Shear Stress Impact on Coastal Water Defense Structures in Asaba River Niger Waterways

Abstract

This work serves as a useful tool for the design and redesign of new and existing coastal structures by water engineers in Coastal Engineering works. The Pin technique with relevant models was used in the actualization of the presence of erosion. Surface friction coefficient, wind speeds in the x and y directions, and water density were obtained and used in measuring shear stress in the x and y directions. This was used in understanding the force impact generated from both directions. The resultant values of 233.2047 and 306.8813 respectively were obtained. From the results obtained, it was concluded that shear stress impact was notably observed to be significant in wearing off the coastal structures.
