Abstract

Runoff and SOIL EROSION from agricultural farms is one of the important phenomena because of its impacts on farm fertility. In this regards, type of the irrigation system has the great effect on RUNOFF and SOIL EROSION. Sprinkler irrigation with traveling rain-gun may causes RUNOFF and erosion on field. One of the essential measures for controling and reducing of RUNOFF and SOIL EROSION under GUN SPRINKLER IRRIGATION is simulation of this phenomenon. In this regard EUROSEM MODEL is one of the computer models. However applicability of the model should be assessed. In this research efficiency of the EUROSEM MODEL for estimating RUNOFF and SOIL EROSION has been evaluated by using field investigation in a research farm with two slope land of 1 and 3 percent located in shahrekord University. Experiments were conducted under rain intensity of 38 mm/hr averagely with coefficient of uniformity of 89.5 percent.Results show that RUNOFF and SOIL EROSION can be successfully modeled by EUROSEM MODEL; but the model to estimate time of starting hydrograph and time of peak flow has more errors. The results show that accuracy of the model to estimate RUNOFF and sediment production is parallel and it was not shown significant difference between estimating of the parameters. In addition, verification procedure of the model shows that if the model to be calibrated for a certain event; one can simulate other events successfully by using the calibrated model. This means that the number of filed measurements can be reduced via application of the model.
