Hi
Using scientific methods to locate water
To locate groundwater accurately and to determine the depth, quantity, and quality of the water, several techniques must be used, and a target area must be thoroughly tested and studied to identify hydrologic and geologic features important to the planning and management of the resource. The landscape may offer clues to the hydrologist about the occurrence of shallow groundwater. Conditions for large quantities of shallow groundwater are more favorable under valleys than under hills. In some regions--in parts of the arid Southwest, for example--the presence of "water-loving" plants, such as cottonwoods or willows, indicates groundwater at shallow to moderate depth. Areas where water is at the surface as springs, seeps, swamps, or lakes reflect the presence of groundwater, although not necessarily in large quantities or of usable quality.
Geology is the key
Rocks are the most valuable clues of all. As a first step in locating favorable conditions for ground-water development, the hydrologist prepares geologic maps and cross sections showing the distribution and positions of the different kinds of rocks, both on the surface and underground. Some sedimentary rocks may extend many miles as aquifers of fairly uniform permeability. Other types of rocks may be cracked and broken and contain openings large enough to carry water. Types and orientation of joints or other fractures may be clues to obtaining useful amounts of groundwater. Some rocks may be so folded and displaced that it is difficult to trace them underground.
Existing wells provide clues
Next, a hydrologist obtains information on the wells in the target area. The locations, depth to water, amount of water pumped, and types of rocks penetrated by wells also provide information on groundwater. Wells are tested to determine the amount of water moving through the aquifer, the volume of water that can enter a well, and the effects of pumping on water levels in the area. Chemical analysis of water from wells provides information on quality of water in the aquifer.

about bore well
dear frinds
i need help for you friends. whats matter is my father-in-law want to test the land for bore well in his agriculture land but he is not sure if water is there or not in that land so he is hesitating to invest on bore well so please suggest any cheap and easy method to test the land for water . its very urgent if he have a bore well he wants to start a dairy farm in his village so please give me the information on this issue
thank u friends

Ground Water Development, Investigation and Management
Importance of Ground water in Agriculture:
The progress in India is due to progress in Agriculture. Due to progress in agriculture need of water is increasing day to day in the different practices. Land is the first of all need for Agriculture. The next need based priority is Water for every Agricultural practices.
Why Investigation Scientifically?:
The water availability on surface and underground is decreasing day to day. So the existing local methods in practice are not useful. Only scientific methods and instruments may give some satisfactory results.
Which method is more reliable and result oriented?:
The Resistivity method is more reliable and widely in practical throughout world for ground water Investigation. We apply Schluberger Method by operating Resistivity Meter
What instruments are used in the Resistivity Method:-
There are two instruments. One is Resistivity meter which is applied for ground water investigation to fix a pin point and detail study of underground formation (Strata) before making Bore hole/ dug well. Two is the logger Unit which is applied for groundwater quality investigation and strata in the bore hole after drilling it.
What would be the reliabilities in Resistivity Method for groundwater Exploration?
Resistivity Method is about 80 % reliable and widely is in practices throughout the world.
FOR ALL THE GUIDE LINES, SERVICES AND RELATED PROBLEMS THE INQUIRIES ARE HIGHLY APPRECIATED:
