Summary
In the field of Environmental and Energy Geotechnics, geotechnics is connected on an interdisciplinary basis with environmental science issues and the use of geothermal energy through ground heat exchangers including the use of foundation structures.
In the course the knowledge of geotechnics in connection with its application in the field of environmental protection is synthesized. In addition to the specification of the impacts of geotechnical structures on the natural environment, the methods of their prediction and limitation of human impacts on the environment (slope deformations, effects of tunneling, changes in hydrogeological conditions, landfilling, etc.) are analyzed.
Upon completion of this course the student will receive extensive information from the fields of natural science (transfer of pollution and heat in the rock environment) including basic tools used in the field of environmental engineering. Basic types of geohazard and environmental risks arising from construction activities will be defined. Students will be acquainted with methods of technical solution of surface and underground landfilling of liquid and solid wastes (including radioactive), evaluation of their impact on the environment and system of preventive and reparative measures. Part of the subject is also the environmental impact of mining activities, especially with regard to the abandonment of mines (flooding of mines, stability of shafts, subsidence basins, redevelopment of tailings and ponds, etc.). In the field of energy geotechnics, students will be familiarized with the problems of technical solution and design of systems for exploitation of low-potential geothermal energy through drillied heat exchangers and foundation and ground structures.

2. Geotechnical risk assessment, management and sustainability. Risks and their evaluation - types of risks, risk management. Baseline ("Baseline") study. Environmental Impact Assessment EIA, Risk Analysis, Feasibility Study.
3. Geohazards. Types of geohazards - endogenous and exogenous (eg earthquakes, slope instability - landslides, floods, droughts). Survey, critical assessment. Preventive and reparative measures.
4. Soil and groundwater contamination. Sources of contamination, types of contaminants. Mobility of contaminants, transport mechanisms.
5. Investigation of contaminated sites, soil and water sampling. Remediation - Selection of the remedial method (In-situ methods, Ex situ, Containment reactive barriers, etc.).
6.-7.Construction of waste dumps (including mining). Types of waste, characterization and properties. Design of engineering barriers - covers, liners, underground impermeable walls. Application of geosynthetics in geo-environmental engineering - geotextiles, geocomposites, geomembranes, geosynthetic clay liners. Structural elements - stability of geotechnical structures of landfills (modification of slopes). Environmental impacts of landfills and their elimination (degassing, closure - remediation).
8.-9. Environmental impacts of mining activities – abandonment of mines. Mining waste - tailings, tailings dams, leaching fields - construction and remediation.
