An excavation is made for a canal that is fed by a stream, as shown in Figure P6.12. The measured flow into the canal is 0.25 × 10-4 m3 /s per unit area. Two pore water pressure transducers, A and B, placed along a line parallel to the slope and approximately at the canal mid height gave readings of 3 kPa and 2.5 kPa. Assuming flow parallel to the slope, estimate the hydraulic conductivity.
