IMPORTANT NOTE: Starting with IDC v4.0.266, the definition of irrigation trigger minimum soil moisture for non-ponded crops is changed. In the previous revision, it was defined as a fraction of the field capacity whereas in this revision it is defined as a fraction of Total Available Water (TAW = field capacity - wilting point) which is consistent with the definition listed in FAO Paper 56 (Allen et al., 1998). If migrating an existing IDC v4.0 application from a previous revision, it is important to note this change in the definition and update the values of irrigation trigger minimum soil moisture accordingly. However, if wilting point was set to zero in the existing application, there is no need to update the irrigation trigger minimum soil moisture values.
This file includes the list of changes in IDC with respect to the previous version.
This file includes the executable files for IDCv4.0.286 compiled for both 32 bit and 64 bit OS. When unzipped, the files will be restored into predefined directories, namely IDC, IDC_DLL and Budget. These executables are created by Intel Visual Fortran v2013.5.198 compiler. IDC4.0.exe (IDC4.0_x64.exe for 64 bit OS) is the executable for IDC that can be used on its own, IDC4.0.dll (IDC4.0_x64.dll for 64 bit OS) is a dynamic link library that can be used to link IDC to integrated hydrologic models, and Budget4.0.exe (Budget4.0_x64.exe for 64 bit OS) is the tool to post-process IDC output. Executables with "D" extension (e.g. "IDC4.0_D.exe") are in debug mode. It is recommended that the executables in debug mode are used when building a model from scratch. Once the model is built and debugged, the executables in release mode (e.g. "IDC4.0.exe") can be used for production.
Templates for Input Files
This file includes the templates for input files that are necessary to run IDC and the post-processor tool, Budget. When unzipped, these files will be restored into predefined directories, namely IDC and Budget. Template files for IDC_DLL are the same as those for IDC.
This file contains the Fortran source code for IDC v4.0 and a set of files that are required to create IDC and Budget executables. The source code is generated to be compiled by Intel Visual Fortran v2013.5.198. There are many source files and complex dependencies between these files. To help the user in building the executables, Microsoft Visual Studio 2010 solution and project files are also included with the source code. These files will be saved under the BuildAll folder. BuildAll.sln file under this folder can be opened from Microsoft Visual Studio 2010 and all IDC executables can be rebuild.
This file contains the IDC input and output files for a sample problem along with supporting GIS files. The sample problem utilizes several input data files in HEC-DSS database format to demostrate the usage of the DSS files. To view the contents of these files HEC-DSSVue, a free utility program developed by the U.S. Army Corps of Engineers, is required.
