Sažetak
Project „Risk Identification and Land-Use Planning for Disaster Mitigation of Landslides and Floods in Croatia“ was submitted on the international call of the Government of Japan for scientific research projects in 2008 as one of 10 projects in program Science and Technology Research Partnership for Sustainable Development financed by Japan Agency for Science and Technology-JST and Japan International Cooperation Agency-JICA. Japanese partner institutions in the Project are Niigata University (The Research Center for Natural Hazards and Disaster Recovery), Kyoto University (Disaster Prevention Research Institute, DPRI) and International Consortium on Landslides (ICL). Croatian partner institutions in the Project are University of Rijeka (Faculty of Civil Engineering), University of Zagreb (Faculty of Mining, Geology and Petroleum Engineering and Faculty of Agriculture) and University of Split (Faculty of Civil Engineering, Architecture and Geodesy) and Croatian Geological Survey. Predicted duration of the project is five years. The main activities of the research groups involved in the Croatian–Japanese joint research Project include investigations of recent landslides using landslide monitoring, the establishment and development of early warning systems for landslides, flash-flood and debris-flow simulation models, development of early warning systems adapted to hydrological and geological conditions in Croatia and the definition of hazard zones using a methodology for assessing susceptibility and hazards based on local geological and landslide conditions. The final objective is the development of risk mitigation measures that can be instituted through urban planning. In the framework of the Working Group on Landslides (WG1) a systematic monitoring in real time, laboratory analysis of soil samples and numerical analysis of the behavior of landslides in static and dynamic conditions on the landslide Grohovo and landslides Kostanjek in the City of Zagreb are carried out. Working Group for Flash-Floods and Debris Flow (WG2) conduct observations of meteorological and hydrological parameters in the analyzed catchment areas in real time ; numerical and hydrological analysis of the measured parameters ; and the development of simulation models of floods, mud flows and flow, making an early warning system on these phenomena. Selected research areas are in the vicinity of Rijeka and Split. Activities of Hazard Mapping and Land-use Guidelines Working Group (WG3) included the development of inventory of landslides using remote sensing techniques and methods of analyses and hazard zoning. Japan-Croatia workshop - Risk identification and land-use planning for disaster mitigation of landslides and floods in Croatia was held at the University of Niigata in February 2010. In November 2010 the 1st workshop of the Project was organized with the aim of disseminating the project results among the members of the project, but also scientists from other institutions in the region in Dubrovnik, and the 2nd Workshop in December 2011 at University of Rijeka. The workshops will contribute to the establishment and development of regional cooperation, which is important for the sustainability of project results even after the project ends in March 2014. Concerning the components on landslide risk assessment, aerial photos and aerial laser scanning images were purchased for selected target areas and landslide risk areas are identified by the interpretation of landslide topography using those photos and images. A portable ring shear apparatus was newly developed and essential shear strength parameters for prediction of travel distance of sliding soil mass for a Kostanjek landslide area in Zagreb was measured using this apparatus. A comprehensive landslide monitoring system using GPS, Total Station, extensometers, inclinometers was installed in Grohovo landslide area near Rijeka. Furthermore, dynamic simulation of landslides and debris flow was carried out on Rječina River valley including Grohovo landslide area. Concerning the components on flash flood risk assessment, systematic observation systems of meteorological and hydrological parameters were installed in selected target river basins such as Dubračina river and Mosčenićka Draga river. On the basis of real time monitoring results in those river basins, hydrological analyses were conducting. Essential tools for the next step of the project were prepared. Results of individual analyses will be appropriately combined for formulation of integrated landslide-flood hazard maps.
