OPTIMUM WATER ALLOCATION FOR ABO-ZIRIQ MARSH ECOLOGICAL RESTORATION

Optimum allocation of water for restoration Iraqi marshes is essential different related authorities. Abo-Ziriq marsh area about 120 km2 situated 40 km east Al-Nassryia city. After comparing the measured annual qualities with standards surface quality evaluation, was in acceptable limit. Hydro balance computation were done each month by using interface among HEC-RAS, HEC-GeoRAS and ArcView GIS software built a number eco-hydro relationships to simulate ecosystem HEC-EFM program estimate adequate requirement constructs hydraulic reference map show inundation area, depth grid velocity distribution, optimal flow result consists three scenarios (24, 30.3 33.6 m3 /s) operation during year. A computer MATLAB 7 developed optimization model determine optimum value entry lower zone. The priority parameter represented weight associated them (penalty factor). used scheme penalty factor examines cases (wet, moderate dry years). results obtained from run that values are not affected significantly changing factors.Hence, any set solutions can be use control structure two inlets zone best fits objective system increase release Abo Jiry inlet minimum deviation most time year
