Q3. Explain briefly the basic principles involved in the development of IUH by :
(a) Clark's method
(b) Nash's model.
Q4. Give the uses and limitations of Unit hydrograph. The IUH of a catchment is a triangle with a base of 36 h and a peak of 20 m³/s at the start. Derive a 2-h unit hydrograph for this catchment.
Q5. Derive the basic differential equation governing unsteady groundwater flow in a homogenous isotropic confined aquifer. State clearly the assumptions involved.

Q6. A confined horizontal aquifer of thickness 15m and permeability K= 20m/day, connects two reservoirs M and N situated 1.5 km apart. The elevations of the water surface in reservoirs M and N measured from the top of the aquifer, are 30.00 m and 10.00 m respectively. If the reservoir M is polluted by a contaminant suddenly, how long will it take the contaminant to reach the reservoir N? Assume the porosity of the aquifer n = 0.30
Q7. A 45 cm well penetrates an unconfined aquifer of saturated thickness 30m completely. Under a steady pumping rate for a long time the drawdown at two observation wells 15 and 30m from the well are 5.0 and 4.2m respectively. If the permeability of the aquifer is 20m/day, determine the discharge and the drawdown at the pumping well.
Q8. What are the various methods of groundwater recharge? How is groundwater recharge estimated?
