This paper examines the coastal regional trends in urbanization processes using remotely sensed
images around the Kucukcekmece Lagoon as a case study, located in the western part of Istanbul, Turkey. Throughout
the examination process, the coastline changes are determined for a long-term period. To achieve this goal, postclassification
comparison method is applied to the CORONA and LANDSAT TM satellite images of 1963, 1987 and
2005. In order to identify the land use changes, common landscape structures in the region were distinguished as water,
green and open land, urban and industrial areas. Due to the mix up of land-cover types between urban and industrial
areas, the classified images are integrated with geographic information system data obtained from visual interpretation
of the enhanced images and auxiliary data sets. The results of the change analyses in coastal region showed that
important alterations are taking place in the area due to the unplanned urban and industrial expansions that has
irreversibly changed the physical features of the Kucukcekmece Lagoon. According to image classification results, the
urban land use area increased from 2 % of total area in 1963 to 38 % in 1987 and 46 % in 2005, most of which converted
from agricultural and greenlands. At the same time, the ecological impact of the loss of specific land covers is highlighted
based on the results of the land use changes and the previous scientific applications. Furthermore, some recommendations
are given to planners, decision makers and politicians to maintain the sustainable coastal ecosystem management.
