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 co - efficiency of permeability of the dam material is 3 × 10-3 cm3/sec, the discharge per metre length of dam, is
A flow net may be utilised for the determination of
Flow net is used for the determination of
If Nf, Nd and H are total number flow channels, total number of potential drops and total hydraulic head differences respectively, the discharge q through the complete flow is given by (where K is a constant)
Rise of water table in cohesion-less soils upto ground surface reduces the net ultimate bearing capacity approximately by
When the seepage pressure becomes equal to the pressure due to submerged weight of a soil, the effective pressure is reduced to zero and the soil particles have a tendency to move up in the direction of flow. This phenomenon is generally known
