Pennsylvania Water Science Center


The Pennsylvania Water Science Center has developed software tools to screen for potential water availability problems and to estimate daily streamflow of natural and anthropogenic affected streams throughout the Commonwealth of Pennsylvania and the entirety of the Delaware River Basin. We also developed a tool to visualize groundwater withdrawals relative to a user defined hydrologic scale.

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 - 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.

The Delaware River Basin Streamflow Estimator Tool (DRB-SET)

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.
