WebSep 17, 2024 · Separating surface flow (SF) from subsurface flow (SSF) based on direct runoff measurements in river gauges is an important issue in hydrology. In this study, we developed a simple and practical method, based on runoff coefficient (RC), for separating SF from SSF. RC depends mainly on soil texture, land use and land cover, but we also … Webrecurrence interval water discharge: (1) the rational method (Chow 1964, Dunne and Leopold 1978, CDF 1983, Weaver and Hagans 1994), (2) the USGS Magnitude and Frequency Method (Waananen and Crippen 1977), and (3) ... runoff coefficient is constant across the watershed, and (4) the 100-year rainfall event produces the 100-year flood …
