This presentation provides information on the process that needs to be followed to construct a deep tube well for agricultural purposes in Pavalangudi village of Vridhachalam Taluk, Cuddalore district, Tamilnadu. The extent of area is 100 acres. The presentation covers three stages of ground water exploration - surface, subsurface methods, well development and the methodology adopted.

Ground Water Exploration - An Introduction
A presentation that gives a detailed explanation of the methods and techniques of ground water exploration. tsbadri posted 12 years 1 month ago

The main objective is to study and understand the hydrological cycle of the region, to have an overall concept about the type, nature & number of aquifers, the quality of ground water.

Groundwater and hydrogeology - An introduction
A presentation that introduces water and hydrogeology tsbadri posted 12 years 1 month ago

This is a detailed introductory presentation about ground water and hydrogeology, and helps to understand the basics of ground water & aquifers. The branch of geology dealing with surface & subsurface water is known as groundwater. The science of hydrogeology is defined as hydrology with emphasis on geology.

Electrical well logging for groundwater exploration
tsbadri posted 12 years 2 months ago

Electrical well logging is a kind of geophysical logging tool for ground water exploration. It involves the continuous recording of electrical resistance, resistivity and spontaneous potential (SP) of formations of a drilled bore hole. This helps to identify the formations and also delineate freshwater aquifers from saline aquifers.It is also used to delineate the fracture system in hard-rock terrain, for rejuvenation of poor/low-yielding bore wells.
