Pumping Test Analysis of Large Diameter Wells in Pulang River Basin Cuddaph District

Pumping tests were carried out in a few selected open wells in a pulang river basin Cuddapah District. The wells are tapping water from weathered, fractured zones and river alluvium. Transmissivity storage coefficient and specific capacity are calculated based on Papadopulas-cooper and slichter's method. From the analysis it is concluded that though there is considererable variation in the aquifer characteristics from one well, to another well, the general pattern seems to be fairly uniform. The specific capacity of the open wells increases as the diameter of the well increases.
