Subject aims expressed by acquired skills and competences
Learning outcome of the course is to extend students' competence in analytical and numerical modeling of hydraulic and transport processes in the geosphere. In addition to studying the theoretical principles of mathematical modeling of groundwater flow and solute and heat transport, the students will learn to use the available software tools in practice and apply them to issues in environmental and energy geotechnics.

Summary
The course is focused on the theoretical and practical aspects of analytical and numerical modeling of hydraulic and transport processes in the geosphere. Students will be acquainted with the theoretical principles of mathematical modeling of groundwater flow and transport of solutes and heat in the rock environment, including implementation of governing equations, initial and boundary conditions by various numerical methods (finite difference method, FEM). Part of the study is also the application of the selected software tool available at the Department of Geotechnics and Underground Engineering (FEFLOW, MODFLOW, MODPAT, MT3D, PEST, etc.) on the selected case study in relation to the solved problems within the doctoral study.
