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.

The R package wrv is for processing the groundwater-flow model of the Wood River Valley (WRV) aquifer system, south-central Idaho. The groundwater-flow model is described in the associated model report and model archive. Included in the package is MODFLOW-USG version 1.3, a U.S. Geological Survey (USGS) computer code that solves the groundwater-flow equation.
