A canal is dug parallel to a river, as shown in Figure P6.11. A sandy-silt seam of average thickness 0.5 m cuts across the otherwise impermeable clay. The average vertical and horizontal hydraulic conductivities are 1.5 × 10-5 cm/s and 15 × 10-5 cm/s, respectively. Assuming a 1-m length of canal, determine the flow rate of water from the canal to the river.
