Study area takes place in coastal line of Enez-Kesan districts starting from Dalyan Lake region which was also legally declared as wetland conservation zone of Maritza basin. In this study, nearly 56 km of coastal development in Enez - Kesan, located northern part of Saros Bay, is evaluated according to the ecological threshold analysis. Despite the ecological and socio-cultural importance of the region, transformation of the ecological quality is getting more noticeable. Mapping of Morphological structure are performed from General Directorate of Soil and Water surveys including Slope, Erosion and Land Use Capability Classification data. Furthermore, anthropogenic effects (industrial and residential zones etc.) and natural areas (forestry, wetlands etc.) are determined using SPOT 5 imagery acquired in 2006. The methodology involves covering the study area with grids and potential land evaluation charts. These charts are assessed by "Usage Value Analysis for Supporting Method of Planning" and obtain total usage value of the lands. Adverse effects on natural potential lands depending on current land use at the study zone appraised for strategic environmental assessment. Study is aimed to analyze development dynamics and natural thresholds affected by physical geography in coastal line of Enez Kesan districts including also wetlands, natural areas. Study indicates proposals according to the landscape assessments. Additionally, legal tools applied on the study area are provided to pose the effects of legal impediments and to establish the question of law. (C) 2015 Elsevier Ltd. All rights reserved.
