Stream network hydrology
Web16 May 2024 · Abstract. To supplement the use of hydraulic tests and assess catchment-scale hydraulic conductivity (K), we propose a methodology for shallow aquifers only based on the Digital Elevation Model (DEM) and on the observation of the stream network. The methodology requires the groundwater system to be a main determinant of the stream … Webcorresponding drainage. So research on runoff and stream network is important to hydrology. And the stream network nodes present spatial structure and attributes of geography and hydrology in a watershed. Digital Elevation Model（DEM） digitally demonstrates the earth’s surface, in addition, it is the
