Flood events in the coastal zone of the eastern part of the Black Sea region, Turkeyپنجمین کنگره بین المللی جغرافیدانان اسلام
Floods are one of the widespread natural disasters, and cause significant loss of life and property in the world and Turkey every year. The aim of the paper is to explain happening of floods in the Eastern part of the Black Sea Region, and to discuss preventive measures for floods from point of geographical view.The study area has mild Mediterranean climate which is temperate and humid. Mean annual temperatures change between 14 –15 0C near the shoreline. Mean annual precipitations are high, and especially of the eastern part of the study area exceeds 2000 mm at Rize (2333.2 mm). The slopes in the study area are very steep, and the main bedrock is usually composed of volcanic materials. The thicknesses of soils and debris materials aren’t much, and are usually moist. On the other hand, the settlement units are scattered on these slopes and their sewage water problems have tried to be solved with cesspools. So the soils around them are usually saturated with water. For that reason, heavy rains can cause flash floods. On the other hand, untouched areas rapidly decreased due to population growth in the coastal stripe in the last years. The buildings are generally built on slopes, and an important part of them have not sufficiently infrastructure. The solution of the problem is possible only multidisciplinary approach. For that reason it must be quickly made a regional plan, and everyone nicely act to this plan and the relevant laws.<\div>
