Development of landslide data base conceptual model on the basis of historical landslide data from the City of Zagreb and Primorsko-Goranska County

Landslides in Croatia cause significant economic losses, which trend is increasing due to urbanization of hilly areas. There is no national archive about landslides, nor geotechnical archive about landslide investigation reports and remediation designs in Croatia. Moreover, landslide regulation related to preventive mitigation measures of landslide hazard and risk exist only in the City of Zagreb (Capitol of Croatia), but according to current practice there is need for improvement of mitigation measures applied in the phases of urban planning, construction and civil protection. In the frame of Croatian-Japanese project ‘Risk Identification and Land-Use Planning for Disaster Mitigation of Landslides and Floods in Croatia’ it is planned to develop methodologies for landslide mapping and guidelines for application of hazard maps for selected pilot areas (in the project period 2009- 2014). Croatian landslide data base is aimed at collecting and dissemination of landslide information to enable perception of existing landslide hazard and risk by wider society, public and governmental entities involved in development and implementation of landslide mitigation measures. General objective of the research is to introduce systematic collection of data about landslides in Croatia in the form of data base aimed at dissemination of information to landslide professionals and wider society, primarily to public and governmental entities. Specific objectives are: (1) development of a web based landslide database ; and (2) collection of data about past and present landslides in Croatia. The core data which database will collect and maintain are the following: catalog of Croatian landslides (with landslide location, description and schematic presentation) ; bibliographic database of published and unpublished landslide maps and reports accessible by title, author, year, or keywords ; photographic materials (photos and slides). Activities related to development of data base encompass the following: (1) development a data model and data dictionary (data base content, structure, and terminology for describing landslide), and (2) development and implementation the pilot system architecture based on user needs (end-user ‘search’ interface and an administrative web interface). This paper presents results of collection of landslide data from various sources: geotechnical reports, diploma thesis, landslide inventories and unpublished landslide maps. Conceptual model of the data base is made on the basis of historical landslide data for the following landslides in the City of Zagreb, Primorsko- Goranska County and Istra County: Črešnjevec landslide, Granice landslide, Kvaternikova landslide, Podvinje landslide, Vidovčica landslide, Vinogradska landslide, Sloge landslide, Grohovo landslide and Juradi landslide.
