Analysis of geo-morphometric and topo-hydrological indices using COP-DEM: a case study of Betwa River Basin, Central India

The open source 30 m Copernicus DEM (COP-DEM) has been used to derive the geo-morphometric and topo-hydrological characteristics of Betwa River Basin. Drainage network with 7th order stream mostly dendritic pattern delineated using Strahler’s method. drainage density, frequency, form factor, length overland flow circulatory ratio basin were computed as 0.38 Km/Km2, 0.08 Km−2, 0.23, 1.31, 0.20, respectively. These outcomes suggest less available surface flow, lesser relative relief, poor network, nearly elongated shape basin. mean bifurcation for entire was calculated 4.0 that signifies gradient dependent ruggedness number 0.24, which reflects geology dominated (granite–gneiss) rocky undulated topography dissection index ranges from 0.06 0.3, implies degree mature stage topographic wetness (TWI), power (SPI), terrain (TRI), sediment transport (STI) 3.13 26.35; 0 6; 30; 121.4, It lower is susceptible towards erosion compared upper
