Evaluation of the Effect of Drainage Geometry on the Behavior of Homogeneous Embankment Dams (Case Study: Kalan Dam of Malayer)

Embankment dams are one of the essential structures in civil engineering, and it is important to examine their various dimensions. In addition to affecting the water discharge process, drainage geometry also plays an important role in the after-filling behavior of embankment dams. In general, the safety of the dam is not only related to its design and construction, but it also depends on behavioral record of its performance in the first period of dewatering and operation, as well as regular service throughout the life of the dam (Ghareh and Nowroozzade, 2019, Komasi and Beiranvand, 2020). In These years, many modeling based on limiting equilibrium methods using different software has been performed. However, a broad view of the effect of drainage geometry on the behavior of homogeneous earth dams has not been done. Accordingly, this study investigates the stability of earth dams with a particular focus on drainage geometry. For accurate evaluation in this research, the Malayer dam has been studied.
