تحديد الخصائص المورفومترية لحوض وادي الرواكيب باستخدام نظم المعلومات الجغرافية

الملخص EN

The study Investigated and analyzed the morphometric and hydrological characteristics of the drainage basin of Wadi El-Rawakib in west Omdurman ( Sudan ) using GIS and remote sensing data.

The study has tackled the main morphometric and characteristics that form and influence the hydrological system and drainage characteristics of the basin such as the drainage and related measurements and shape of the basin and its impact on the amount of water allocated and the topographic characteristics of the basin and their impacts on runoff in the calculation of dimensions and areas and distances involved.

Wadi El-Rawakib has a characteristics have had a direct impact on water resources, where the total area of drainage basin ( 1538 km ) and the number of Streams orders are ( 5 ) arranged by bifurcation ratio and reached as far as ( 4% ) for the order five.

The total length of Streams orders are about ( 492.6 km ) to the order one and (53.2 km) to the order five and this difference in the lengths of the number of streams order was in the first order more than the number of orders in the fifth order and the other order.

The study proved that the benefit from studying the Characteristics of Morphometrics to identify the various aspects has important in the field of geomorphology and hydrology related to difference projects such as dams and reservoirs.
