"The removal, transport, and deposition of soil by wind, also known as wind erosion, has long been a problem that has plagued mankind." - A History of USDA-ARS Wind Erosion Research at Manhattan, Kansas 1947-2005 by John Tatarko.

ARS technician H. Lagae works on the rain simulator used to simulate the effect of rain on soil surface crust formation.


The Wind Lab's greenhouse.  Soil samples are air dried before performing various experiments.


ARS Engineering Tech M. Kucharski places soil trays on drying racks.


ARS biological science aid A.  DeMaranville puts soil samples into a rotary sieve to learn the "Aggregate Size Distribution (ASD)" of a given soil - an important property of soil.


M. Erdwien, Engineering Tech, uses an analytical scale to weigh filters that capture dust emissions.


An experimental laser is used to calculate the random roughness of a soil sample tray.


Engineering aid N. Baker places soil sample tray in the outdoor wind tunnel.



Each tray has different treatments and are then tested for soil loss and emissions. The wind turbine is at the far end of the tunnel.



Engineering Tech H. Lagae powers up the large indoor wind tunnel turbine.  The indoor tunnel's cross sections measure 8 feet tall and 5 feet wide and is used to test various terrains and soil treatments.
