Webhydrograph separation of hydrographs from streams draining different geologic terranes have been used to show the effect of geology on base flow (Sloto and others, 1991, p. 29-33). White and Sloto (1990) analyzed streamflow hydrographs from 309 Pennsylvania streamflow-measurement stations to estimate base-flow-frequency characteristics.
WebA storm hydrograph is a type of graph that shows the changes in river discharge in the lead up to and following the start of a storm.
