The Estimation of Downstream Piping of a Dam (Case Study: Dewerige Dam- Iraq)
The study deals with the geotechnical and hydrological problems in Dewerige dam. It's a new hydraulic structure constructed on Dewerige river in the southeast of Misan governorate, which represents a multipurpose. The dam is used for flooding control, water storage for irrigation, and recharges groundwater. The current study aimed to study seepage quantity under a small concrete dam (weir). SEEP/W software has been used to solve a simulation model at steady stat to evaluate piping downstream (Toe) in saturated soil. Uplift pressure, seepage velocity, hydraulic gradient, and piping safety factor were calculated in SEEP/W. The model results explain that the piping safety factor was (1.7), Therefore, the dam is relatively safe against piping problems in flooding conditions.
