Abstract

The large amount of available sedimentation in the reservoirs at different locations of reservoir bed implies the need for accurate hydrographic survey approaches. This approach is normally plotted to create bathymetric contour map. The aim of current study is to investigate the bathymetric contour map of the reservoir bed for Duhok dam and determine the volume of accumulated sediment within the local catchment conditions of Duhok reservoir for the period of 1988 to 2016 which has not been explored yet. Also, the life of the reservoir can be calculated. The study used the Acoustic Doppler Current Profiler (ADCP) integrated with the Global Positioning System (GPS) to record both vertical depth and horizontal position measurements, respectively. The data were processed and analyzed using RiverSurveyor Live software, and the topographic surface of the entire reservoir bed was created using AutoCAD civil 3D software. The results showed that the volume of sedimentation in the reservoir was about 8.0 million m3 for the period of 1988 to 2016, and the life of reservoir is 180 years since the commencement of the operation.
