Unsustainable urban growth has put pressure on urban coastal areas and historical–cultural structures. As such, the important role of coastline sustainability has been revealed, and planners must protect historical–cultural coast characteristics in order to increase the quality of life of citizens. For this reason, this present study investigated the effects of existing coast characteristics and historical–cultural structure changes in recreation and tourism with respect to the Trabzon coastline in Turkey. Through literature and site survey, these effects were classified using specific coastal criteria which increase and decrease coastal use, and these were grouped by factor analysis. For the main criteria, the analytic hierarchy process (AHP) method was used, and for sub-criteria, the Elimination and Choice Expressing Reality (ELECTRE) method was employed, combining multi-criteria decision-making methods to generate a priority ranking for all criteria. Consequently, “socialization”, “city promotion” and “service quality” were revealed as the most effective criteria with respect to coastal use. The methods and the findings may significantly contribute to sustainable tourism planning for other urban coastal areas.

Integrated Multi-Criteria Decision-Making Methods for the Sustainability of Historical–Cultural Structures on the Trabzon Coastline

Dispersion characteristics of air pollutants in the mountainous coastal area are investigated in considering with the mesoscale local circulations using a two dimensional numerical model with two kinds of topograpy of 500m and 300m. In the model, land-sea breezes and mountain-valley wind are mainly considered under the condition of the absence of large scale prevailing flow in the circulation analysis, and the pollutants dispersion is traced by the Lagrangian methods. According to the results, the wind velocity is affected by topography and is stronger in the case of 500m height mountain than that of 300m, the pollutants that source is near the coast transported over the mountain and dispersed to behind inland area. It is classified that the topography change control affects the wind velocity and the circulations. The pollutants that source is different transported and concentrated to behind inland and/or diffused to the sea area by the combination of the wind system with topographic changes. The results can be applied to the air pollution control with the arrangement design of industrial area and the planning of coastal developments.
