In this paper we introduce a landslide prediction system for modelling the probabilities of landslides through time in Slovenia (Masprem). The system to forecast rainfall induced landslides is based ...on the landslide susceptibility map, landslide triggering rainfall threshold values and the precipitation forecasting model. Through the integrated parameters a detailed framework of the system, from conceptual to operational phases, is shown. Using fuzzy logic the landslide prediction is calculated. Potential landslide areas are forecasted on a national scale (1: 250,000) and on a local scale (1: 25,000) for fie selected municipalities where the exposure of inhabitants, buildings and different type of infrastructure is displayed, twice daily. Due to different rainfall patterns that govern landslide occurrences, the system for landslide prediction considers two different rainfall scenarios (M1 and M2). The landslides predicted by the two models are compared with a landslide inventory to validate the outputs. In this study we highlight the rainfall event that lasted from the 9th to the 14th of September 2014 when abundant precipitation triggered over 800 slope failures around Slovenia and caused large material damage. Results show that antecedent rainfall plays an important role, according to the comparisons of the model (M1) where antecedent rainfall is not considered. Although in general the landslides areas are over-predicted and largely do not correspond to the landslide inventory, the overall performance indicates that the system is able to capture the crucial factors in determining the landslide location. Additional calibration of input parameters and the landslide inventory as well as improved spatially distributed rainfall forecast data can further enhance the model's prediction.
In the frame of national research and innovation project MASPREM exposure maps of inhabitants, buildings and infrastructures to landslide occurrence were developed for five selected Slovenian ...municipalities. Maps represent an upgrade of the landslide susceptibility maps that were elaborated based on synthesis of analysis of event-based landslide inventory and field investigations. Exposure maps were developed for five municipalities: Bovec, La{ko, Slovenj Gradec, Trbovlje and Železniki. Exposure of inhabitants, construction and infrastructures to landslide occurrence was analysed using simple cross-analysis of landslide susceptibility maps at scale of 1:25,000 with locations of exposed elements. All analyses were conducted in the GIS with software tool ArcMap. Exposure maps, based on landslide susceptibility, were classified into six classes, with values ranging from one to six where class one represents areas with negligible exposure and class six areas with very high exposure to landslide occurrence. Exposure maps of selected municipalities provide the basis for further assessment of risk and consequentially better risk management.
Primary and secondary mineral resources are of strategic importance for the EU. Most EU countries (including Slovenia) are already part of the pan-European Minerals Intelligence Network which ...provides consistent and organized data information on primary and secondary mineral resources on the European level. It was established in previous projects as EuroGeoSource, Minerals4EU, ProSUM, Mica and ORAMA. The Eastern and south Eastern European (ESEE) region represents a gap in this network, but at the same time is also identified as one of most important strategic regions for the EU with great potential for mineral supply. The large concerns are aiming to expand their business to the region, but access to relevant data interesting for the investors is still not available. There is a need for surveyed and unified mineral resources data. In the framework of RESEERVE (EIT RM KAVA project, duration 1.4.2018-31.3.2021), national mineral resources data of six task partners from West Balkan countries (Albania, Bosnia and Herzegovina, Croatia, Serbia, Montenegro and Macedonia) were implemented and harmonized with INSPIRE directive (European directive for organizing spatial data). Since EU directives are mandatory for members only and West Balkan countries are not yet targeted (except Croatia), they are still interested in their implementation. For that reason the main project goal is the creation of the West Balkan Mineral Register, provided by national data providers, which will represent a starting point to integrate the ESEE region into existing EU data platforms and bring it closer to common minerals market. Regional mineral data will become more accessible and relevant. The goal of the project is to anticipate the future supply and demand for minerals, particularly regarding critical minerals and therefore to contribute to the sustainable mineral supply in Europe. Leading partner for RESEERVE project is Geological Survey of Slovenia (GeoZS), which has identified relevant data providers and examined data quantity, quality, and format. GeoZS will synthesize primary and secondary raw material data into common West Balkan Mineral Register and test the harvesting of data in INSPIRE compliant European data model. The scenarios drawn up in the project will be available through the European Geological Data Infrastructure (EGDI), which will offer easy access to existing mineral data. EGDI provides access to Pan-European and national geological datasets and services from the Geological Survey Organizations of Europe. Through EGDI data from several European data harmonization projects are accessible. EGDI was launched in June 2016 in a Version 1 and has since then been extended to include more data sets, including mineral resources. The article is mostly focused on workflow harmonizing the data and spreading IT knowledge of mapping the national primary and secondary minerals data to already existing European data model and developing national relational databases, that fit into European common database structure. Data harmonization was already performed through national training workshops to assist task partners in taking the first step toward INSPIRE directive implementation.

Gathering and analysing of the geological data of a certain area is a procedure where various spatial data are related and processed. The aim of a geologist is to determine the model that will ...represent the natural conditions by its most and will help him solve relations between data. Usually geological data have various origins and are for the purpose of modelling merged, united or joined together. The result is a geologic map that forms a foundation for the comprehension of the real geological conditions of a given area.The paper presents conceptual and logical model of the geological maps in the GIS environment. Here characteristics of the database, the standard procedures for the data input and their quality control procedures are shown.

The purpose of the paper is to present the field data relational database, which was compiled from data, gathered during thirty years of fieldwork on the Basic Geologic Map of Slovenia in ...scale1:100.000. The database was created using MS Access software. The MS Access environment ensures its stability and effective operation despite changing, searching, and updating the data. It also enables faster and easier user-friendly access to the field data. Last but not least, in the long-term, with the data transferred into the GISenvironment, it will provide the basis for the sound geologic information system that will satisfy a broad spectrum of geologists’ needs.

Safeguarding Drinking WaterLjubljana's water resources lie in the immediate vicinity of built-up urban areas or even below them. For decades, they have been safeguarded as water-protection areas, ...which are specified by implementing regulations. However, formal protection through regulations is insufficient if the goal is to manage these sources in a sustainable manner. One of the most important goals of sustainable management is maintaining suitable provision of fresh drinking water without using any technological procedures to
