Estimate the surface runoff of the Bazyan basin in Sulaymaniyah governorate

Abstract

The study examined the Bazyan Basin within the tropical mountain area west of Sulaymaniyah Governorate, the importance of which stems from an estimate of the size of runoff based on the hypothesis of American soil conservation (SCS-CN).

Through a set of indicators to establish the relationship between land cover and hydrological soils to measure the pelvic surface nature of permeability and leakage based on remote sensing techniques and geographic information systems The CN value, which ranged from 58 to 91, shows that it has an adequate surface runoff, thus reaching the depth of the valley basin's surface runoff to estimate the size of the annual runoff (QV), which was the lowest value (6.22)
