Line 159:
As per Test Case 1, selection of the appropriate cell resolution during a real-world project requires consideration of the intended use of the results and also how the simulation times impact on the overall project timeline.
* Detailed integrated 1d/2D urban modelling may adopt the 15ft or slightly finer 12.5ft cell resolution if the cumulative simulation time for all model events/scenarios does not adversely impact the project timeline. This timeframe consideration is particularly relevant in locations such as Australia where an ensemble methodology is currently replacing single event approaches as a way to address uncertainty associated with hydrologic assumptions.
* Broad-scale quick run simulation for urban flood forecasting purposes may adopt a coarser 20ft cell resolution to achieve a quicker simulation turnaround time.
