Tutor:

Martina Sobotková, Martin Šanda

Supervisor:

Department of Landscape Water Conservation

Synopsis:

The course deals with the problem of groundwater flow in saturated rock environments. The introduction of the course is devoted to the theoretical background and mathematical description of groundwater flow. The next part is devoted to simplified solutions of basic problems - flow through phreatic and confined aquifers, seepage through an earth block, flow in the vicinity of wells. At the end of the semester, students will get acquainted with the method of numerical modelling of groundwater flow, using specialized software to solve an individual problem.

Requirements:

Participation in exercises, processing of assigned problems

Syllabus of lectures:

1.Introduction to groundwater hydraulics, basic world overview, application of tasks

2.Importance of groundwater, types of subsurface water, classification of aquifers
