TUFLOW 2D Cell Size Selection: Difference between revisions

Since simulation time is not a limiting factor in this case selection of cell size only needs to consider the result accuracy. What is appropriate in terms of accuracy is influenced by the intended use of the model. For example, if lot scale assessment of inundation and structural damage risk is required, selection of the 10m cell size may be appropriate. Alternatively, if the model is only intended to inform broad-scale risk, the 50m or 100m cell size may be sufficient.

 

This test case uses a hypothetical urban model. The model encompasses the entire catchment and covers an area of approximately 21miles2 (54km2). Development within the catchment ranges from rural undeveloped in the mountainous upper catchment to dense urban development in the lower catchment. <br>
