Orthometric Height vs Ellipsoidal Height
Technical Details & Mathematical Formulation
Water flows according to gravity and orthometric height, not ellipsoidal height. In civil engineering and flood modeling, GPS heights (h) must always be converted to orthometric heights (H) using high-resolution geoid models like EGM2008 or GEOID18.
