Compute seepage velocity and estimate the hydraulic gradient

Reference no: EM13316196

A tracer dye is injected into a 55-ft thick sandy gravel confined aquifer which has a hydraulic conductivity of 1.2 x 10^-3 ft/s. The dye appears 14 days later in an observation well 75 ft away from the injection point. Compute the seepage velocity and estimate the hydraulic gradient in the aquifer if the porosity of the soil is 42%.
