LiDAR has become an established method for collecting very dense and accurate elevation data across landscapes, shallow-water areas, and project sites....
This article discusses defining HEC‑RAS culverts for fish passage, by defining multiple roughness regions and partially-buried culverts. Multiple Roughness Regions...
The culvert computational routines in HEC‑RAS require the same four cross sections as the bridge computational routines. These cross sections include:...
