Estimating sediment yield from gully erosion using easily measurable morphometric characteristics in Darehshahr region, south of I.R. Iran

A case study was conducted in a part of Ilam Province, I.R. Iran, to establish a reliable model for estimating sediment yield from gully erosion. The attempt was satisfactory and led to an applicable model whose input could be obtained through a simple field measurement or applying remote sensing. The finalized factors can be found out through interpreting high resolution aerial photos or images and with the help of necessary soft wares or techniques. Although the model was statistically sound especially for the study area but the more numbers of gullies in different types distributed in miscellaneous climates and land uses may help to draw final conclusions.
