One-Dimensional Transient Flow

Find the hydrogeologic parameters of the unconfined aquifer shown in Figure 11.1. The

aquifer is in a direct hydraulic connection with a large perennial river. The fluctuations of the

water table are recorded in a monitoring well (MW) 30 m from the river and are shown in

Figure 11.2. The hydrograph shows a sudden rise in the river stage and a consequent rise in

the aquifer water table recorded at MW1. From the available data, find the hydraulic

conductivity of the aquifer assuming it is homogeneous and isotropic. Also find what

would be the rise in the water table 8 days into the flood at 100 m from the river.
