Abstract
The steady state seepage analysis is used to compute the factor of safety against piping for Teeb weir in the eastern part of Maysn. Teeb weir is a one of a swarm of hydraulic structures that were suggested and designed to reduce flooding risk in the Teeb area, and to work as a water harvesting system to recharge ground water in the area. The geotechnical engineering map is drawn to analysis the soil properties and estimate the suitability of the soil to support foundation of the weir body and downstream reservoir. SEEP/W software is used to solve the water seepage model underneath the weir foundation. Only the saturated model is selected to compute the factor of safety against vertical piping and to denote the zone of potential piping erosion. The model results show that the stability is critical and that there is a high possibility of failure expected, especially in the downstream zone.
