Table 1. Experimental setup. Experiments are run with and without vegetation.
Table 2. Data for individual triplicate model simulations used to obtain averaged values presented in Figure 1. Shoreline roughness and number of channels are averaged over the second half of the model simulation and presented with standard deviation. LWHSv1 and 2 have no values forM . Both modeled deltas formed lobes to the left side of the model domain during the first half of the run, leaving a large embayment on the right side which fills in during the second half of the run (Figure S1). Because M is calculated only considering channels that were within the delta area at the halfway point of the model run, and for the second half of the runs channels are concentrated on delta area that did not exist at that time, we do not include these values. LWHSv2 has no value for R because the Python Scipy tool “optimize curve fit” failed to find a solution to fit an exponential decay function to the data. This is probably because there was not enough data, for the same reason as we could not calculate M for LWHSv2.
