DeltaVeg - delta experiments with alfalfa

Plants are known to increase sediment trapping and decrease channel mobility on large scales, but their affects on delta grown were not yet understood. We conducted experiments to determine how to create and maintain dynamic channels on a vegetated delta. Experimental deltas are highly depositional by nature, so plants effectively erased channels. Discharge fluctuations were necessary to maintain channel relief. Runs 1-4 have constant discharge, while Runs 5-6 have fluctuating discharge. See individual folder files for experimental parameters. Runs 1 and 5 are control runs with no plants. All experiments are conducted with 170um silica sand, alfalfa for vegetation, and 0.02m basin depth. Data were used in paper https://doi.org/10.1002/2017JF004378. Paper run names and dataset run numbers: NP1 = Run 1 P1 = Run 4 NP2 = Run 5 P2 = Run 6
