Two different shapes of curved groynes, namely as, quadrant (quarter of a cylinder) and semi-parabolic shaped groynes were used to indicate the effect of groyne shape on the local scour generally, scour is decreased about (75) % in quadrant shape groynes as compared with that of semi-parabolic shape groynes. The effects of groyne layout on the flow in numerical investigation of flow hydrodynamics in a channel with a journal of hydraulic research, 52(1. Amplification of near-bed velocity is due to contraction of the channel cross-section and as well as due to local effects of the groyne structure is higher in the case of sd and repelling groyne (rg-45 and rg-60) than that of t-shape groynes.

Recommendations for further studies include the investigation of the effects of different bend radii, the sediment size, as well as various channel widths, flow rates and river slopes the use of a three-dimensional hydrodynamic model would also be advantageous in order to better understand the flow and scour mechanics associated with different. Abstract in some physical model experiments, it is necessary to use distorted models it is difficult, however, to build in an optimal degree of distortion into the models to ensure a closer degree of similarity between the model and the prototype.
