Comparative assessment of micro-watershed silt load with morphological parameters to evaluate soil conservation strategies

The comparative assessment of morphologic runoff and annual silt load from micro-watersheds can help in establishing relationships between these parameters with objectives of controlling runoff, conservation of soil, reduction of reservoir silt load and enhanced groundwater resources in the micro-watersheds. The automated watershed delineation technique using the filled digital elevation model is observed to be reliable for area having converging slopes. The estimation of watershed based annual silt load using universal soil loss equation along with runoff estimation utilizing the soil conservation services model using remote sensing data is possible on such automatically delineated micro watershed groups.
