The identification of flood vulnerability consists of two basic phases. Firstly, the effective factors causing floods are identified. Secondly, approaches to multicriteria analysis (MCA) in a geographical information system (GIS) environment are applied and these approaches are evaluated in order to prepare a flood vulnerability map. In the analyses, the main causative factors for flooding in a basin area are taken into account, such as soil type, daily precipitation, land use, size of the catchment and basin slope. A case study of flood vulnerability identification in the Bodva river basin in eastern Slovakia is presented in the paper.
