Two discharge wells (1and 2) penetrating an unconfined aquifer are pumped at constantrates of 3,000 and 500 m^3 per day , respectively. The steady-statehead (i.e., water table height) measured at an observation well is40 meters . The observation well is 50 meters from well 1 and 64meters from well 2. The water table height measured at a secondobservation well is 32.9 meters , which is located 20 meters fromwell 1 and 23 meters from well 2. Determine the aquiferpermeability K (in m/day).
