Question

Groundwater

Let us assume that the water table on the island is 2 m above sea level. Then, t 2 m, so 2 m/0.03-h 66.67 m. Thus we can predict that if we drill a hole on the island we would not come to salty groundwater for approximately 67+ 2 meters, or about 69 m from the top of the water table. This would be 67 m below sea level. a] Suppose you found a place on the island where the water table was 2.75 m above sea level. How far would you have to drill below the water table to reach salty water? Show your work. b] You find another spot on the island where the top of the water table is 1.25 m above sea level. This is 100 meters from the place in [a]. You want to sink a well there that has a cross-sectional area of 1 m2. You have no pump so you must rely on natural flow for your water supply. You know that the hydraulic conductivity of the aquifer is 0.04 cm/sec. How much discharge (in liters) could you expect from the well per day? 16-16 Groundwater
