Presentation transcript:

1. A flow in permeable layer of soil like figure below q = 1 ft3/hr Question : Find the permeability coefficient of sand in ft/min

1. Permeability experimental conducted in laboratory as figure below Questions : determine h determine q in cc/sec

3. A dam is constructed on a permeable stratum underlain by an impermeable rock. A row of sheet pile is installed at the upstream face. If the permeable soil has a hydraulic conductivity of 150 ft/day, determine the rate of flow or seepage under the dam.

4. There is an earthen dam 13 meters across and 7. 5 meters high 4. There is an earthen dam 13 meters across and 7.5 meters high.The Impounded water is 6.2 meters deep, while the tailwater is 2.2 meters deep. The dam is 72 meters long. If the hydraulic conductivity is 6.1 x 10-4 centimeter per second, what is the seepage through the dam if n = 21
