The College of Engineering at the University of Baghdad held the public defense of master’s student Noor Mohammed Fayyad from the Department of Water Resources Engineering for her thesis titled
“Numerical Simulation of Hydraulic and Topographical Characteristics of Hamrin Dam Reservoir under Different Scenarios”
on Monday, September 2, 2024, in the Tigris Hall at the Department of Water Resources Engineering. The discussion committee consisted of Professor Dr. Thamer Ahmed Mohammed as chairman, with Assistant Professor Sadeq Alawi Salman and Assistant Professor Dr. Ameen Mohammed Saleh as members and supervised by Dr. Mohammed Rashid Thahir.
The thesis aimed to simulate key processes, specifically hydraulic simulations and sedimentation in the Hamrin Dam reservoir, using the HEC-RAS 6.4.1 model. The study indicated that the Hamrin Dam has experienced morphological changes due to human interventions or natural factors. Fieldwork was conducted to collect bottom soil and water samples to study suspended materials, and a two-dimensional model of bottom sediment deposits was created. The operation was simulated for a full year to obtain hydraulic results (depth, velocity, and water surface elevation), with results taken at maximum conditions and at the end of the operation, presented as color-coded maps.
The thesis concluded with several recommendations, including that the reservoir’s initial water level should not exceed 95 meters. Regular monitoring of sediment accumulation is essential, along with identifying its locations and causes, and conducting frequent surveys. It was suggested to establish an observation station to measure sediment quantities at the reservoir’s inlet and outlet and to develop an emergency plan that includes creating an alternative water passage for emergency situations. The feasibility of using the Salahuddin Channel to divert high flood waves should also be studied. Moreover, the thesis recommended enhancing hydraulic models, advising future studies to explore the use of three-dimensional modeling tools. A 3D model provides a more comprehensive understanding of vertical flow dynamics and sediment transport, enabling more precise identification of intervention points and improving sediment removal efforts.
After the scientific discussion by the committee members, and following the defense of the research, the student was awarded a master’s degree in water resources engineering
