| Summary: | This study aims to determine the basic hydrological characteristics in the Rezan River Basin and their role in the occurrence of torrential and flood risks and to determine the most important effects that torrents and floods leave on the nature of the region and human activities in it. The inductive approach and statistical method were used to trace the precise parts of the topic to reach general conclusions. The US Soil Service model (SCS-CN) method was adopted to estimate the volume of surface runoff using a program (WMS). The model (SCS-CN) was applied ten times using rain showers ranging from (20-200 mm), with a difference of (20 mm), in addition to a real rain peak.
The study found that the depth of surface runoff in the study area increases with the increase in the amount of precipitation. it’s reached (52.6) mm in the Haji-Bag Basin, and (45.2) mm in the Baraz-ger basin, At the rain peak recorded at Mergasur station, amounting to (176.5) mm. The flow volume in the Haji-Bag basin (16654320) m3 and in the Baraz-ger basin (51241607.2) m3. The study showed that water torrents in the Rezan River Basin cause a lot of damage to elements of the natural and human environment.
