• River - Can simulate riverine systems, and has been extended from Sacramento to Shasta Dam. Also has been tested with high flow/stage simulations for flood modeling.
• Estuary - Completely flexible estuary model; stages and flows may be specified at boundary and internal points.
• Land - Includes effects from land-based processes, such as consumptive use and agricultural runoff.

DSM2 can calculate stages, flows, velocities; many mass transport processes, including salts, multiple non-conservative constituents, temperature, THM formation potential and individual particles.

DSM2 Source Code

• DSM2 Source Code zipped files (1.72 MB, 5/25/2005)

  - Minimum requirements for the compilation of DSM2 (HYDRO and QUAL) source code:

  1. Compaq Visual Fortran Version 6.0
  2. Microsoft Visual C++ 6.0

- Steps to compile the source code

1. Extract all the files from the zipped file dsm2.zip.
2. To compile and create a hydro executable file, open hydro workspace "hydro.dsw" from the Compaq Visual Developer. Once compilation process is completed, the hydro executable file "hydro.exe" will be created under the folder "hydro/release" or "hydro/debug" depending on your selection.
3. Repeat the same process to compile and create qual executable file with qual workspace qual.dsw.
