We discuss and demonstrate common tools for measurement of moisture and tension in the unsaturated zone, including tensiometers, TDR, and neutron logging. The Guelph permeameter and tension infiltrometer are used to determine K. We demonstrate suction lysimeters as a method of water sampling in the unsaturated zone.
Demonstration of TDR.
Class learns various methods to measure unsaturated K.
Demonstration of dual-tube infiltrometer.
Demonstration of dual-ring infiltrometer.
