Guidebook for the preparation of the Basic Engineering Geological Map of the Republic of Srpska 1:100 000

The Guidbook for the preparation of the Basic Engineering Geological Map (BEGM) of the Republic of Srpska is adopted by the Minister of Industry, Energy and Mining under the Law on the Geological Researches (Official Gazette of the Republic of Srpska, No 51/04 and 75/10). The responsible institution for preparation of the Guidebook was the Republic Survey for Geological Researches.
The Guidebook for the preparation of the Basic Engineering Geological Map of the Republic of Srpska (in further text – the Guidebook) represents a subordinate legislation, a mandatory booklet for regional and detailed study of engineering geological features of the terrain. For engineering geological maps of different scales this legislation stipulates requirements regarding the research methodology, the volume and types of data which should be collected and the way of presenting the results. The content of the Guidebook is adapted to the modern world trends and enables the preparation of digitalized engineering geological map and data processing in the GIS. The Guidebook is prepared in accordance with the Law on the Geological Researches, the Rule on the content of programs, projects and elaborates of the geological researches, the recommendations of the International Association for Engineering Geology and Environment and international standards and recommendation for preparing of the engineering geological maps.
In the preparation of the Guidebook the positive experiences of the previous Guidebook from 1988 were used, as well as new findings in solving different engineering geological problems. Draft Guidebook was prepared primarily for the preparation of the Basic Engineering Geological Map, but it could be used even for the preparation of the engineering geological maps in small, medium and large scale.
Depending on the scale for each type of the engineering geological maps there are determined the requirements regarding the content of necessary engineering geological features in the description of individual determined lithological types and complexes.
The BEGM is a type of map which contains the general presentation of all those elements of the geological environment important for spatial planning, designing, construction and exploitation of the object in civil engineering, mining, environmental protection and other related fields.
It contains the following features:
1. Characteristic of rocks and soil: including their division, stratigraphic and structural classification, origin, lithological and tectonic characteristics, physical condition and mechanical features;
2. Hydrogeologic conditions – division of the rocks and soil by hydrogeological functions; with the data about the zones of saturated soil, the levels of groundwater, a range of level fluctuation and the directions of groundwater flow; springs, rivers, lakes, the borders of periodicaly flooded areas, pH, chemical content of groundwater, corrosivity;
3. Geomorphologic conditions – genetic types of relief and important elements of natural environment (landscape); geomorphologic forms by the time of origin, structure, direction, shape and height;
4. Geodynamic phenomena – egzodynamic processes and occurrences – erosion, denudation, karst areas, gravitational movements on the hillside (landslides, rockfalls, debris flows, mudflows); endodynamic processes and occurrences – seismic phenomena, active faults, the zones of current tectonic movements (neotectonic activities).

The BEGM is prepared for the terrains for which there already exists the Basic Geological Map of Bosnia and Herzegovina (BGM) and the Basic Hydrogeological Map (further: BHGM) or executed regional hydrogeological researches.
It could be prepared together with the BHGM or in exceptional cases independently of it, when the hydrogeological data have been collected during the engineering geological mapping or they are used from the existing expert papers on the executed regional hydrogeological explorations.

The final BEGM is prepared in a digital form. All collected data and research results will be entered into the subsequently formed engineering geological cadastre and the database.

Half-qualitative and quantitative data enter into the engineering geological (EG) database in a textual, numeric and graphic form.
