The hydraulic conductivity of soil is 0.003cm/s. Water flows from reservoir A to reservoir B through the soil with an 80-meter path length. If the change in elevation between the reservoirs is 20m, calculate the hydraulic gradient.

Calculate the effective hydraulic conductivity for flow parallel and perpendicular to layering. Please show and explain the difference in values.

A soil sample is placed in a 1m long and 10cm diameter tube. A constant supply of water is allowed to flow from inlet to outlet. The total water head at the inlet is 2m and the total water head at the outlet is 1m. The hydraulic conductivity is 0.001 cm/s. Which of the following answer is correct? O a. The flow velocity is 0.001 cm/s Ob. The flow velocity is 25 cm/s c. The hydraulic gradient in the tube is 2 Od. The hydraulic gradient in the tube is 0.001

a. For Figure 2 below, calculate the effective hydraulic conductivity for flow parallel and perpendicular to layering. Show your work. Explain the difference in values.
