An article by Saengsupavanich, Ariffin, Yun, and Pereira, summarises and critically reviews beach morphology environmental impacts. The aim of the article is to manage coastal erosion with breakwaters to help coast practitioners to be sustainable in this field. Coastal zones have a value to human services and needs such for tourism, fishery industries, shipping, economic benefits, and protection against floods. The coastal zones are, however, susceptible to climate change as they are vulnerable to storm surges, cyclones, sea-level rise, and flooding. The article looks into various outputs such as: hydrodynamics, coastal tourism, notable effects, beach morphology, ecology and recreation. This research that is being carried out is to assist coastal practitioners to utilize breakwaters sustainably. There is still a debate on whether submerged and emerged breakwater are effective and reliable as there have been success stories but also criticisms. The aim of the study is to create an awareness to coastal practitioners on ways to reduce environmental disturbances and to manage coastlines sustainably. A method of protecting or implementing shoreline defense is through emerged or submerged breakwaters.
