Software is provided for scientific analyses of data about Pennsylvania's water resources.
USGS developed, in cooperation with the Office of Surface Mining Reclamation and Enforcement, “user-friendly” aqueous geochemical modeling tools to simulate changes in water quality during passive and active treatment of acid mine drainage.
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.
The Delaware River Basin Streamflow Estimator Tool (DRB-SET) estimates baseline and altered streamflow at a daily time step for ungaged stream locations in the Delaware River Basin for water years 1960-2010.
