Latest Patents

Annette holds a patent for the "Exfiltrometer apparatus and method for measuring unsaturated hydrologic properties in soil." This apparatus includes a container for holding soil and a sample container that is positionable with respect to the container. The sample soil in the sample container communicates with the soil in the main container. The invention features a first tensiometer that senses surface water potential at the surface of the sample soil, and a second tensiometer that measures subsurface water potential. Additionally, a water content sensor monitors the water content in the sample soil, while a water supply provides necessary moisture. A data logger processes the data from the sensors, enhancing the understanding of hydrologic properties.
