railway RRB JE (CBT I + CBT II) Mock Test 2024 Soil Mechanics and Foundation Engineering Seepage Analysis
An earthen dam is constructed on impermeable foundation, The coefficient of permeabilities of soil in horizontal and vertical direction are 5.2 × 10-8 m/s and 1.2 × 10-8 m/s. The water level on the reservoir side is 10 m from the base of the dam and number of flow channels is 4. The quantity of seepage per unit length in m3/s can be found using which of the following formulas?
1
\(Q=H.\frac{N_f}{KN_d} \)
2
\(Q=k.3H.\frac{N_d}{N_{df}} \)
3
\(Q=k.H.\frac{N_f}{N_{d}} \)
4
\(Q=k.\frac{N_f}{HN_{d}} \)
