MIKE Flood to TUFLOW: Difference between revisions

Unlike TUFLOW, the grid cell size of the model in MIKE is determined directly by the input grid file. For more discussion on grid cell size and the differences in how MIKE and TUFLOW handle the underlying terrain please see the <u>[https://wiki.tuflow.com/index.php?title=MIKE_Flood_to_TUFLOW#Discussion discussion]</u> section at the bottom of the page.<br><br>''Note: After grid conversion, it is important to perform checks that the ascii grid has converted properly. This is best done in your preferred GIS package. ''

''Note: A downfall of this method in MIKE, is that elevations in the .dfs2 grid couldmay have been manually modified such that the area outside the flood extent has a constant ‘Land’ elevation. Inspection of the terrain data before use is highly recommended. ''

The Upstream boundary can be digitised in TUFLOW as a 2d_bc (type ‘HT’), or as a 2d_SA polygon. For more discussion on selecting an appropriate upstream boundary type, please see the <u>[https://wiki.tuflow.com/index.php?title=MIKE_Flood_to_TUFLOW#Discussion discussion]</u> at the bottom of the page.
