Metadata Details: Engineering-geological map of Bosnia and Herzegovina

The engineering geological map of FBiH is characterized by a distinct diversity of lithostratigraphic composition (rocks and rock complexes are often tectonically very damaged), a high degree of seismic activity, complex hydrogeological properties, distinct relief, different climates and water flows with a large slope of the bottom, and a significant impact of anthropogenic influences on the terrain. These specificities, to a greater or lesser extent, already predetermine the engineering-geological characteristics of the terrain. Based on the mentioned specificities of the FBiH area, the map shows: lithological composition with important physical properties of rocks and rock complexes that were created by endogenous and exogenous geological processes. On the basis of engineering geological features, the terrains are rezoned according to the degree of stability and the degree of greatest seismic activity. In addition to the lithological composition of the terrain, engoden phenomena such as fractures (faults, shells and covers) are also shown. Contemporary exogenous geological processes are shown by phenomena that are a direct consequence of those processes on the ground. These are areas that are threatened by rock slides and landslides, rapid washing, the creation of ravines and debris from torrents. According to the stability of the slopes, the terrains are classified into three categories (stable, conditionally stable and unstable terrains). Acknowledging the exceptional impact of earthquakes on the engineering-geological conditions of the terrain, the map delineates areas of different degrees of the strongest earthquake activity according to the MCS scale.

The engineering geological map of Bosnia and Herzegovina M 1:500,000 was created based on the engineering geological map of the SFR Yugoslavia, which was created mostly on the basis of unpublished documents, but also on the basis of data from the literature. The map was created in the Department of Engineering Geology and Hydrogeology of the Institute for Geological and Geophysical Research in Belgrade between 1962 and 1965. In the first version of the map, the terrain was divided according to lithological composition. The map was created according to the instructions developed by the Institute for Geological and Geophysical Research. In this phase of work, the following collaborated with the Institute: Geological Institute in Ljubljana - F. Drobne, T. Nosan and Lj. Žlebnik; Institute for Geological Research in Zagreb - V. Šikić; Institute for Engineering Geology and Hydrogeology of the Faculty of Civil Engineering in Sarajevo - R. Jovanović and Z. Bračinac. The institutes conducted this research in the areas of the republics to which they belong. The study of the seismicity of the terrain was carried out on the basis of a tectonic map with particularly prominent elements of neotectonics. The work in this period was carried out by the Institute for Geological and Geophysical Research by P. Čubrilović, Lj. Palavestrić, T. Nikolić and N. Radović. The tectonic map with elements of neotectonics was prepared by B. Ćirić. Seismic maps with marked epicenters and isolons of the highest intensity were prepared by V. Ribatić from the Astronomical and Geophysical Observatory of the University of Ljubljana, D. Cvijanović from the Geophysical Institute of the Faculty of Science and Mathematics in Zagreb and M. Janković from the Seismological Station in Sarajevo. The map was interpreted subsequently in 1696. It was created in vector form by the Federal Institute of Geology in accordance with modern software programs for Geographic Information Systems (GIS), and the complete content of this map is an integral part of the engineering geological database (gdb).
