Question

At a distance of 100 m and parallel to a river, a side channel flows through the river’s floodplain. The bed of the river and side channel are at the same elevation. At present, the depth of water in the river is 3 m and the depth of water in the side channel is 1 m. Assume the floodplain is composed of silty sand with a hydraulic conductivity (K) of 10^-5 m/s with no confining layers. Compute the discharge per unit width (Q*) of water flowing through the floodplain in m²/day.
