Natural hazard management in regional base using geographical information system
Reis, Selcuk, Volkan Yildirim and Halilibrahim Inan
Today, one of the crucial issues in regional development is the management of the natural hazards for planning and controlling in a sustainable manner. Turkey is one of the countries that are under the high risk of natural hazards due to its tectonic activities, geological structure, topography and meteorological features. In the country, every year various types of natural hazards have been observed frequently. Among these earthquake, flood, landslide, avalanche and rock falls are the most common ones. The most important natural hazard in the Eastern Black sea Region of Turkey is the "landslides". In Trabzon province which is located at the NE of this region there are also unfavorable conditions on environment such as climate, topography and land cover. According to records kept since 1950 in Turkey, there have been observed 272 land slide occurrences in Trabzon, one of the leading areas where landslides occur mostly. Besides same environmental factors in the region cause settlement areas to be restricted. Therefore, to decrease the landslide risk and to plan suitable urban areas at regional level, firstly, potential landslide areas should be determined, then "suitable settlement areas" should be recommended accordingly considering these areas. The most common techniques realizing these studies are Geographic Information Systems (GIS) and Remote Sensing. In this study, GIS functions were used for analyzing the regions that are subject to natural hazard risk and suitable for settlement in high scale planning.
