Tool [deprecated] Lake Flood
Note: this tool is deprecated and will be removed in one of the next SAGA versions. It has been replaced by the more robust and powerful 'Terrain Flooding' tool.
This tool can be used to flood a digital elevation model from seed points. Seed points have to be coded either with local water depth or absolute water level.
