Abstract

Gully erosion is one of the developed and extreme types of water erosion that indicates sever soil loss. GULLY EROSION is more important than other surface erosions in SEDIMENT YIELD view point so that create many difficulties. GULLY EROSION also extends in many parts of IRAN and its study particularly in view point of SEDIMENT YIELD is therefore very important to be taken into account. The present study was taken place in DAREHSHAHR city in ILAM PROVINCE, IRAN, in order to investigate the relationship between SEDIMENT YIELD from GULLY EROSION and rainfall depth, intensities and duration. For this purpose, 18 axial, frontal and degitated gullies were precisely selected and their morphometric variations were surveyed at the beginning and end of 5 storm runoff events during November 2005 to January 2006. The important affecting factors were then determined with the help of factor and regression analyses. The results of the study showed that rainfall duration, 10, 30 and 60 minutes intensities were important factors controlling SEDIMENT YIELD by GULLY EROSION. The rainfall duration 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 duration with respective determination coefficient and estimation error of 81 and 28%.
