For a homogeneous earth dam 50 m high having 2 m free broad, a flow net was constructed and the results were : Number of potential drops = 2.4 Number of flow channels = 0.4. If coefficiency of permeability of the dam mateiral is 3 x 10-3 cm3/sec, the discharge per metre length of dam, is
12 x 10-5 m3/sec
24 x 10-3 m3/sec

For shear strength, triaxial shear test is suitable because
it can be performed under all three drainage conditions
precise measurement of the pore pressure and volume change during the test is possible
stress distribution on the failure plane, is uniform
state of stress within the specimen during any stage of the test as well as at failure, is completely determined
all the above.
