Abstract

Estimation of the amount of SOIL LOSS measurement of FIELD INDICATORS is a low-cost method, is easy to learn and can be simply applied. In order to measure and make assessment of SOIL LOSS amount by FIELD INDICATORS method in SHAHRAK WATERSHED, first map of the work units was prepared and then, measurements of the relevant FIELD INDICATORS were carried out within these units. Then, EPM model was calibrated and verified. Then the measured data for the amount of the SOIL LOSS obtained by using FIELD INDICATORS were analyzed and assessed using EPM EXPERIMENTAL MODEL. Mean of relative error and correlation coefficient between values from filed indicators method and EPM model were around 7.6 and 0.9, respectively which these results verify FIELD INDICATORS method for estimation of SOIL LOSS intensity. Estimation of the average of SOIL LOSS amounts relevant to each of the FIELD INDICATORS shows the following SOIL LOSSes: Rock exposure indicator: 47.61 (ton/ha), Pedestal indicator: 22.61 (ton/ha), Rill indicator: 5.67 (ton/ha), Sediment in drains indicator: 2.21 (ton/ha), Gully indicator: 2.17 (ton/ha) and Build up against barriers indicator: 34.78 (ton/ha).
