Introduction. Partially penetrating wells:. aquifer is so thick that a fully penetrating well is impractical. Increase velocity close to well and the affect is inversely related to distance from well (unless the aquifer has obvious anisotropy). Hydrogeology.

If the distance and the observed . piezometric. surface drop between two adjacent wells are 1000 m and 3 m respectively, find an estimate of the time it takes for a molecule of water to move from one well to the other. K is 3.5 m/day and effective porosity is 0.35 . 2.8.1 The coefficient of storage of a confined aquifer is found to be 6.8 x 10. -4. as a result of a pumping test. The thickness of the aquifer is 50 m and the porosity is 0.25. Determine the fractions of the expansibility of water and compressibility of the aquifer skeleton in making up the storage coefficient of the aquifer. Md.Taufique. . Warsi, . Farooq A.

Managed aquifer recharge (MAR) includes a wide variety of different techniques with which water (e.g. stormwater, surface water or treated waste water) is intentionally introduced into an aquifer to store, treat the water.
