Abstract
Coastal vegetaion consists of rooted flowering marine plants that provide a variety of ecosystem services to the coastal areas they colonize. The attenuation of waves and sediments stabilization are often listed among these services. From this point of view, artificial vegetation model is an effective method of controlling sea bed and stabilization without damaging the landscape or the stability of the coastaline. In this study, numerical and hydraulic physical test for predicting deposition proces of a navigation channel caused by wave action is proposed. In the numerical model, we develop a numerical model for describing the wave attenuation and sediment transport in a navigation channel with a vegetation area. In addition, hydraulic model tests is performed in a navigation channel with irregular waves to examine the effect of vegetation in relation to deposition reduction in navigation channel. A comparison between the results of hydraulic and numerical tests shows resonable agreement.
