Calculates equivalent slope along a line using DEM
The Equivalent Slope, a pivotal hydrological characteristic for flood estimation in ungauged catchments in India, is precisely defined and applied by the Central Water Commission (CWC) within its Flood Estimation Reports (FERs) for various hydro-meteorological sub-zones. This parameter quantifies the average steepness of the main river channel, directly influencing the speed of flood wave propagation and consequently the time to peak of a flood hydrograph. This tool helps to find the equivalent slope of a given flow path from the terrain data.
