Question

An 80 elevation would be 3 feet above the bottom of the excavation. The slope of the water table is 0.008, and the hydraulic conductivity is 80 feet per day (typical of a medium to fine sand) Assuming water flows in along all four side walls (equivalent to an area of 3 feet by 320 feet) and upward through the bottom (an 80 foot by 80 foot area), what pumping rate in gallons per minute, would be required to keep the excavation dry? As always, Q VA. foot by 80 foot excavation intersects the water table such that the normal water table
