Hi this is Pandit Pandit from India and I am working in watershed development project. Recently we have undertaken a watershed of 1000 hector for development. We need to calculate the total runoff from this watershed as a part of water balance study. I am looking out for some good and reliable methods to estimate the total runoff from this area. The average rainfall of the region is 2500 mm and the soil is sandy loam to loam , with slope of 5 to 30 %..
Hope to get some good suggestions, thank you.
