3 0 0 3<br />
Module I<br />
Vertical distribution <strong>of</strong> ground water. Types <strong>of</strong> geologic formations-properties <strong>of</strong> aquifer related to storage and<br />
transmissivity <strong>of</strong> water. Steady unidirectional flow-steady flow in a homogeneous aquifer-aquifer with recharge-<br />
Flow into infiltration galleries. Importance <strong>of</strong> groundwater modeling. Governing equations <strong>of</strong> ground water flow<br />
and boundary conditions (basic ideas only). Finite Difference discretization, Solution <strong>of</strong> partial differential<br />
equation <strong>of</strong> ground water flow for 1D steady ground water flow in homogeneous aquifers (confined and<br />
unconfined) using finite difference method (uniform mesh interval only).<br />
Module-II<br />
Partial differential equations governing unsteady ground water flow-unsteady radial flow towards well.<br />
Evaluation <strong>of</strong> aquifer parameters by Jacob’s, Theis and Chow’s method.<br />
Well flow near aquifer boundaries-Image well system. Method <strong>of</strong> images- Wells-Types.<br />
Method <strong>of</strong> constructing shallow wells- Method <strong>of</strong> constructing shallow wells -cable tool method, rotary method<br />
and reverse rotary method-well completion-design <strong>of</strong> gravel packed well-well development-different methods,<br />
well rehabilitation.<br />
Module III<br />
Surface investigation <strong>of</strong> ground water-different methods- electrical resistivity method, seismic refraction<br />
method-determination <strong>of</strong> aquifer thickness <strong>of</strong> horizontal aquifers. Quality <strong>of</strong> ground water- Graphical<br />
representations. Pollution <strong>of</strong> ground water-sources, distribution and evaluation <strong>of</strong> ground water pollution (Brief<br />
description only). Sea water intrusion-Ghyben- Herzberg equation-seawater fresh water interface-upconingpreventive<br />
measures. Artificial recharge <strong>of</strong> groundwater-different techniques.<br />
