Abstract

This study evaluation of relationship between slop-area and precipitation parameters involve amount, intensively and duration with sediment yield by GULLY EROSION. The present study was taken place in BADREH watershed in ILAM PROVINCE, Iran, in order to investigate the relationship between sediment yield from GULLY EROSION and rainfall depth, intensities and duration and slop-area. For this purpose, 20 axial, frontal and digitized gullies were precisely selected, and their derange basin (slope-area) variations were surveyed at the beginning and end of six storm runoff events during November 2009 to May 2010. The consequential affecting factors were then determined with the help of factor and regression analyses. The results of the study showed that rainfall amount intensities were important factors controlling sediment yield by GULLY EROSION and slop 2-5% were effective for its. The rainfall amount was then found as the best indicator for sediment yield based on discriminative analysis. A significant relationship was ultimately established between sediment yield and rainfall amount with the respective determination coefficients of 871 %.
