When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...

Bridge databases contain signiicant information that can assist in future bridge management decisions. The eeective utilization of this information requires facilities for the exible extraction of usable knowledge in the form practitioners can use. We propose machine learning technology as a means to perform this knowledge extraction and to support the maintenance of bridge database information...

A series of bridge collapse take place in recent years, which cause people to pay more attention to bridge health monitoring and early warning. An intelligent health monitoring system for bridges is proposed after analyzing the functions and characteristics of the current bridge health monitoring system. The paper first introduce main functions of system and key technologies, then mainly introd...

Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...

Soil and water resources management of rivers has an important role because of direct relation withdifferent systems such as earth, life, social and people. Although the use of vegetation cover inbioengineering and biological stabilization and also soil and water resources management projects hasmany advantages, but improper methods of design and implementation cause hydraulic specificationsof ...
