比较,多种模型分析的结合,污染评价。

arcswat2012使用经验及问题

arcSwat2012使用经验及困惑一使用经验1最初接触arcswat主要是看官方的视频,官方的视频看完之后,基本已经会操作了。

2 对于蒸发方式默认的是pengman公式,河道汇流演算如果想改成马根琼斯,修改bsn里可以找到。

3阅读cup使用手册。

4 观测值要去除预热期,不要包含预热期,之前我包含了预热期,也是一直出错。

2 注意的问题,(1)投影一定要选对,要知道不同的投影对流域的面积产生很大的影响,我之前用wgs_web默卡托投影就比选择albers投影大了很多。

(2)对于土地利用数据,如果自己没有做实验得来的数据,就把自己的土地利用数据按照美国的标准重新分类。

(3)土壤数据可以利用FAO的,还可以利用中科院数据中心的,比例尺都是1:100万,使用中科院数据中心的数据存在一个问题,那就是他给的数据只是到亚类,而具体的涉及土壤组成的参数必须到土种,所以需要根据土种志去寻找需要的参数,但是可能会遇到根本找不到参数的情况。

FAO数据比较方便,土壤粒径不用转换,但是只有2层数据,而且该数据跟数据中心的数据还是有很多不同的地方,大家可以仔细比对。

(4)注意FAO里的土壤深度单位是cm,而swat用的是mm。

(5)降雨站点应该选择流域内的站点,降雨站分布情况对模拟的径流有很大的影响。

(6)天气发生器制作使用群共享里的天气发生器,里面需要注意数据的格式问题,这个工具没有写数据的要求和格式,比如是否考虑了气象站数据的缺测,微量等等特殊数据。

(7)气象站数据已经有了相对湿度,平均风速,气温数据,自己利用pengman公式计算出太阳辐射。

这样就不要天气发生器了。

(8)一定要注意气象站数据的单位跟swat里的单位要统一,仔细核对数据的单位,气象站的数据单位很多都是0.1,需要除以10。

对于其他的特殊标识,一定要仔细搞清楚代表的是什么。

如果有缺测数据必须换成-99,如果有缺测的数据,那么天气发生器就必须需要了。

(9)气象数据等一定要连续,中间不能断开,比如说缺了一个月的数据,这样就不对。

swat源码编译

swat源码编译摘要:1.SWAT 源码编译简介2.SWAT 的编译流程3.编译SWAT 源码的步骤4.SWAT 源码编译的注意事项5.总结正文:1.SWAT 源码编译简介SWAT(Simplified Wrapper and Test 工具)是一款用于简化软件测试的工具,它可以帮助开发人员和测试人员快速地编写、运行和分析测试用例。

SWAT 源码编译就是将SWAT 的源代码转换为可执行文件的过程。

通过编译SWAT 源码,用户可以定制和优化SWAT 工具,以满足特定需求。

2.SWAT 的编译流程SWAT 的编译流程可以分为以下几个步骤:(1)预处理:在这一阶段,预处理器读取SWAT 源代码,并处理包含的头文件和宏定义。

(2)编译:编译器读取预处理后的源代码,将其转换为可执行的二进制文件。

(3)链接:链接器将编译后的目标文件与库文件进行链接,生成最终的可执行文件。

3.编译SWAT 源码的步骤(1)获取SWAT 源代码:首先,你需要从SWAT 的官方GitHub 仓库或其他可靠来源下载SWAT 的源代码。

(2)安装编译工具:要编译SWAT 源码,你需要安装C++编译器(如GCC)和相关工具。

在Linux 系统中,你可以使用包管理器(如apt-get)安装这些工具。

在Windows 系统中,你可以从MinGW 官网下载安装包。

(3)创建编译目录:在计算机上创建一个新的目录,用于存放编译过程中产生的文件。

(4)配置编译环境:使用文本编辑器编辑编译目录中的编译脚本(如Makefile 或CMakeLists.txt),设置编译选项和目标文件路径。

(5)编译SWAT 源码:在命令行中,切换到编译目录,并运行编译脚本。

编译过程可能需要一段时间,具体取决于你的计算机性能和SWAT 源码的规模。

(6)链接可执行文件:编译完成后,使用链接器将编译后的目标文件与库文件进行链接,生成最终的可执行文件。

4.SWAT 源码编译的注意事项(1)确保源代码的正确性:在编译SWAT 源码之前,务必确保源代码的正确性,避免因为错误的源代码导致的编译失败或运行异常。

SWAT模型建模中可能遇到的问题和解答

SWAT模型建模中可能遇到的问题和解答

ArcSWAT Frequently Asked QuestionsInstallation:1.Problem: During installation an error message containing “ … unable to get installer types …”appears, preventing successful installation.Solution: Make that the following is loaded on your system:a.) .Net Framework 2.0b.) ArcGIS DotNet Support (C:\Program Files\ArcGIS\DotNet). In order for ArcGIS DOTNetsupport to be installed, the .Net Framework 2.0 must be present on the target computer prior foinstalling ArcGIS.Solutions to Interface Problems and How-To:1.Problem: Error during Landuse/Soils/Slope overlay of “Item not found in this collection”.Cause: The SWAT2005.mdb crop or urban tables do not have a properly formatted OBJECTIDfield.Solution: Create a cop table with a sequential OBJECTID field by exporting the crop table back into the SWAT2005 database using ArcCatalog. Delete the old table and rename the new one to “crop”or “urban”2.Problem: Error at beginning of Landuse/Soils/Slope overlay operation.Possible Cause: Land use lookup codes begin with a number and not a letter. All land use lookupcodes in a user-defined landuse lookup table and also found in the crop and urban tables MUSTbegin with a letter.3. Problem: Error during watershed delineation of, “You attempted to open a database already opened…”.Cause: There is a renegade lock on a table or feature class in your SWAT project database.Solution: Close the SWAT ArcMap project. Reopen the SWAT project a try the operation again. It is a goods idea to save your SWAT project during the watershed delineation task after each step iscompleted.4.Problem: Error during the writing of SWAT input files, such as “Missing CN2 for hydrologic group…” .Cause: Soil lookup table of database usersoil table has problems.Solution: Soil names in the soil lookup and usersoil table CANNOT have “_” characters. Thesecharacters must be replaced by something else, such as “-“ or “#”.5.Problem: Errors while reading in observed weather filesCause: Make that there are no extra empty rows at the end of the tables. Also, check observed datafiles to make sure that there are no dates that are skipped in the middle of the file.6.Question: Observed weather data was loaded. However, during model setup, I can only select asimulation period that falls within the dates of my observed data. How setup a model “warm-up”period using simulated weather?Answer: You must add missing data values to the beginning of at least 1 of your observed weatherfiles. This will allow the model setup dates to span a wider range, allowing several years of “warm-up” prior to the observed data.7.Question: How to copy a SWAT project manually:1.) Copy the entire project folder to a new location.2.) Open up the SWAT project .mdb database (in new folder) using MS Access.3.) Open "MasterProgress" table. Update the "WorkDir" field to reflect the new project folder path.4.) Open the SWAT .mxd document in new project folder. It should be all set, and point to newfolder8.Problem: Some interface forms crash when exiting OR the help system does not work.Cause: Adobe Acrobat Reader version 8.0 or higher must be installed.9.Problem: I get an error loading my weather station dBase files.Cause: On some operating systems, the length of the dBase file name must be 8 characters or less(plus the extension). By making your station list table and the individual station table files withnames of less than 8 characters, this error should be resolved.10.Problem: When using user-defined watersheds option, ArcSWAT fails when writing the MGT filesusing the Heat Units calculator option.Cause: A likely cause is that the user watershed and/or stream dataset did not their projection defined.This will cause the heat unit calculator program to crash. Define the projection for the userwatersheds/streams datasets, then re-import through the watershed delineation interface. ArcSWAT Databases:1.Question: The ArcSWAT project databases contain an “ArcHydro” feature dataset where the finalwatershed delineation datasets are stored. This structure does not match the standard ArcHydrogeodatabase model. Why not?Answer: The ArcSWAT “ArcHydro” feature dataset contains feature classes that follow closely thestandard ArcHydro model, but not completely. These feature classes can be readily imported into astandard ArcHydro geodatabase.2.Question: In my SWAT project database, there are more records in the “hru” table than are found inthe spatial HRU layer, “Full_hru”. Why is this?Answer: In there are split HRUs into sub-hrus, then there will always be more records in the “hru”table than in the spatial layer. This is because we have made multiple tabular hrus out of a singlespatial hru.3.Question: In my SWAT project database, there are fewer records in the “hru” table than are found inthe spatial HRU layer, “Full_hru”. Why is this?Answer: In some cases, a land use or soils lookup table may have more than 1 value representing the same land use or soils class. In these cases, the spatial hru layer generated will have a single polygon for each unique combination of the raw dataset values, not the lookup values. However, in the hrutable, unique combinations that have the same lookup values will be combined into a single hru. Good Practices to Prevent Crashes:1.Unexplained crashing: Periodically, use the “Compact Database” function in ArcCatalog to compactthe SWAT Project geodatabase. This database can approach the 2 GB limit when working with very large datasets. Unexplainable crashes will occur when using the interface is this 2 GB limit isreached.2.Crashing during LU/Soils definition: Some ArcInfo coverage format soils or land use datasets mayresult in errors in the HRU analysis functions. It is best to use shapefile or ESRI grid formatdatasets.3.Crashing when using user-defined watersheds/streams: When using user-defined watersheds andstreams, the input watersheds and streams datasets must have exactly the same fields as defined inthe user documentation (Section 3 page 14). Otherwise, errors may result.Land Use/Soil/Slope Overlay Problems:1.If you manually re-assign a land use in the “SWAT Land Use Classification Table”, and you choosea land use class that is already assigned in the table, then you will experience a crash during theoverlay operation. The land use classes listed in the “SWAT Land Use Classification Table” must be unique prior to performing the overlay. The solution to this issue is to modify your land use lookup table so that multiple grid codes get assigned to the same SWAT land use class. In this case, theinterface will automatically reclassify the land use dataset based on the lookup table, resulting inunique lands use values in the “SWAT Land Use Classification Table”. NOTE: This same concept applied to the soils data as well.。

ArcSWAT 2.1.4 Release Notes
12/01/08
Updates\Bug Fixes from Version 2.1.3
General:
The most important update to ArcSWAT with version 2.1.4 was a fix to an error that was found to occur with watersheds that had draining inlets defined. The error would result in a crash during calculation of subbasin parameters. Other updates are minor bug fixes and an enhancement to the way exempt land uses are treated during HRU definition.
SWAT Project Setup:
1.None
Watershed Delineation:
1.Made a correction to error that occurred when calculating subbasin parameters for a model with
inlets defined. This error resulted from erroneous GRIDCODE values in a temporary
“WDCWATERSHED” feature class. This error was present in ArcSWAT version 2.1.2 and 2.1.3
and is now fixed at 2.1.4.
HRU Analysis:
1.Made a correction in the final HRU report. The full watershed area was not getting calculated
correctly in the report.
2.Modified the handling of exempt land uses. The new method preserves the actual area of the exempt
land uses and does not redistribute the area from those land uses that fall below the threshold area to them. This ensures that the original GIS-based are for these exempt land uses does not get altered.
Write Input Files:
1.Modified interface for editing the user weather stations. The interface now looks to the “wgnrng”
table to retrieve the min and max values used in tooltips and in value checking.
Edit SWAT Input
1.Modified interface for editing the user weather stations. The interface now looks to the “wgnrng”
table to retrieve the min and max values used in tooltips and in value checking.
2.New parameters in the MGT2 table, PST_DEP and IHV_GBM, are added as new fields to the
table for models created with earlier versions of ArcSWAT. An error was found to occur if the values for these new fields were not set to a default of “0”. This is now performed automatically when the fields are added to the table.
3.When loading a saved management schedule, errors could result in cases where the schedule being
loaded used a different scheduling method (i.e., date versus heat units) than the current method for the HRU. This error is now resolved.
SWAT Simulation
1.Fixed memory errors that could occur when writing point source files. This error was found to
happen when writing a large number of point source files during the “Setup SWAT Run” operation.
This error has now been fixed through memory releases.
2.Modified the setting of the ICLB parameter in “cio” table. In previous versions, it was possible that
following auto-calibration and resetting a default simulation, that the ICLB parameter would not
get properly set back to a value of 0. This has been fixed so that the ICLB parameter is always set
back to 0 whenever “Setup SWAT Run” occurs.。
