We observed the incisional response of an alluvial river to base-level fall. We conducted the experiment in a 3.9 × 2.4 × 0.4 m box that we filled with uniform 0.140±0.04 mm sand. We dropped base level by lowering the elevation of an "ocean" pool at the river outlet. As the initial condition, we cut a 10±2 cm wide channel to a steadily increasing depth, from 3±0.5 cm at the inlet, where we supplied water and sediment, to 10±1 cm at the outlet. Input water and sediment discharge were 0.1 L/s and 0.0022 L/s (including pore space), respectively.

These data consist of digitial elevation models of experimental topography recorded at 5 - 10 minute intervals during a series of experiments combining hillslope diffusion and channel incision in a meter-scale eroding landscape. The data were processed from the raw returns of a SICK laser scanner; processing includes noise removal and some interpolation for missing data.
