The incidents of dam failure occur due to some different reasons, in which the reason for seepage accounts for 35%. The seepage leading to the dam incidents can be divided into piping, internal erosion, solution of soluble rock, excessive internal pressures and/or saturation and excessive uplift, heave, or blowout. Currently, empirical method is commonly used to study the influence of seepage on the dam incidents. This paper presents a research work on the development of the experimental equipment and procedure for evaluating seepage effects on several physical properties of embankment, which include cohesion, friction angle, density and permeability coefficient. The testing results provide important material inputs to the finite element model used for the stability analysis of the main dam of Ta Trach reservoir (Thua Thien Hue Province, Vietnam) caused by the seepage phenomenon. � Springer Nature Singapore Pte Ltd. 2020.
