Annual Estimates of Water-Budget Components Based on Hydrograph Separation and PRISM Precipitation for Gaged Basins in the Appalachian Plateaus Region, 1900-2011
As part of the U.S. Geological Survey’s Groundwater Resources Program 
study of the Appalachian Plateaus aquifers, estimates of annual water-budget 
components were determined at 849 continuous-record streamflow gaging 
stations from Mississippi to New York. Base flow, which can serve as a proxy 
for annual recharge, …
