Sažetak
Landslide inventory mapping in the hilly area of the Zagreb City is one of the key objectives of the Japanese-Croatian five-year scientific joint- research project ‘Risk Identification and Land-Use Planning for Disaster Mitigation of Landslides and Floods in Croatia’. Landslide mapping will aid development of guidelines for use in urban planning in the City of Zagreb. In order to make reliable maps that predict the landslide hazard and risks in a certain area, it is crucial to have insight into the spatial distribution and temporal frequency of landslides. Therefore, each landslide hazard or risk study should start by making a landslide inventory that is as complete as possible in both space and time. System of archiving data about neither landslide events nor landslide damages has not been established until today in the City of Zagreb. Existing landslide inventories and landslide susceptibility maps financed by the local governmental authority are shortly presented in the paper: landslide inventory and susceptibility mapping in scale 1:10000 compiled by geotechnical consultancy company ‘Geotehnika-Geoexpert’ in 1979 ; and landslide inventory mapping in scale 1:5000 compiled by Croatian Geological Survey in the period 2005-2007. Areas encompassed by landslide mapping in 1979 and in 2007, as well as methodologies of collection of landslide data and landslide distribution, are analyzed for the purpose of getting insight into quality of existing systematic collections of historical data. It is shown that only some of the landslides in the study area are dated and only for some of landslides is possible to find historical documents describing their initiation. Additional historical data about the most of the investigated landslides are systematically collected from geotechnical reports. On the basis of those data, some conclusions are made regarding ranges of landslide dimensions and types of landslide causes. Moreover, landslide models in the software ADCALC3D are made for few typical landslides to illustrate landslide in 3D.
