A vibration-based bridge scour monitoring technique
Historically, the most common cause of bridge failure has been “scour” – the gradual erosion of soil around bridge foundations due to rapid water flow. A reliable technique to monitor scour could potentially guide timely repair and, in turn, mitigate the risk of future scour-induced bridge failure. …

A SHM-based decision support system for risk management of bridge scour
Flood-induced scour, the erosion of material around bridge foundations due to flowing water ,is by far the leading cause of bridge failures worldwide. Although recent developments in sensor technology have resulted in more structures being monitored, practical applications of scour monitoring …

Smart rocks for bridge scour monitoring -- Design and localization using electromagnetic techniques and embedded orientation sensors
<p>"River bridge scour is an erosion process in which flowing water removes sediment materials (such as sand, rocks) from a bridge foundation, river beds and banks. As a result, the level of the river bed near a bridge pier is lowering such that the bridge foundation stability can be compromised, …

Remote sensing and localization of smart rocks with orientation-controlled magnets for real-time monitoring of bridge scour and riprap effectiveness
… for real-time monitoring of the maximum scour depth and the effectiveness of riprap mitigation measures. A smart rock is one or more stacked magnets encased in concrete that can automatically roll to the deepest point of a scour hole around a bridge pier and provide its location through …

Scour at the Base of Hydraulic Structures: Monitoring Instrumentation and Physical Investigations Over a Wide Range of Reynolds Numbers
Hydraulically induced scour of the streambed at the base of bridge piers is the leading cause of bridge failures. Despite the significant scientific efforts towards the solution of this challenging engineering problem, there are still no reliable tools for the prediction and mitigation of bridge …

The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004)
… used as open ocean boundary conditions for local bridge scour models. At present, very little information is available on the effect that tidal inlets have on these open coast storm tide hydrographs. Furthermore, current modeling practice enforces a single design hydrograph along the open coast …

Multi-Failure Mode Risk Assessment of the Houston/Galveston Bridge System to Hurricane Threats
… area hurricane risk assessment of bridges for multiple failure modes: bridge deck uplift and bridge scour. Due to recent hurricane damage of bridges, emergency managers need to understand the potential state of the bridge network immediately following a storm for effective …

Magneto inductive communication system for underwater wireless sensor networks
… underground infrastructure monitoring, such as bridge scour and levee scour monitoring. The designed MI sensor node combat the directionality of the single coil MI communication by utilizing 3D coil to both transmit and receive. The presented MI sensor node is tested in air and underwater to …

Seismic Vulnerability Analysis of Scoured Bridge Systems
Bridges are a vital infrastructure component of the transportation networks in both rural and urban areas. Damaged or destroyed bridges can affect the reliability and resilience of transportation networks that are critical to human life, economical activities, and the social sustainability at …

Conceptual, algorithmic, and statistical exploration of relations between runoff generation, stream geomorphology, and watershed topography in West Texas
… in an Ephemeral Stream: A Case Study in Bridge Survival (Republished with permission of the Transportation Research Board.) A case study concerns a small bridge site in an arid area where ongoing inhibition of the transport of bed load sediment has caused chronic problems and maintenance …

Erosion behavior and scour risk of extremely coarse streambeds
Bridge scour, which is the erosion of soil and rock around bridge abutments and piers, is the principal cause of bridge failure in the United States and around the world. Previous investigations of scour have focused mostly on fine sediments such as sand, silt, and small gravel, because such …

Experimental Investigation of Turbulent Flows at Smooth and Rough Wall-Cylinder Junctions
… to turbomachinery and electronics to bridge hydraulics, a number of phenomena (drag, heat transfer, scouring) are driven by the behavior of the most prominent feature of junction flows: the horseshoe vortex system (HVS). Focusing on turbulent flows, the complex dynamics of the HVS is …
