The researchers conducted tests on bore wells in a fractured granitic aquifer in Southern India to understand their performance and characteristics. They found that the aquifer has varying transmissivity values, ranging from 10.28 to 90.06 m2/day, and specific capacity values between 10.40 and 67.31 lpm/m/dd. The Jacob straight line method was identified as ideal for determining the aquifer's properties. The aquifer showed a trend of increasing transmissivity from southeast to northwest, with some wells connected by highly transmissive fractures. Variations in transmissivity suggest the area has selective structural disturbances, leading to uneven development of fractures.
