Slope Stability Study of Al-Qaim Dam that Proposed to be Constructed on Khosar River – Case Study

It is extremely significant during the design stage of an earth dam is to analyze the seepage and slope stability. The proposed Al-Qaim dam on Al Khoser river was used as a case study to apply Geo-Studio 2012 program and its appendices Seep/w and Slope/w. Some minor modifications to the original design suggested by SOGREAH company have been proposed. The Geo-Studio 2012 program was used to analyze three states of Al-Qaim reservoir i.e. (end of construction steady-state and rapid drawdown). Seep/w and Slope/w have used to analyze the seepage and the stability of the slopes the results reveal a good agreement between this analysis and the design company's results. Moreover the present analysis achieves the requirement of safety with less volume of embankment which reduces the cost of construction substantially.
