Questions (page 2)

Section A

Q1. Write short notes on the following in not more than 5 sentences each :

(a) Hardness of groundwater and its significance

(b) Darcy's law

(c) Transmissivity and storage coefficient

(d) Piper diagram

(e) Lineament-based exploration of groundwater

(f) Perennial yield

(g) Runoff hydrographs

(h) Diurnal fluctuations in water table

Section B

Q2.

(a) What do you understand by the terms 'specific yield', 'specific retention' and 'porosity' of an aquifer? Also derive an expression to show their interrelationship.

(b) Explain hydrostatic equilibrium developed along coastal areas, and how excessive groundwater withdrawal may cause saltwater intrusion and contamination of an aquifer. Draw sketches to illustrate your answer.

(c) In the pump test of an aquifer, the discharge of water coming out of the pumping well is 5000 m3/day. The observation well is placed at a distance of 200 m from the main pumping well. If the intercept of the best fitted line on x-axis (i.e., time for zero drawdown) is 0.50 minute and the change in drawdown per log cycle time is 4.5 m, calculate the transmissivity (T) and storativity (S) of the aquifer by Jacob's method.
