The accretion areas are located upstream the fishing port of Ghar El Melh which interrupts alongshore sediment transport (0.22-0.66 +/- 0.21 m/year, i.e., 21,309 +/- 1,113 m(2)/year, i.e., 106,546 +/- 5,565 m(3)/year) and around the recent mouth of the Medjerda River because of fluvial deposits and accumulation of sediment transported by drift currents (2.35-3.35 +/- 0.21 m/year, i.e., 4,956 +/- 1,050 m(2)/year, i.e., 24,780 +/- 5,250 m(3)/year). ![]() Morphological changes and both surface and volume budgets along the Mediterranean coastline Sidi Ali El Mekki-Gammarth which is located at the western fringe of the Gulf of Tunis (NE Tunisia) are studied, over the 1887-2010 period, by ancient minute of bathymetry and aerial photographs treated using digital photogrammetric methods and GIS tools. Hence, it is essential have new regulations and sustainable permanent plans for long term uses in the future. The population growth and pressures on using the land in the coastal areas have always continued and will continue in the future. Therefore, coastal landfills in the southern coasts of the Marmara Sea gradually destroy the natural coastal spaces and the coastline also lost its original appearance. However, the coastal areas, which have sensitive ecological features, face with pressures of tourism and urban-based developments due to these landfills in the coasts. Even though irregular settlements in the coastal areas of cities cut off people’s contact with the sea, the solution of filling the coasts was found for the purpose of recreating green spaces in the interest of the public. The coastal bend, located in Lapseki, Gönen, Karacabey and in the south of Kapıdağ Peninsula, still remains to be a natural coastline. The most obvious coastal change was seen to be in the coasts of Yalova, Gemlik, Mudanya and Bandırma. The line that was 521 km in 1984 reached 560 km in 2011. The study also reached a conclusion that mining sand was effectuated in an area of 1,15 km² and thus the coast was pulled back. According to the result of the study, an area of 5,76 km² have been filled between Çanakkale-Çardak and Yalova within 27 years of time between the years 19. Geometrical confirmation of satellite images were effectuated by using software and techniques of Erdas Imagine 10 and ArcGis 10 and then the coastal analyses from the obtained coastlines and land examinations have been conducted. ![]() Therefore, old and new coastlines have been determined by using Landsat TM images with 30m resolution from the years 1984, 20 as well as colorful orthophotographs of the year 2008 with 0,45 cm resolution. ![]() Owing to the fact that determining the temporal change at the coastline is highly significant in maintaining sustainable coastal development plans, this study focuses on the temporal coastline change in the south coasts of the Marmara Sea, which is one of the seas where coastal use and change are the most obvious.
