Soil Water Content and Ground Water Pressure

The monitoring site has three soil pits with sensors to measure the volumetric water content of the soil. A tensiometer to measure soil pore-water pressure in the range of +85 kPa to -100 kPa is located at the base of one of the pits. The depth of the instruments in the pit is indicated on the graphs. (all times in UTC)
