Patent ID: 6986281

Claim:
Exfiltrometer apparatus for estimating at least one unsaturated hydrologic property of sample soil, comprising: a container for holding soil; a sample container for holding the sample soil, said sample container being positionable with respect to said container when said container contains the soil so that the sample soil contained in said sample container is in communication with the soil contained in said container; a first tensiometer operatively associated with said sample container so that said first tensiometer senses a surface water potential at about a surface of the sample soil contained in said sample container; a second tensiometer operatively associated with said sample container so that said second tensiometer senses a first subsurface water potential below the surface of the sample soil contained in said sample container; a water content sensor operatively associated with said sample container so that said water content sensor senses a water content in the sample soil contained in said sample container; a water reservoir operatively associated with said sample container so that water from said water reservoir may be introduced to the sample soil contained in the sample container; and a data logger operatively connected to said first and second tensiometers, and to said water content sensor, said data logger receiving and processing data provided by said first and second tensiometers and by said water content sensor.
