Seepage analysis through and under hydraulic structures applying finite volume method

Abstract EN

In this paper, the seepage analysis through and underneath the hydraulic structures is studied at the same time without dividing the structure into parts, and then analyze each part individually.

The analysis has been done using the finite volume method using rectangular elements.

This method implemented on several types of structures and the comparison of the results is made with the one solved using finite element method.

The comparison showed close results.

The finite volume method has been implemented on non-rectangular structures.

The present work studied the effect of heterogeneous foundations on the uplift pressure and exit gradients at the downstream and comparison with homogenous foundations.

Also it studied the evaluation of effect of position and inclination of cut-offs at upstream or downstream of structures on uplift pressure and exit gradients at downstream.

In addition, it studied the effect of impervious body inside the structure or foundation on uplift pressure and exit gradients at downstream.
