UGT Hood-Soil Infiltrometer

Field measurement and calculation of the unsaturated hydraulic conductivity K(h) using Hood Infiltrometer (Umwelt Geräte Technik, GmbH.): The Hood Infiltrometer IL-2700 is a device used for determination of saturated and unsaturated hydraulic conductivities in-situ. Compared to other Infiltrometer designs (e.g. Perroux and White, 1988; Ankeny et al, 1991; Vandervaere et al., 1997; Špongrová et al., 2009 and others), infiltrating water is in direct contact with the infiltration surface, there is no need for any contact material, and only cutting the vegetation cover to the approx. 5 mm height is needed. The contact material creates an additional layer, which can affect the infiltration process and makes the subsequent data analysis more complicated.

This procedure is demonstrated step by step here on the video. However, reading the following text carefully is recommended before watching the video.
