Overwash experiment GIF – continuous scanning @saflumn @stcNCED
Sneak preview of a forthcoming animated feature. Below is a sequence of topographic scans taken from a single run. Data are a bit raw, but they still offer a sense of how active the berm could be. One pass with the laser along the three meter length of the berm required five cross-shore swaths (here shown stitched together) and just under two minutes to complete.
In this trial, the berm crest is 2 cm higher than the back-barrier platform, and the “storm surge” is a constant discharge of 0.3 l/s.
