This AR Sandbox setup is mounted on a rolling frame that was built to go over the Emriver 3 stream table. It can be set up to scan an area that is approx 2x3 feet within the table. We intend to use it for change detection (capture screen before/during/after) in landform or channel creation. For example, the changes in meandering stream sinuosity, or delta sediment distribution.

You can read about the software and hardware setup at the Keck CAVES project (Oliver Kreylos at UC Davis) here: https://web.cs.ucdavis.edu/~okreylos/ResDev/SARndbox/ I've attached a PDF with (most) of the info to build ours, but there are probably better ways to design it! Happy to discuss any of the items here.
