Abstract
Coastal erosion impinges directly on many aspects especially tourism sector. Due to this problem, a study was carried out at Kampung Sungai Lurus shoreline to determine sediment shear stresses and characteristics of sediment load. Parameters needed were oceanography data and characteristics of sediment load. Sediment shear stress, τo was calculated by Prandtl-Von Karman equation and critical shear stresses, τc were figured by using Smerdon and Shield method. Results figured that sediment shear stress, τo value is 21.76 '/m2, while Smerdon and Shield method gave 1.92 '/m2 and 0.0251 '/m2 respectively. Both methods showed sediment shear stress were greater than critical shear stress (τo > τc). It shows that erosion happened at this area. Besides of regular maintenance, soft engineering techniques were suggested to attenuate and dissipate wave energy at shoreline.
