Lab Quiz 7 - Soil Water Flow

Water always moves

From a high potential to a low potential

How could you increase the water flow under saturated flow conditions through the soil for a given time?

increase the pressure potential

What would be the flux through the soil in question 9 above for saturated flow conditions when there is no ponding (no overlying water column)?

2

What is the hydraulic potential gradient for saturated flow for the above soil when there is no overlying water column (no ponding)?

1

What was the water flux (cm/hr) through the soil?

168

If the water flux through the soil column above is 10 cm/hr during saturated flow, determine the hydraulic conductivity (Kw) for the soil.

2

What was the saturated hydraulic conductivity (cm/hr) of the soil?

28

What is the hydraulic potential gradient (cm/hr) for saturated flow when a 20 cm water column is maintained on top of the soil column?

5

What was the hydraulic potential gradient?

6

Which of the following soils would have the highest saturated hydraulic conductivity?

sandy loam
