Abstract EN

Basin Valley Dwiridj valleys of seasonal area of 3537 km 2 located in Maysan province, southeast Iraq and extends inside Iranian territory in the province of Ilam in the southwest of the Islamic Republic of Iran.

Been relying on the premise soil conservation US known (SCS-CN) for estimating the size of the runoff and technology remote sensing to determine the type of soil hydrological and determine the type of land cover and type Almkashv ground of rocks and soil and plant and disclosure of compositions written after the division of the basin into three sections varying space to determine the pelvis of the most influential where he found that the basin Dwiridj President contributes the highest percentage for the formation of runoff value (1.0667 billion / m 3) Then basin (1) of $ (276 740 000 / m 3) and swimming (2) of $ (158 910 000 / m 3) during a rainstorm and one as varied between peak discharge (1014.4 m 3 / s) and (269.1 m3 / s) time of concentration variation between 8-3 hours is a short time increases the risk of flooding for the three basins and basin main.
