A confined aquifer has hydraulic conductivity of the aquifer, K =50 m/day and 0.2 of porosity. The piezometric head in two wells are 55 m and 50 m, respectively, which 1000 m apart to each other. The average thickness and width of the aquifer are 25 m and 5 km, respectively. Estimate The flowrate through the aquifer. Based on the result, describe the type of layer as shown in TABLE Q5(a) in terms of storability effect. (i) (ii) Time of travel from the head of the aquifer to downstream of 3.5 km by assuming no dispersion or diffusion along the aquifer. Discuss on what would happen if there are dispersion or diffusion occur along the aquifer due to pumping activity
