Evaluation of Relationship of Spatial Planning-Georisks and Urban Risk Analysis: The Case Study of Bartin
While Turkey is located on a geography having the natural hazards which cause disasters such as earthquake, flood, landslide and the like, a lot of settlement areas are exposed to the risks on various levels caused by these hazards. The spatial planning approach including urban risk evaluation studies for the identification of previously the hazard occurring risks and the detection of the damage levels will help to reduce the losses which will be occurred by the negative social and economical effects of the disaster-sensitive planning approach. The urban planning should be designed as the problem solver and dynamic process to create the healthy, safety and survival urban environment, and the risk decreasing measurements should be necessary in the planning process. In a study carried out in this period, the evaluation related to the geoscientific data was performed on the identification of the disaster risks for the urban planning by the risk analysis method and the least diminishing of the disaster harms by the measurements taken in the planning period. As the sample area, Bartin city was chosen because it includes the earthquake, flood and over flood together. The urban risk evaluation caused by the geological factors in Bartin city was tackled by the analysis input creation for the disaster- sensitive planning approach and disaster risk management. The urban disaster risk and damage level were assessed by analyzing GIS for each risk factor and land use decisions and by relating to the regulatory development plan covering the available land uses of the city to the complied geoscientific data.
