A: Schematic diagram of Tulane Delta Basin facility. Positions of topographic transects in TDB-10–1 experiment are indicated by black dashed lines on fluvial surface. Note that base-level control is in opposite corner of basin from infeed point. B: Photograph of active delta top at 10.2 h run time. C: Synthetic stratigraphy for proximal laser transect generated through stacked delta-top profiles with topography clipped to account for sediment removed during erosional events.

Schematic of experimental setup and maps illustrating types of data collected over the course of each experimental stage. A) Schematic diagram of Tulane Delta Basin with key basin dimensions and controls labeled. B) Characteristic digital image of the HMSP stage with flow on and dyed for visualization. Image collected with laser scanner such that all pixels are referenced relative to the basin coordinate system. Locations of physical stratigraphic sections are shown by solid black lines. C) DEM of experimental surface collected with laser scanner. Solid white line denotes shoreline. Dashed red line shows the extent of DEMs where topography was reliably measured for each run hour.
