This is the overall mission of the United States Department of the interior and the United States Geological Survey. The two mentioned departments are responsible for bridges and scours which this paper seeks to discuss. Studies have evidently determined that streambed scours are the leading cause of bridge failure in the United States. This results to approximately 60 percent of all bridge failures. The societal repercussions that are associated with failures and the costs that are linked to repair are amplified in Alaska, alternate routes of ground transportation between several cities are not in existence. Bridge culvert damages cost a lot to the economy, for example, in 2002 the damage in Kenai Peninsula was estimated at about 19 million dollars. This led to bridge site examination for scour. Purpose This paper therefore seeks to discuss pier scour in coarse bed and cohesive materials. The purpose of this paper is very open: to know how scour works and why bridges fall down. This is an issue that everyone could be interested in. Several bridges have been witnessed fall down and it has taken my attention to study how the whole process takes place. ...
