Question Paper
What is an aquifer How many types of aquifers are there Give a neat sketch of Leaky or semi-confined aquifer.
At a certain time the bulk density of the soil layer 20 -30 cm from the surface was 1·25 g/cm^3 . After 5 years of continuous cultivation, the bulk density increased to 1·4 g/cm^3 . Calculate the change in porosity of the soil, if the particle density is 2·7 g/cm^3 .
What is well development Explain in detail anyone method of well development.
Graphically show the following in a well pumping system in a partially penetrating well
Potentiometric Water Level
Static Water Level
Drawdown Curve.
Give a neat sketch.
Define the phenomenon of interference of wells. Explain in brief, why, in mines and the foundations, dewatering wells are very closely spaced.
Three closely spaced wells are pumped simultaneously. Using a schematic diagram, show their composite drawdown curve, if the .wells are laid in an unconfined aquifer.
What is Hypsometric analysis Explain its use in watershed management. What is meant by monadnock phase?
Explain the working principles of Electrical Resistivity Survey method of ground water investigation.
Define any two of the following:
Kelly's Ratio
Permeability Index
Soluble Sodium Percentage
Residual Sodium Carbonate
What is SAR (Sodium Adsorption Ratio) Discuss the ground water classification based on SAR of the samples.
What is Hydraulic conductivity? Discuss the procedure of laboratory determination of the hydraulic conductivity with constant head.
Discuss the conditions for which the Darcy law is valid.
Explain the storativity property of the confined and unconfined aquifers.
Discuss the role of tracers for obtaining information about ground water flow, ground water recharge and aquifer properties.
What is meant by Ground water Recharge and Discharge List the components of Ground water Balance.
Explain anyone of the following basic approaches of recharge:
Artificial Injection Method
Environmental Tritium Method
