Scour is the number one cause of bridge failure in many parts world. Considering lack reliability existing empirical equations for scour depth estimation and complexity uncertainty as a physical phenomenon, it essential to develop more reliable solutions risk assessment. This study introduces novel AI approach early forecast based on real-time monitoring data obtained from sonar stage sensors i...

Scour is a phenomenon that occurs as a result of natural erosion by ground water flow and transport of seabed material. In this research, scour around the legs of marine structures is simulated using the FLOW3D.V.9.3™ commercial software. The general scour model consists of two components, namely, the lift and thrust forces. The drag force, that is inserted to the structure, is a combination of...

application of structures of flow pattern modification is one of the erosion control methods in bends. triangular vanes are among these structures which provide less scour depth compared to the other techniques such as spur dike. since little information on erosion and sedimentation pattern around triangular vanes are available, this study was conducted to study the effect of structure effectiv...

Abstract Scour depth estimation is an essential factor in water-related engineering problems. Scouring below spillways may endanger a dam's stability and even lead to dam destruction. As result, it has undesirable environmental effects due failure. Hence, reliable accurate scour exciting topic for researchers. For this purpose, the published prototype data related ski jump bucket (Ds) was used ...

Artificial neural networks (ANN’s) are associated with difficulties like lack of success in a given problem and unpredictable level of accuracy that could be achieved. In every new application it therefore becomes necessary to check their usefulness vis-à-vis the traditional methods and also to ascertain their performance by trying out different combinations of network architectures and learnin...

Local scour around bridge abutment is a common problem encountered worldwide. Extensive laboratory and field studies have been carried out in this field and the equations derived so far are applicable to particular circumstances only. This paper presents an alternative to the empirical equations for Prediction of Local Scour at Vertical Bridge Abutment in the form of genetic programming (GP). T...

Failure of the bridges due to local scour around their piers can cause serious life losses and property damages and create significant environmental problems. In this experimental study, scour hole geometry around circular bridge piers were investigated. The experiments were carried out in a rectangular flume 80 cm wide, 18.6 m long and 75 cm high by using uniform sediment with a median diamete...
