ABSTRACT. Flood vulnerability in Bodva river basin in Slovakia. The aim of the paper is to generate a composite map for decision makers using selected factors, mainly of natural character, causing floods. In the analyses, some of the causative factors for flooding in a catchment area are taken into account, such as soil type, precipitation, land use, size of catchment and basin slope. A case study of flood vulnerability identification in the Bodva river basin in eastern Slovakia is employed to illustrate the different approaches. A geographical information system (GIS) is integrated with multicriteria analysis (MCA) in the paper. The identification of flood vulnerability consists of two basic phases. Firstly, the effective factors causing floods are identified. Secondly several approaches to MCA in a GIS environment are applied and these approaches are evaluated in order to prepared flood vulnerability map.


Keywords: causative factors, floods, geographical information system, multicriteria analysis.
