The USGS has developed software that is routinely used by federal, state, and public land managers. The USGS uses this software as wells as software developed by other agencies to support its science work.

HyMED Hydrologic Model Evaluation for Drought

This package facilitates the analysis and evaluation of hydrologic model streamflow output during periods of drought. This package calculates the Cohen's Kappa, Spearman correlation coefficient, ratio of standard deviation, percent bias, normalized mean absolute error (NMAE) in the annual time series of drought duration, NMAE in the annual times series of the distance the minimum percentile is bel

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.
