Abstract Scour is the leading cause of bridge collapse beneath any pier located within waterway. A numerical-based hydraulic model named Hydrologic Engineering Centre River Analysis System and a mathematical Florida Department Transport were implemented to investigate their performance accuracy in estimating maximum scour depth piers where large small-scale physical prototypes are used as bench...
many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...
A scour monitoring system for subsea pipeline based on active thermometry is proposed in this paper. The temperature reading of the proposed system is based on a distributed Brillouin optical fiber sensing technique. A thermal cable acts as the main component of the system, which consists of a heating belt, armored optical fibers and heat-shrinkable tubes which run parallel to the pipeline. Th...
