Replication Data for: "Sediment load determines the shape of rivers"

Measured depth and sediment flux profiles for experimental laminar rivers described in P Popovic, O Devauchelle, A Abramian, and E Lajeunesse (2021), "Sediment load determines the shape of rivers", PNAS, accepted. The data were originally collected by A Abramian, O Devauchelle, and E Lajeunesse (2020), "Laboratory rivers adjust their shape to sediment transport", Physical Review E, 102(5), 053101.

Dataset consists of five experiments with varying sediment discharge. For each experiment, we provide a depth profile (experiment_X_depth.csv) and a sediment flux profile (experiment_X_sediment_flux.csv).

experiment_X_depth.csv contains three columns:
y[cm] - transverse coordinate in cm;
D_raw [cm] - raw measurement of depth in cm;
D_smooth [cm] - smoothed depth in cm used in the analysis in the paper.

experiment_X_sediment_flux.csv contains two columns:
y[cm] - transverse coordinate in cm;
qs [grains/cm/s] - sediment flux in grains/cm/s.

The sediment discharge (in grains/s) for each experiment is provided in sediment_discharge.csv with the corresponding uncertainties provided in sediment_discharge_std.csv. Experimental parameters and their uncertainties are summarized in parameters.csv and parameters_std.csv.
