The series "Engineering Geology and Hydrogeology"- tradition and priorities
Prof. Victor Spasov
The Engineering Geology and Hydrogeology series was founded in the middle of the last century, in a period of intensive development of the science in Bulgaria and its application in large-scale hydrotechnical, hydro-meliorative and infrastructure projects. The journal, created within the framework of the Bulgarian Academy of Sciences, makes high demands on publications in terms of their scientific and applied essence, the relevance of the issues under consideration and their proper layout.
The series comes out sequentially as:
- Works on the geology of Bulgaria – Series Engineering Geology and Hydrogeology (1962-1966);
- Bulletin of the Geological Institute at the Bulgarian Academy of Sciences – Series Engineering Geology and Hydrogeology (1967-1974).
From 1974 until now, a separate edition of "Engineering Geology and Hydrogeology" has been published. After a break (1998-2009) due to budgetary reasons, the publication of the journal was resumed with issue 25 in 2010. Since then, it has been published regularly with one issue per year. Traditionally in the series there are published works devoted to engineering geological conditions within the range of different types of engineering facilities (constructions, dams, tunnels, roads and bridges, gas pipelines, ports, radioactive waste repositories, geological conditions for urban planning and settlement development and others). Recently there has been a decrease in the volume of field research and testing of construction sites worldwide.
For the characterization of construction sites, with limited number of field data, more and more specialized software products are used for 2D or 3D modeling. The experience and results of applying modern methodologies always have a place on the pages of the journal. In addition to securing the construction projects with the necessary geological justification, another task is the assessment of the geological risk associated with unavoidable natural phenomena such as earthquakes, landslides, floods, etc.
The majority of the municipalities in Bulgaria are supplied with water from groundwater sources. However, the quantities of water extracted are insufficient and hundreds of settlements remain in the water regime, especially in the summer. The Bulgarian Hydrogeological Community is called upon to contribute to the optimal and sustainable use, protection and management of groundwater. Published results of regional hydrogeological studies, as well as the applied methodological approaches, help to clarify the groundwater potential in a quantitative and qualitative aspects. Current studies on groundwater pollution caused by agricultural activity, industry and various types of waste are also relevant in this respect. In hydrogeological practice it has become routine to produce computer models (mostly based on MODFLOW) for different areas. However, often they are not sufficiently secured by proper established hydrogeological parameters and boundary conditions. Higher demands on the conceptual modeling of the models and verification of the resulting solutions are required.
Over the past two decades, the global geological community has focused its attention on global challenges. Hydrogeology and Engineering Geology emerged as priorities in the geological sciences. The International Union of Geological Sciences in its Medium-Term Vision and the Strategic Action Plan (IUGS MidTerm Vision and Strategic Action Plan 2003) poses the following primary issues:
- Geoscience and circle of water
- Geological hazards and risk mitigation
- Earth resources and sustainability
- Global changes and evolution of Life
- Earth in depth: how it acts on our environment
Engineer-geologists and hydrogeologists are called to be among the specialists who provide vital decision-making information to reduce and mitigate human impacts on the geosphere and the hydrosphere.
The Editorial Board, restoring the publication of the Engineering Geology and Hydrogeology series in 2010, has the good will to promote researches in those fields and to contribute to the dissemination of knowledge and results among the scientific and professional community.
