Study of Geometric Elements for the Proposed Protecting Dam Reservoir in Al-Fat'ha Area, Iraq

Partially constructed Makhul dam may collapse after the operation due to geological and geotechnical background of foundations zone, presence gypsum layers in this Then construction Al-Fat'ha protection is one proposed solutions. The present study used geometric analysis method investigate ability planned protecting reduce disasters break. new methodology derive elements two dams, analyze relations between these elements, then exam behavior with without studied scenarios. Fourteen scenarios suggested for dam, from level 140 m above sea (a.s.l), maximum possible flood 152 (a.s.l). A mathematical model was derived predict achieved as a response cumulative storage reservoir when occurred. face worst scenario 147 corresponding accumulated 3414305769 3 . results indicate that optimum operating conditions 118.5 which corresponds capacity (39243587) total flooded area dams calculated each dam; it about 44 km 2 nine villages on banks will submerge. Subsequently, confirmed contain direct wave caused by dam.
