Wind Blown Erosion Measurement Solutions


Research Erosion Site Equipment Requirements

This research field site configuration would be suitable for basic wind erosion equation development (WEE). The calculation of U* (Ustar, or friction velocity) requires a minimum of three anemometers.  We suggest using four anemometers per site because the probability of one going bad is high.

Never assume everything will simply work fine. Make sure you have recorded (and looked at) test data in the lab before setting up your site in the field. The field environment has few facilities to repair or rebuild.  And more often than not, your data acquisition program may be less than desirable.  

Always have backup anemometers. All anemometer bearings prematurely fail from dust.
