Software
The USGS helps develop software packages and applications that are routinely used by federal, state, and public land managers.
Stochastic Empirical Loading and Dilution Model (SELDM)
SELDM is a database application where users can easily create and run highway-runoff simulations. SELDM simulates storm flows, concentrations, and loads. SELDM calculates the risk of exceeding water-quality criteria with and without user-defined BMPs. SELDM calculates annual runoff loads and is able to do a simple annual lake-loading analysis.
HEC-RAS
The purpose of this website is to enhance the support services provided to HEC-RAS customers. The HEC-RAS website provides a number of resources, which include helping the user download software, learn how to use HEC-RAS, resolve problems, report bugs, and suggest improvements to CEIWR-HEC products and service.
SPARROW modeling: Estimating contaminant transport
What’s New: A new version of the SPARROW code is being developed in the R programming language. The advantage of R is that it is non-proprietary and does not require a license or software cost. The R – SPARROW code is now being completed and should be available early in CY18. Stay Tuned.
Chemical Mixtures Software
The chemical mixtures software is a collection of computer programs for investigating the composition, occurrence, distribution, and potential toxicity of chemical mixtures. The software is designed to assist with selecting specific mixtures for future research, identifying the causes for the occurrence of specific mixtures, and discovering the effects of mixtures.

CE-QUAL-W2 - Hydrodynamic and Water Quality Model
CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.
Modeling Archives for PNW and CA SPARROW models
These modeling archives include the input data necessary to reproduce the results obtained from the SPARROW models developed for the Pacific Northwest and California.
