Webdischarge under a unit hydraulic gradient is T= KB T is transmissibility fStratification f At a certain point in an unconfined aquifer of 3 km2 area, the water table was at an elevation of 102.00 m. Due to natural recharge in a wet season, its level rose to 103.20m. A volume of 1.5 Mm3 of water was then pumped out of the WebPorosity of an aquifer = specific yield + specific retention 0.40 = 0.25 + specific retention specific retention = 0.40-0.25 =0.15 Que.37) If ' p' is the precipitation, ' a' is the area represented by a rain gauge, and 'n' is the number of rain gauges in a catchment area, then the weighted mean rainfall is Answer: (c) Weighted mean rainfall can be calculated …
