Rainfall is measured at the monitoring site using tipping-bucket rain gauges that measure 0.2 mm of rainfall per tip. One rain gage is installed on a bare open slope. A second rain gage is installed beneath the canopy of recovering vegetation.
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.
A laser-distance meter is mounted over the channel to measure the height of flow if present.
Battery voltage is monitored for identifying any problems with battery charging due to solar panel or battery failures.
