Estuaries worldwide have very different morphologies and respond differently to sea level rise. A classification system has been developed for tidal bars similar to classifications for rivers. We found that the estuary bathymetry, average velocities, the depth, the bar pattern (and much more) can be predicted from basic boundary conditions and estuary planform outline, even when no other data is available. Modelling showed that smaller estuaries have a risk of increased high flood water levels with sea level rise, while larger estuaries have a risk of sediment starvation.
