Abstract

In the present study, Groynes are flood controlling structures that protect the riverbanks from erosion and also regulate the stream flow. The presence of groynes in the river flow has a major effect on hydraulic parameters such as water discharge, velocity, turbulence, and sediment thickness. The spacing between each groyne, the width and length of the groynes are all significant factors in groyne design. The length of the groynes should not exceed 25% of the river's width; if they are, the river's flow discharge will be reduced. The groynes, if spaced sufficiently between each spur dike, control the turbulent currents of the water flow. Physical experiment methods on the flume provide information on factors such as point velocity, flow depth, bed formations, and other important parameters throughout the channel length. We can determine the Froude number, Reynolds number, point discharge, and other variables using them. When groynes are present on the flume, sediment erosion is reduced when compared to a basic sediment bed. By erecting groynes along the river's banks, scour holes that had previously formed along the river's banks are moved to the tip of the groynes inside the river, avoiding scouring and eroding of the river's banks.
