Sažetak:
Split case study comprises areas exposed to both flash floods and rock-falls. Areas directly exposed to flash floods are mainly related to Cetina river watershed while areas endangered by rock-falls are two limited areas: town of Omiš and area in the municipality of Duće. The paper shows a methodology for hazard assessment for both phenomena. The hazard assessment for flash floods is based on the measured data and other spatial information and/or analysis provided by GIS. The methodology takes into account European Flood Directive. The criteria for the hazard of flood assessment are based on the available, collected and processed data. Use of satellite remote sensing data enables DEM analysis (topography, geomorphology, flow accumulation, land use and vegetation), whereas traditional collected data give information on hydrology, meteorology, geology, infrastructure, human settlements and historical record. A preliminary hazard map based on water depth has been evaluated for Sutina- Karakasica part of the watershed. Since spatially distributed assessment of rock-fall hazard is a difficult due to high uncertainty and lack of exact mathematical methods for calculation of rock movements the main principle for the proposed methodology is based on GIS and results from more detail geodetic measurements such as Terrestrial laser scanning (TLS) or satellite remote sensing. The criteria for the hazard of rock fall assessment are mainly connected to geology, geomorphology and topography (slope angle, approximation of mass of the potential loose blocks, cracks distribution) and meteorological data (precipitation, temperature fluctuations). Traditional integrated development planning information such as structure of endangered base of rock fall slope (infrastructure, settlements and historical record) is another significant criterion. A preliminary hazard map based on abovementioned criteria has been developed.
