Morphometrie Analysis by Using Remote Sensing & QGIS Approach to Evaluate the Aquifer Response of Two Sub Watersheds of Coastal Kerala

Abstract Global increase in demand of water resources stepped up due to climate change and population, stimulates an efficient development, management conservation by quantifying the available within catchment bridge gap between its availability. Initiated at a watershed scale, it is important quantitatively evaluate geomorphological parameters, since all hydrologic geomorphic processes may be accounted balanced watershed. This study presents excellent morphometric characterization Payppara Tikovil sub watersheds Meenachil basin, state Kerala, India, evaluated using SRTM DEM 30m×30m spatial resolution as input QGIS. The linear aspects like stream order, length segments, bifurcation ratio, Rho coefficient, areal form factor, drainage density, frequency, elongation overland flow relief ruggedness number, were calculated for comprehensive understanding characteristics general terrain was found steep but relatively mild Payppara. gravity paths traced few 4 th 3 rd order 2 nd segments identified potential groundwater recharge zones. derived benefits better formation erosive permeable surface response precipitation, principal hydrological budget.
