| Abstract | ||
| The research aims to estimate the amount of surface runoff in the Wadi Al-Qaim basin depend on the rain falls and the morphometric characteristics of the basin, using the formulas designed by the US Soil Conservation Service (SCS-CN). So is the Berkeley method for estimating the volume of runoff. The search area (Wadi al-Qaim Basin) is located in the western Iraqi plateau within the Anbar Governorate. The valley ends in the Euphrates River at the city of Al-Qaim. It is located between latitudes (34° 9´ 55̋) and (34° 21´ 55̋) north, and longitudes (41° 7´ 10̋) and (41° 21´ 20̋ ) east. The depth of surface runoff for the Wadi Al-Qaim basin was calculated for several years from 2010 to 2019 using the SCS-CN equation depending on the characteristics of the land cover, the hydrological properties of the soil and the amount of rain fall. At the Rutbah station, the minimum runoff depth was 5.97 mm on 3/26/2010, depending on the rainfall amounting to 25 mm. As for the volume of runoff, and for the period between 2010 and 2019, the highest amount was 5239630 m³ on 19/10/2018 and the lowest amount was 1431606m³ on 26/3/2010 | ||
