Seepage Simulation of the Proposed Makhool Dam in North Iraq

This study aims to simulate water seepage and identify areas of weakness in the foundations through right left sides proposed Makhool dam northern Iraq, using finite element method by advanced computer software (SEEP/ W, 2012). The earth fill is 3670 m long on Tigris River. Many attempts were made ascertain program results supposed compare with those other analytical methods verify program. are comparable, showing that suitable for use analysis at dam. According analysis, quantity side acceptable within permissible limits; however, has a lot more than because presence cracks, fractures, cavitations stratigraphic sequence Fatha formation great depths gypsum beds under diaphragm. indicate need lower diaphragm about 6 extra foundation's zone level 49 m.a.s.l until reaching low permeability clay bed foundations' zone. action will reduce amount flow velocity avoid grouting during life. design limits piezometric head (total head) also determined, which be read monitoring devices when operating maximum reservoir normal levels.
