Solved 2. Unconfined aquifer drawdown - Dupuit Equation A
Question: 2. Unconfined aquifer drawdown - Dupuit Equation A well in an unconfined aquifer with thickness of 300 ft creates drawdown (Dw) = 20 ft at the well, which decreases to zero at a distance of 600 ft from the well. Aquifer hydraulic conductivity (Kn)= 1.15 ft/day. a. Calculate long-term equilibrium pumping rate in gal/min: _gpm b.
Solved 1a. An unconfined aquifer with a specific yield of - Chegg
1a. An unconfined aquifer with a specific yield of 0.13 has an area of 123mi2. The water table drops 5.23ft during a drought. How much water was lost from storage? b. If the same aquifer had been confined with a storativity of 0.0005, what change in the amount of water in storage would have resulted? (Note: 1mi2=2.7878×107ft2)
Solved 86-88. An unconfined aquifer is situated above a - Chegg
86-88. An unconfined aquifer is situated above a horizontal impervious base and is composed of sand with a hydraulic conductivity of 12m/day. In this aquifer, two fully penetrating ditches from a strip of land with a constant width of 1250m. The water level in the left and right ditches rises to 8 and 12m above the impervious base, respectively.
