Why develop and benchmark models to support uncertainty analysis? Two-dimensional models of floodplain hydraulics require a lot of computation time. Increasing resolution requires increased computation. Monte Carlo… also increases computation Simple models: Require less computation per time-step than a shallow water models. Force modellers to think about the minimum process representation necessary to predict particular quantities. Are generally not as widely applicable as shallow water models – thus we need to understand their limits. Some may require shorter time-steps to remain stable especially at 1-10 m resolutions (Hunter et al., 2005).

Results – Valley filling following dam failure

The frequently of velocity output had as much impact on hazards assessment as model physical complexity.
