DESCRIPTION:A staged approach for culvert detection in Elevation Derived Hy
 drography is presented using YOLO and Sky View Factor imagery. The first s
 tage infers culvert locations\, followed by stream network modeling in GRA
 SS. Computational benchmarking evaluates efficiency on large LiDAR dataset
 s.
