Engineering Geological Map of Bosnia and Herzegovina
The Engineering Geological Map of the Federation of Bosnia and Herzegovina is characterized by a pronounced variety in lithostratigraphic composition (rocks and rock complexes are often tectonically heavily damaged), a high degree of seismic activity, complex hydrogeological properties, pronounced relief, varying climate, and steeply inclined watercourses, as well as significant anthropogenic impacts on the terrain. These specific characteristics largely determine the engineering-geological properties of the terrain. Based on these characteristics of the Federation of Bosnia and Herzegovina, the map displays the following: Lithological composition with important physical properties of rocks and rock complexes formed by endogenic and exogenic geological processes. Engineering-geological features that classify areas based on stability and the degree of seismic activity. In addition to the lithological composition, endogenous phenomena such as faults (fractures, shells, and covers) are shown. Modern exogenic geological processes are illustrated by phenomena directly resulting from these processes on the terrain, such as areas prone to landslides, rockfalls, rapid erosion, gully formation, and debris flow. The stability of slopes is categorized into three classes: stable, conditionally stable, and unstable terrains. Considering the significant impact of earthquakes on engineering-geological conditions, the map delineates areas with different levels of seismic activity according to the MCS scale.
The Engineering Geological Map of Bosnia and Herzegovina at a scale of 1:500,000 was developed based on the Engineering Geological Map of SFR Yugoslavia, which was primarily created using unpublished documents as well as data from literature. The map was produced by the Department of Engineering Geology and Hydrogeology at the Institute for Geological and Geophysical Research in Belgrade between 1962 and 1965. In the first version of the map, the terrain was categorized based on lithological composition. The map was prepared following guidelines developed at the Institute for Geological and Geophysical Research. During this phase, the Institute collaborated with: The Geological Institute in Ljubljana - F. Drobne, T. Nosan, and Lj. Žlebnik The Institute for Geological Research in Zagreb - V. Šikić The Department of Engineering Geology and Hydrogeology at the Civil Engineering Faculty in Sarajevo - R. Jovanović and Z. Bračinac These institutes conducted research in their respective republics. Seismicity studies were based on a tectonic map with a special emphasis on neotectonic elements. The work during this period was carried out by the Institute for Geological and Geophysical Research - P. Čubrilović, Lj. Palavestrić, T. Nikolić, and N. Radović. The tectonic map with neotectonic elements was prepared by B. Ćirić. Seismic maps showing epicenters and isoseismal lines of maximum intensity were created by V. Ribatić from the Astronomical-Geophysical Observatory of the University of Ljubljana, D. Cvijanović from the Geophysical Institute of the Faculty of Natural Sciences and Mathematics in Zagreb, and M. Janković from the Seismological Station in Sarajevo. The map interpretation was completed later in 1966. It was created in vector format by the Federal Institute for Geology in accordance with modern Geographic Information System (GIS) software programs, and the complete content of this map is an integral part of the engineering geological database (gdb).
