Unsaturated Slope Stability and Seepage Analysis of a Dam

The paper presents stability and seepage analysis performed in unsaturated regime to take care of the infiltration through the dam. Seepage analysis is divided into two stages: steady state analysis and transient analysis. It will be determined the pore water pressure load, the ground water level, estimate the flow (path and quantity) and also, an advanced analysis considering rainfall and rapid drawdown. Van Genuchten model will be used for the unsaturated soil.
