TUFLOW HR Output: Difference between revisions

:* High-resolution depth output: The depth is the difference between the interpolated water level and the sub-grid elevation. This is shown in the image on the right.<br>

The advantage of the HR output is that it can retain the sub-grid detail of the terrain information even at a coarse cell size. As compared in the example below, the HR depth output shows a clear flow path even at a 100m grid. However, nicer depth output does not mean reliable hydraulic result. In fact, the 100m cell size is too coarse to produce reliable/converged hydraulic results for any real-world flood model. It's is strongly recommended that the model convergence/benchmarking tests are conducted based on the standard map output. The HR output should be used for presentation purpose only.
