The water model is based on this theory.
The way this is calculated also has impact on practical use-cases. Below are some basics rules that need to be adhered to get a proper result.
Surface Waterways
Waterways are also calculated as 2D surface flow (not a 1D-line). This has several advantages, like interaction with the shoreline and easy loading of geo-data but is also requires a proper setup of the grid and base data to get flow through waterways.
1 The smallest waterway width needs to be at least 6-8x the cell width. So for example a 3m wide waterway channel (shoreline exclusive) needs to have 3/6 (or even 3/8) = ~0,4m grid cells.
- This is because water must be able to flow from cell to cell especially also when the watery runs in a 45 degree angle to the square grid cells.
- When this rule is not adhered the surface theory does not work and a buildup or to lees water can occur.
