| Summary: | The research presents a techniques for natural hazard assessment using GIS
and cartographic approaches with multi-hazard mapping in urban communities,
because natural hazards are a multi-dimensional phenomena which have a
spatial component. Therefore the use of Remote Sensing and GIS has an
important function and become essential in urban multi-hazard assessment. The
first aim of this research was to determine the geographical distributions of
the major types of natural hazards in the study area. Seismic hazards,
landslides, rockfalls, floods, torrential floods, and excessive erosion are
the most significant natural hazards within the territory of Banja Luka
Municipality. Areas vulnerable to some of these natural hazards were singled
out using analytical maps. Based on these analyses, an integral map of the
natural hazards of the study area was created using multi-hazard assessment
and the total vulnerability was determined by overlapping the results. The
detailed analysis, through the focused research within the most vulnerable
areas in the study area will highlight the administrative units (urban
centres and communes) that are vulnerable to various types of natural hazard.
The results presented in this article are the first multi-hazard assessment
and the first version of the integral map of natural hazards in the Republic
of Srpska.
