Runoff coefficient (C) is defined as the ratio of the volume of water superficially drained during rainfall to the total volume of precipitation during a certain period (Bedient et al., 2013; Júnior, 2015).An important tool in hydrological studies of many engineering projects in urban and rural areas (Şen & Atunkaynak, 2006), the runoff …
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 … Websensing and GIS for near real-time runoff estimation.
