For the channel and river shown in Figure 2, determine the volume of water that flows from the channel into the river. The water surface elevations in the channel and river with respect to the underlying bedrock are 15 m and 11.5 m, respectively. The hydraulic conductivity of formation A is 5.6 m/day and that of formation B is 12.3 m/day.
