With the measurements in the following table, calculate the soil moisture flux q (cm/day) between -23 K = 240(-Y)* depth 0.5m and 0.8m in each week. Hydraulic conductivity (K in cm/day and Y in cm). Use the average suction head to derive hydraulic conductivity. For 1km area, how much water has passed the layer between 0.5m and 0.8m in these two weeks (in m)?
