Effect of water-permeable foundation layer thickness on filtration flow data with approximate e quality of dam body and its foundation filtration factors

Hydraulic (approximate) method is used to analyze filtration flow data of earth dams emplaced on water-permeable foundation of different thickness with approximate equality of dam body and its foundation filtration factors. Redetermination necessity of filtration flow data was discovered as a result of comparative analysis of water-permeable foundation layer thickness effect on filtration flow data.
