FloodingLakeSystem Node
Simulates lake formation on a terrain by filling topographic depressions. The algorithm analyzes the terrain elevation model, detects enclosed basins, and incrementally floods them to estimate lake water depths and extents. It applies a depression-filling method to determine the resulting water surface elevation.
