Evaluation of Straight Groins to Protect the Sandy Beaches Using Numerical Modeling

Groins are narrow structures with different length and height which generally made perpendicular to the coastline. This type of structure, parallel to shore to trap sediment in order toprotect the coastline, or decreasing of sedimentation rate or prevent erosion of the sediment reaching the coast parallel to the downstream point, such as a port of entry or are looking for pool design. Height, length and permeability of groins are important factors determining itseffect on sediment transport rate is parallel to the coast. In this research, effects of wave parameter and structural layout on sedimentation rate and flow pattern around straight groins have been investigated
