The W2 model, preprocessor executables, source code, and an example application: The model source codes and executables are in the file "w2v3.zip";. The executables (pre.exe and w2.exe) need to be run in the same directory as the input files (*.npt). There is no need to set up additional software to run the code, except perhaps the Array Viewer software from COMPAQ (see next section below). If you do not set up the COMPAQ Array Viewer, you will get an error when running the w2 executable, w2.exe. The executables should work with the enclosed example problems. Also a generic FORTRAN source code is included that does not have the COMPAQ Array Viewer information that the user can compile with his/her FORTRAN 90/95 compiler.

The GUI preprocessor: The GUI preprocessor is found in the file "gui.zip". There is a "setup.exe" routine that installs the Visual Basic W2 V3.5 Model Preprocessor called W2CONTROL. Once installed, the GUI preprocessor is able to aid the model user in setting up the Control File and in evaluating and changing the bathymetry of the system. This preprocessor does not automatically set- up the bathymetry of the system, nor does it provide post-processing support. A lot of effort is required to properly set-up the model bathymetry prior to using the Bathymetry editor within W2Control. Also, note that there may be updates to the file "w2control.exe". If there are, copy this new file over the one installed during the setup program. There is no need to run the setup program again. Note that there is now a separate pdf user manual for the GUI interface. Also, for users of Microsoft XP, there is no reason to run the setup utility. The exe file, w2control, will work without going through the setup routine.

User's Manual: On the web page the User's Manual is provided in a zipped PDF file.

Waterbalance Utility: The code and executable for this are in the file "waterbalance.zip". The purpose of this code is to approximate the waterbalance for a reservoir by computing flows (positive and negative) that will allow the model predicted water level to agree to water level data for a reservoir. There is a short Word document in the zip file that explains its use.
