Abstract

The research aimed at determining the optimal control device in order to decrease seepage under hydraulic structures. The finite-element method is used to analyze seepage through porous media below hydraulic structures with blanket, cut-off, or filter trench as seepage control devices. The effect of length and location of the control devices is investigated.
The formulated optimization model is applied to a hypothetical case study. The optimization problem is solved by the Lagrange-multiplier method to find the minimum costs of control devices with safe exit gradient and uplift pressure.
For a hydraulic structure with different control devices, the minimum total cost has been achieved when using a filter trench, while the maximum total cost was when a downstream cut-off is used.
