Rivendell Vadose Zone Monitoring System Installation

After much planning and coordination, Eel River CZO researchers gathered at the Rivendell experimental hillslope in Northern California to install a Vadose Zone Monitoring System (VMS).   The VMS is a custom flexible sleeve developed by Ofer Dahan and Sensoil Ltd. that houses samplers and sensors specially designed for complex unsaturated environments.  The VMS sleeve was installed into an inclined borehole, drilled at 55 degrees, and will collect access the unsaturated moisture that transits through the weathered and fractured rock above.
