ECOMSED
HydroQual is pleased to announce the release of its state-of-the-art three-dimensional hydrodynamic and sediment transport model entitled "ECOMSED." ECOMSED is available for download to interested users by registering through HydroQual's website.  The software will be distributed only to registered users so that we can provide upgrades, “bug fixes”, etc. to users without delay. HydroQual reserves the right to limit distribution of ECOMSED at its sole discretion. Follow the link below to download the latest version of ECOMSED.

Brief Description
ECOMSED is a three-dimensional hydrodynamic and sediment transport computer code developed by HydroQual for application to marine and freshwater systems.  The component models are designed to execute in conjunction with each other so that output from one model is directly linked to the other models. The models share the same numerical grid structure and underlying numerical solution techniques.

The development of ECOMSED has its origins in the mid-1980’s with the creation of the Princeton Ocean Model followed by an upgraded version called ECOM for shallow water environments such as rivers, lakes, estuaries and coastal oceans.  In the mid-1990s, concepts for sediment resuspension and settling developed by W. Lick at the University of California, Santa Barbara were incorporated within the ECOM modeling framework.

Over the past several years, ECOMSED has been enhanced to include surface wave models, better bottom shear stresses for bottom boundary layer physics, noncohesive sediment transport, and dissolved and sediment-bound tracer capabilities.
