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...

Design a trapezoidal channel that is capable of conveying 45 cfs from an elevation of 5000 feet to an elevation of 4500 feet. The total length from one point to another is 15 miles. The channel is to be rough concrete lined (n = 0.02). Try to minimize the amount of excavation required for the channel. If excavation costs are $5/cubic yard, determine the excavation costs. You should try to find the most efficient channel section. Use the area of...

1. Airy Isostasy. Given a mountain peak having an elevation of 8000 meters, use Airy's isostasy theory to estimate the thickness of its "root" assuming an average crustal density of 2700 kg/m3 and that the rocks in the mountain are 10% less dense that the surrounding average crust. What is the total thickness from the mountain top to the bottom of its root in kilometers? How does this compare to the thickness of continental crust? Sea level Niveau de la...

9) A rectangular channel 8 feet wide carries 2.5 ft/s of water at a depth of 3.2 feet. a) What are the most efficient attributes (d, A, P, and R) of the channel? b) If a 1-foot wide pier is placed in the middle of the channel, find the elevation of the water surface at the pier. What is the minimum width of the constriction that will not cause a rise in the upstream water surface?
