Hydrograph Separation Program
 Entry ID: USGS_HYSEP

[ Update this Record ]

Summary
Abstract: The Hydrograph Separation Program (HYSEP) performs hydrograph separation,
estimating the ground-water, or base flow, component of streamflow. The
program provides an automated and consistent method for estimating base flow.
Any of the three hydrograph-separation techniques of Pettyjohn and Henning
(1979) can be used: fixed interval, sliding interval, or local minimum.
