Jaber AL-Bakry Building and Construction Engineering Department, University of Technology/ Baghdad Received on:7/5/2009 & Accepted on: 10/1/2013 ABSTRACT In this paper, the seepage analysis through and underneath the hydraulic structures is studied at the same time without dividing the structure into parts, and then analyze each part individually. The analysis has been done using the finite volume method using rectangular elements. This method implemented on several types of structures and the comparison of the results is made with the one solved using finite element method. The comparison showed close results. The finite volume method has been implemented on non-rectangular structures. The present work studied the effect of heterogeneous foundations on the uplift pressure and exit gradients at the downstream and comparison with homogenous foundations. Also it studied the evaluation of effect of position and inclination of cut-offs at upstream or downstream of structures on uplift pressure and exit gradients at downstream. In addition, it studied the effect of impervious body inside the structure or foundation on uplift pressure and exit gradients at downstream. ﺗﺣ اﻟﻣﻧﺷـ وﺗﺣت ﺧﻼل اﻟﺗﺳرب ﻠﯾل ﺑﺎﺳﺗﺧدام اﻟﻣﺎﺋﯾﺔ ﺂت اﻟﺣﺟﻣﯾﺔ اﻟﻌﻧﺎﺻر طرﯾﻘﺔ اﻟﺧﻼﺻﺔ ﺗﺣﻠث اﻟﺑﺣذا ھﻲ ﻓم ﺗ ﯾﻰ اﻟوء اﻟﻠﺟ دوند واﺣ آنﻲ ﻓﺔ اﻟﻣﺎﺋﯾﺂت اﻟﻣﻧﺷت وﺗﺣﻼل ﺧرب اﻟﺗﺳ لﺔ اﻟﺣﺟﻣﯾر اﻟﻌﻧﺎﺻﺔ طرﯾﻘﺗﺧدام ﺑﺎﺳل اﻟﺗﺣﻠﯾم ﺗدة، ﺣﻰ ﻋﻠزء ﺟل ﻛ وﺗﺣﻠﯾل اﻗﺳﺎم اﻟﻰ اﻟﻣﻧﺷﺄ ﺗﻘﺳﯾم وﺑﺎﺳﺗﺧدام اﻟﺷﻛل ﻣﺳﺗطﯾﻠﺔ ﻋﻧﺎﺻر. ﻊ ﻣ اﻟﻧﺗﺎﺋﺞ وﻣﻘﺎرﻧﺔ اﻟﻣﻧﺷﺂت ﻣن اﻧواع ﻋدة ﻋﻠﻰ اﻟطرﯾﻘﺔ طﺑﻘت اﻟﺣل ﻧﺗﺎﺋﺞ ﺑطرﯾﻘﺔ اﻟﻣﻘﺎرﻧﺔ ﻧﺗﺎﺋﺞ ﻓﻛﺎﻧت اﻟﻣﺣددة اﻟﻌﻧﺎﺻر ﻣﺗﻘﺎرﺑﺔ. ﺂت اﻟﻣﻧﺷﻰ ﻋﻠ اﻟطرﯾﻘﺔ ﺗطﺑﯾق ﺗمﺗطﯾﻠﺔ اﻟﻣﺳر ﻏﯾﻛﺎل اﻻﺷ ذات. ﺎ واﯾﺿ اﻟﻣﺗر ﻏﯾس اﻻﺳﺄﺛﯾر ﺗﺔ دراﺳﺔ ﺟﺎﻧﺳﻊ اﻟرﻓطﻐ ﺿﻰ ﻋﻠﺧرؤ اﻟﻣد ﻋﻧدروﻟﻲﯾﮭ اﻟدار واﻻﻧﺣﻰ اﻟﺎﻓﺔ ﺑﺎﻻﺿﺔ، اﻟﻣﺗﺟﺎﻧﺳس اﻻﺳﻊ ﻣﺔ ﻣﻘﺎرﻧﻊ ﻣوﻗﺄﺛﯾر ﺗﯾم ﺗﻘﯾ ا ﻣﯾﻼن ودرﺟﺔ ﻟ ﺣواﺟزدروﻟﻲﯾﮭ اﻟدار واﻻﻧﺣﻊ اﻟرﻓطﻐ ﺿﻰ ﻋﻠﺄ اﻟﻣﻧﺷﺧرؤ ﻣ او ﻣﻘدم ﻋﻧدﺳﯾﺔأ اﻟرﺧرؤ اﻟﻣ ﻋﻧد. وﺟود ﺗﺄﺛﯾر دراﺳﺔ ﺗم ﻛﻣﺎﻊ اﻟرﻓطﻐ ﺿﻰ ﻋﻠﮫ اﺳﺎﺳ اوﺄ اﻟﻣﻧﺷ ﻓﻲ ﻟﻠﻣﺎءﺎذﻔ ﻧ ﻏﯾر ﺟﺳمﺧرؤ اﻟﻣ ﻋﻧدﯾدروﻟﻲﮭ اﻟ واﻻﻧﺣدار.
