Wind Tunnel Experiment (VIDEO)

University of Texas at Austin

Caption

The video file has four sections showing how topography and erosion rates evolve through time in the experiment. Plan-view digital elevation of the crater model (upper left) shows the crater interior going from filled to mounded to empty. A topographic profile of the crater (bottom left) accompanies this and gives the cross-sectional view. On the right are calculated erosion rates in plan view (upper right) and cross-section (lower right). These show how erosion is highest near the crater rim, which creates the moat and mound retreat.
