Low (top) and high (bottom) flow video images, Frankford Creek, PA
Still images from videos of surface water flow overlaid with velocity vectors during low (top) and high (bottom) flow conditions in Frankford Creek, Philadelphia, Pennsylvania, September 2020. These videos were processed using large-scale particle imaging velocimetry (LSPIV) to estimate streamflow in a location where standard methods are inadequate.

Fair weather cumulus at Chester County, PA Observation Well CH 10
Chester County, Pennsylvania Observation Well CH 10. The well is 33.5 feet deep, and lies in the local Cockeysville Marble Aquifer, part of the larger Piedmont and Blue Ridge carbonate-rock National Aquifer. The well is relatively new to the Groundwater Quality Monitoring Network (GWMN) consisting of 27 wells distributed over 26 counties in Pennsylvania.
