Summary:

Explains the behavior of rivers in order to recognize changing conditions associated with unstable streams or scour at bridge foundations that may threaten the stability of the bridge. Provides tips and guidance on what to look for with regard to both stream instability, including lateral instability, degradation, and aggradation, and scour at bridges, including contraction scour, pier scour, and abutment scour. Also covered are plans of action and countermeasures, such as monitoring, flood watches, bridge closures, and river training countermeasures. Additionally, you will find design guidelines for bridge scour and stream instability countermeasures that have been implemented by various Satate Department of Transportations (DOTs) within the United States. Management strategies and guidance for developing a "Plan of Action" to scour critical bridges are outlined, and guidance is provided for sour monitoring using portable and fixed instrumentation.Related products:Waterways & Bodies of Water collection can be found here: https://bookstore.gpo.gov/catalog/environment-nature/waterways-bodies-waterResources related to the topic ofFloods can be found here: https://bookstore.gpo.gov/catalog/environment-nature/natural-environmental-disasters/floodsDams, Canals & Levees resources collection can be found here: https://bookstore.gpo.gov/catalog/science-technology/engineering/dams-canals-leveesBridges & Tunnels resources collection can be found here: https://bookstore.gpo.gov/catalog/science-technology/engineering/bridges-tunnels
