AbstractThe work deals with the study of hydromorphology of the regulating lake which located at (50Km) north of Mosul city. The survey started in November, 2012 using the EchoSounder, and carried out by dividing the lake into (30) sections starting from the lower surface of the main dam and ending at the regulating dam. Data are recorded and represented using GIS technology (Arc GIs v10.4) and Microsoft program (Excel).
The survey shows that the shallowest depth in the lake is found at left bank of section (5) which reached (7.65 m) and the deepest point is Found in the left bank of the section (9) which reached (18.22m) directly on the Thalwage line. The hydraulic gradient of the lake is (1m/Km ), and the overall shape of the sections is (U) shape.
The variation in depth in each section is mostly due to difference in the sedimentation and erosion. There was deposition on the convex sides and erosion in the concave sides of the banks, the erosion and sedimentation processes vary with the variation of water velocity, slope and rock components of the river along the regulating lake.
