Monitoring the changes provides the decision maker with sufficient information to manage the storage capacity of the lake. Therefore, the main aim of this paper is to detect the changes in AHDL bed surface profiles in the period 2000-2012 using the remote sensing (RS) and (Geographic Information Systems) GIS techniques via building 3D profile of the lake. On the other hand, the measured values and directions of velocities along with the interpolation function are used to map, analyze and correlate the velocities pattern to the variation of the bed profile (the erosion and sedimentation patterns) and to the sediment component (particles) distributions.
