Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters  on the pattern of distribution of average velocity  and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...

One of the main reasons for bridge failure is local scour at abutments. Laboratory experiments, under clear water condition, were carried out to investigate reduction around vertical abutment by adding one upstream spur dike. Sand with a median and standard deviation diameter equal 0.80 mm 2.173 respectively, formed bed material. Three different stages dikes varying sets as: 1) distances from (...

Fishbone-shaped dikes are always built on the soft soil submerged in water, and foundation settlement plays a key role stability of these dikes. In this paper, novel simple approach was proposed to predict fishbone by using extreme learning machine. The machine is single-hidden-layer feedforward network with high regression classification prediction accuracy. data-driven models were based small...
