Arc Surveying & Mapping, Inc. working with the Department of Transportation, developed the scour surveying program to monitor underwater conditions at bridge foundations and support structures.
To identify and monitor scour-prone bridges, a baseline survey is performed at each bridge, identifying the existing above and below-water conditions with close detail regarding sediment elevations at each support.
After strong water movement events such as excessive flows caused by hurricanes, heavy rain, and tidal events, a second survey is performed. Isopachs are generated comparing surveys, and scour is identified by color coding scour elevations red - immediately bringing scour to the attention of the client.
In addition, sediment movement quantities are calculated, from which the need for countermeasures may be determined. During post-storm scour surveys, exposed cables, pipelines, sunken vessels, and debris are observed and identified on maps.
