5. At a certain point in an unconfined aquifer of 5 km area, the water table was at an elevation of 105.00 m. Due to natural recharge in a wet season, its level rose to 107.0 m. A volume of 1.50 Mm of water was then pumped out of the aquifer causing the water level to reach a level of 100.2 m. Assuming the water table in the entire aquifer to respond in a similar way, estimate a. Specific yield of the aquifer b. Volume of recharge during wet season.
