Abstract

Effective rainfall is one of the processes of the hydrologic cycle that has been studied very extensively. The various models proposed for description of this process are usually applicable to small plots, subjected to rainfall intensities that are higher than the infiltration capacity of the plots. In this paper we try to introduce a model which presented by Diskin and Nazimov. The model presented here in is not restricted to infiltration capacity only. It can also be used for computing the variations in the infiltration capacity rate and the production of RAINFALL EXCESS for any given rainfall hyetograph and a specified value of the initial moisture content of the upper soil layer. The model comprises two elements, a linear reservoir and a regulating element. The definitions of the two elements require three parameters: MINIMUM AND MAXIMUM RATE OF INFILTRATION CAPACITY (fc, fo) and the MAXIMUM VALUE OF MOISTURE STORAGE in upper soil layer. In order to calculate the amount of RAINFALL EXCESS, the model used in KECHIK WATERSHED, Golestan Province. The results show that the value of the RAINFALL EXCESS during a selected rainfall was about 55.9 mm.
