Internal erosion is the second major reason for earth dam's failure after overtopping. One of the effective factors in internal erosion in earth dams is the clay minerals used in dams as well as the effects of compaction efforts on soil in sample preparation. In this research, internal erosion and the effect of clay minerals and compaction effort on internal erosion were investigated. For this ...

There are varieties of techniques for calculating natural frequency of the structures. Nevertheless, these equations are less developed in the geotechnical structures such as slopes, buttress group, dams, and retaining walls. In earth dams, with respecting to the dimensions and weight of dam, soil-structure interaction is of prime importance for finding seismic parameters including natural freq...

Dam break analysis plays a very important role in the risk assessment of dams. Large dams pose significantly higher risks to the people and property downstream of the dam as compared to smaller dams. So the flooding risk due to the possible failure of large dams is more crucial. The simulation of exceptional events characterized by high hydraulic and hydro-geologic risk is an actual problem for...

Earth dams can be a prehistoric phenomenon. These structures are designed to exploit surface water resources in certain positions in natural landscapes. In the plateau of Iran, surface water sources are generally seasonal. Seasons, when surface water flows abundantly, are late winter to the first half of spring. Meanwhile, according to the agricultural calendar, the peak demand for water for mo...

The article provides a detailed analysis of well-known studies, which allow considering the work structure together with base under dynamic influences, adequate replacement an infinite finite one using non-reflecting conditions on boundary region, methods for assessing behavior impact. A mathematical model, method, and algorithm were developed to evaluate earth dams shock impact non-reflective ...
