Water in the Earth has originated from seas and oceans and after the evaporation and climbing to the upper atmosphere, will return to lands in the form of precipitation, ,and after different changes ,again pours into the seas . This cycle is repeated over and over. In about half of the precipitation on surface are evaporated and with the water which is the result of transpiration of plants and animals, will return to atmosphere and about a quarter of this precipitation permeate into soil and creates underground water resources.

Due to hand-water well drilling restrictions by humans, in about 600 years before Christ (bc.); for the first time , the Chinese invented a simple tap drilling machine and by means of which they could dig wells to depths of 600 meters. By moving Chinese experiences  to the west in 1800 Ad, as industrial progress and development of human communities and need to supply water from deeper sources, advanced tap-drilling machines were created which worked by steam power and its system was gradually completed.

The Evaluation of discharge of wells or pumping tests is performed to determine the Hydrulic characterization of water table in order to studying the status of a regional groundwater and drop in water level in a well. The main goal of the experiment is determining the capacity of the well or the proportion of discharge (Q)to the drop in water level (s) in order to selecting pump and accessories for estimation of costs for equipping wells.

Due to the high investment costs of construction of wells, series of activities to increase operational life time should be planned to prevent the death of wells, these activities include physical conditions, biological conditions and chemical conditions which have adverse effects on well also the efficiency of well is reduced.

For better understanding of the groundwater resources, using new technologies and exploratory studies are necessary. The progress of technology in developing countries in the field of studying the water resources was accompanied by making devices and machine tools which cause growth and development of these countries, one of the devices using the external model is video meter which is invented by some scholars and researchers of our country. However, this device is different from its foreign equivalent, but their functions are the same.
