ABSTRACT
Background: Earth dams are one of the most important engineering facilities and an essential part of the infrastructure supporting the economy in various fields in Syria and other countries. Objectives: We focus in this research to determine the effect of the uncertainty in both saturation and residual water content of the unsaturated soil on the seepage through a homogeneous earth dam for steady state conditions as it will be considered as random variables, which provides the best simulation reflecting the actual situation of any similar engineering facility. Methods: A mathematical model for the dam was created using the Seep/W program based on the flow relationship that includes both the saturated and the unsaturated state, taking into account the uncertainty and unreliability of the studied parameters, after a code has been written for the governing equations of the unsaturated flow that allows the generation of random values form Their statistical characteristics and last been added to the Seep/W program through the Add-in function. The Monte Carlo simulation method (MCSM) was adopted to solve the seepage issue for a very large number of models (5000 models for the total cases studied in this research), each parameter was analyzed independently and a deterministic model was built for comparison. Results: The results show the minimal effect of the variance of the saturation content on the seepage for the studied soils in this research, and the possibility of neglecting the effect of its residual water content. Conclusions:  so saturated and residual water content for the unsaturated zone in homogeneous earth dams can be treated as deterministic parameters for steady state seepage.
Keywords Unsaturated soil - earthen dams - residual water content-saturated -water content.
