wrcr13623-sup-0002-S01.epsPS document590KFig. S1. Digital elevation model for high resolution test case. The inflow point is at 0, 250 m (top of channel). Dots show control points 1-3.
wrcr13623-sup-0003-S02.epsPS document1020KFig. S2. Wave propagation through test case over time, plotting results from the high resolution model, a model at 1/5th of the resolution without the channel and a subgrid channel model.
wrcr13623-sup-0004-S03.epsPS document730KFig. S3. (a) Plot of inflows to model domain and outflows from the domain for the three models. (b) Plot of residuals between outflow discharges from the high resolution model and the low resolution model with and without subgrid channels.
wrcr13623-sup-0005-S04.epsPS document1044KFig. S4. (a, c, e) Plots of simulated levels from the three models at the three control points shown on Figure S1. (b, d, f) Plots of residuals between high resolution model and subgrid model, results from the low resolution model are not shown because of the large magnitude of the residuals relative to the sub-grid model.
