Simulation model for Mosul Dam reservoir using HEC-ressim 3.0 package

الملخص EN

The present research aims to build a simulation model for Mosul dam reservoir using HEC-ResSim 3.0 package to study the operation behavior of the reservoir and the program capability to represent and simulate the real system.

The study based on monthly data for the period 1988 to 2006.

The current study results were compared with the results of previous studies which have considered the same reservoir.

The results showed that the program is very convenient in simulating the real system through testing and comparing model results with historical recorded data.

The results showed that the control rule curve of real reservoir operation does not match with the design operating curve (Original Rule Curve); due to the fact that Mosul reservoir has a problem with its foundation which contains large quantities of gypsum thus requires decreasing water storage to prevent its collapse.

The comparison of current study results with the previous studies showed that the current simulation model results are the closest to the actual observed operation data, This is because the HEC-ResSim 3.0 is a specialized software to simulate water resources systems, and considering many variables which are not taken into account in previous studies.
