The excel document contains three tabs: README - provides column descriptions for the remaining two tabs. RawData - Eighteen unique profiles were modelled, with ten runs per profile, for two scenarios: morphological updating enabled, and then disabled. This results in a dataset comprising 360 individual model runs. Each row represents one run as is described in the README tab. Statistics - Calculates the average overtopping discharge (with and without morphological change) for each representative profile. The methodology used to generate this data set is described in: Pollard et al. (2021).
