Experimental Study on Scour around a T-Shaped Spur Dike in a Channel Bend

AbstractThis paper deals with the study of the geometry of the scour hole and topography of the bed around a T-shaped unsubmerged spur dike located in a 90° bend. The experiments were carried out in a channel with a 90° bend. Uniform sediments having an average diameter of 1.28 mm were used under cl...

Description
Summary:AbstractThis paper deals with the study of the geometry of the scour hole and topography of the bed around a T-shaped unsubmerged spur dike located in a 90° bend. The experiments were carried out in a channel with a 90° bend. Uniform sediments having an average diameter of 1.28 mm were used under clear-water scour conditions. The effects of parameters like the length of a spur dike, the wing length of a spur dike, the location of a spur dike in the bend, the radius of bend, and flow intensity on the scour around a T-shaped spur dike were investigated. A new equation for scour parameters at a T-shaped spur dike is developed.
