The knowledge of rainfall in terms of its intensity, duration, frequency, temporal distribution and droplet size distribution are important for appropriate estimation of runoff and erosion. That is required for hydrologic design of soil and water conservation structures. However the rainfall is the natural process and governed by the random processes. It takes several years to cover the entire range of above stated parameters and to study their effects on runoff and erosion. Therefore for quick understanding of this process and to accelerate the part of research on this aspect, it is...
