Hydrologic-Enforcement of Lidar DEMs
Detailed Description
Surfaces showing topographic elevation surface with road fill over a culvert (left image) and hydrologic elevation surface with hydrologic-enforcement at the drainage structure (culvert) location.

Hydrologic-Enforcement of Lidar DEMs
Hydrologic connectivity of light detection and ranging (lidar)-derived elevation data is critical for coastal hydrologic modeling applications. However, unless hydrologically-enforced, raised structures (i.e. bridges, roads overlaying culverts) can block overland flow to coastal waters. Because highly detailed lidar-derived elevation surfaces include features such as bridge decks and road fill...
