Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, ...
The same woman becomes more attractive when meeting on the exciting suspension bridge. Donald Dutton and Arthur Aron's study (1974) [3] to test the causation of misattribution of arousal incorporated an attractive confederate woman to wait at the end of a bridge that was either a suspension bridge (that would induce fear) or a sturdy bridge (that would not induce fear).
One bridge was a very scary (arousing) suspension bridge, which was very narrow and suspended above a deep ravine. The second bridge was much safer and more stable than the first. At the end of each bridge an attractive female experimenter met the [male] participants.
Hydrodynamic scour is the removal of sediment such as silt, sand and gravel from around the base of obstructions to the flow in the sea, rivers and canals. Scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure.
Hydrodynamic scour, the removal of sediment such as sand and silt from around an object by water flow Bridge scour, erosion of soil around at the base of a bridge pier or abutments via the flow of air, ice, or water; Tidal scour, erosion of substrate via tidal flow; Ice scour or ice gouge, a drifting ice feature that scrapes the seabed
Bridges may collapse due to bridge scour around one or more bridge abutments or piers. In 2004, the remnants of Hurricane Frances, and then Hurricane Ivan, caused a large number of washouts in western North Carolina and other parts of the southern Appalachian Mountains, closing some roads for days and parts of the Blue Ridge Parkway for months.
The Los Angeles River is extensively channelized with concrete embankments.. River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit.
Tidal scour can be determined by looking at the change in bathymetry over time. Bathymetry of tidal channels is determined using multi-beam sonar or LiDAR. By comparing cross-sections of channel bathymetry over several years and at various distances in the tidal channel, the amount of tidal scour can be quantified. [2] [better source needed] [4 ...
