Design torrential rainstorm and its impact on water docks response using a form KINEROS well basin in the district of Shirqat - a case study

Abstract

Streaming Floods consider and what consequent the dangers, from the most important problems of natural environment in arid and semi-arid regions. Therefore, recent studies have focused on the development of programs and models have the ability to design rainstorms varying in intensity, sustainability and frequency and the resulting risks such as floods and sediment response of watershed. Including Kinematic model Erosion Model (KINEROS) and dynamic manner Wave Kinematics, watershed in response to runoff and erosion to a single rain storm. The problem comes in a difficult of predict the water yield for the seasonal valleys and produced sediments The research aim to attempt predict of floods and strong flooding by linking with the heavy rain storms on the region, which can be set up from the water harvesting projects and reduce the severity of the floods in wet seasons as well as reforming and restructuring land use and what suitable to use. The study area represent by Al-Bear Watershed located on left Bank from Sharqat District which is lie coordination between latitudes (35 36 22 ) and (35 31 20) to the north. and Longitudes (43 23 02) and (43 14 31) to the east. and an area of 50.29 km 2. The study relied on multi data and the most important design torrential rainstorm empirical with depth 55 mm and duration of rain 8 hours because of the lack of official data or hydrological station on the watershed, then inputted to KINEROS Model. With land cover data depending on the ETM Landsat 7, Map soils of UNESCO, DEM, and CN Curve Number. The study also relied on the most important software set such as KINEROS model that works in Arc GIS environment 10 and Erdas 9.3 software program and Global Mapper 13. To Run the Model and achieving objectives aims study.Keywords : KINEROS Model, design Storm rainfall , Water yield and Sedmintation , GIS & RS Techniqes .
