Uncertainty Analysis of Seepage Flow in Soil Foundation of Small Concrete Dam

Hydraulic conductivity of soil has spatial variability due to complex configuration of soil. Therefore, regarding constant hydraulic conductivity in seepage analysis of soil foundation has high uncertainty.
In this study, seepage analysis of soil foundation in the small concrete dam was analyzed by considering uncertainty of hydraulic conductivity. In this respect, spatial variability of two-layer soil foundation was quantified using Monte Carlo simulation (Sharafati and Zahabiyoun 2014; Sharafati and Azamathulla 2018; Sharafati et al. 2018). Also, random variables were generated using Cholesky method and autocorrelated function of each layer.
