Instrumentation Capabilities

In order to perform state-of-the-art research in hillslope hydrology, equipping experiments with an array of instrumentation and sampling techniques allows us to assess water movement over, into and through these experimental landforms.  The MOST facility has aquired a vast array of instrumentation to assess many parameters.

In-Situ Measurements Laboratory Based Measurements

Soil Moisture


Soil-water tension

Small and Large Scale Hillslope Testing

The MOST facility currently operates two sizes of testing beds, our small-scale slopes are 0.63 m wide, 1.78 m long and 0.43 m deep. 12 are available for replicate testing.

We currently operate 2 large scale hillslope test beds that are 4 meters long, 2 meters wide and up to 1 meter deep. Pricing information is based on a la carte experimental requirements, however starting prices are listed below.

Small Scale (mini) Hillslope $100/ week
Large Scale Hillslope $600/ week
