Drainage Analysis of Mountainous Watersheds in Ras Al Khaimah Emirate, UAE
I. INTRODUCTION The United Arab Emirates (UAE) is devoid of streams or rivers that are perennial. However, several Wadis with different types and valley beds exist. Wadis generally dry, but they channel the runoff into their areas only during dry seasons. The runoff that is generated by the rains differs between one Wadi to another due to the the topography as well as headwater capturements. The mountains are where floods result of heavy rainfall. only a small portion of the water is absorbed by the Wadi beds , resulting in a quite a large amount of flood discharge. The majority of the annual rain thus reaches the plain, which is a fairly high annual runoff. The average annual runoff of the major wadis of U A E is about 120 MCM (11). In the piedmont regions in the piedmont, both runoff and infiltration are seen. This is why heavy rainfall can cause runoff, even in a relatively porous zone (gravel plain). The majority of annually falling rain in the region is absorbed by the dune zone. In a region where there is hardly any runoff the only loss of water is through the process of evaporation. The loss of water is directly proportional to the amount of days of rain and the depth of the rain.

Assessment of surface water is vital for water management, including flooding control, recharge assessment and the use of surface water in the water basin. Drainage analysis is conducted through morphological parameter analysis and the use of the model for rainfall-runoff. In this study, Ras Al Khaimah area of the northern emirates was chosen for the analysis of drainage. Fig. 1 shows a map of the location of the study area. The largest among the wadis is Al Bih was considered as a rainfall-runoff assessment. II. A CHARACTERIZATION OF MORPHOLOGICAL PARAMETERS Each hydrologic design is unique due to the fact that the elements that influence the design are influenced by location. The most important aspects are geomorphological parameters, land usage of the watershed and also the amount of storage. The morphometric parameters are utilized in numerous studies of hydrology of surface waters and geomorphology including the characteristics of floods and sediment yield. A Morphometric analysis of a watershed gives an insight into its topography, region as well as the geological state and runoff potential. Morphometric analysis is the study of three-dimensional topography of landforms. It has historically been used to study watersheds, drainages, hill slopes, and various other groups of features in the terrain [23.
