The first course in hydrology/water resources engineering generally introduces the basic concepts, principles and application of the analysis and preliminary design of subsurface structures like wells for relevant components of the hydrologic cycle. This course on “Ground Water Hydrology” focuses on ground water availability/ flow/ storage/ intermixing/ investigation while simultaneously bringing out the advanced/ relevant theories/ practices/ techniques of practical importance. The topics to be covered include introduction, occurrence and movement of ground water, advanced well hydraulics, pollution and quality analysis of ground water, surface/ sub-surface investigation of ground water, artificial ground water recharge, saline water intrusion in aquifers, modeling and management of ground water.  The entire course material is quite useful for UG/PG students, teachers and professionals.  A number of selected problems will be solved to clearly illustrate the concepts.
