The Groundwater Toolbox: A Graphical and Mapping Interface for Analysis of Hydrologic Data

The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. It provides methods to estimate many of the components of the water budget for a hydrologic basin, including precipitation, streamflow, base flow, runoff, groundwater recharge and evapotranspiration.

Wellfootprint - A Map App for Visualizing Groundwater Withdrawals

Wellfootprint computes a raster map of groundwater withdrawals relative to a user-defined "Depth-Rate Index" (DRI), such as a recharge rate. Dividing each well's withdrawal rate by the length per time DRI yields an area for display for each well's 'footprint' as a circle around each well. Symbols for closely spaced wells are merged to visualize the combined withdrawals equitably.

Water, Energy, and Biogeochemical Model (WEBMOD)

The Water, Energy, and Biogeochemical Model (WEBMOD) uses the framework of the U.S. Geological Survey (USGS) Modular Modeling System (MMS) to simulate fluxes of water and solutes through watersheds. WEBMOD divides watersheds into model response units (MRU) where fluxes and reactions are simulated for several hillslope reservoir types.

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.
