Laboratory studies of hydraulics and erosion that result from raindrop splash and shallow flow can be used to test and improve WEPP (Water Erosion Prediction Project) equations. Here, agricultural engineer Dennis Flanagan (left) and soil scientist Stanley Livingston use a green dye to measure flow velocity and observe runoff patterns resulting from simulated rainfall.
