Synopsis:

The course provides an overview of computational methods for selected groundwater flow problems. The first part of the course is devoted to mathematical formulations of these problems. The second part is aimed at selected numerical methods, emphasizing implementation issues related to these methods.

Requirements:

Basic course of Calculus, Linear Algebra and Ordinary Differential Equations (in the extent of the courses 01MA1, 01MAA2-4, 01LA1, 01LAA2, 01NM held at the FNSPE CTU in Prague).

Syllabus of lectures:

1. Basic terminology and quantities, Darcy's law and its extensions.

2. Derivation of basic equations, classical formulation of the fluid flow problem in saturated zone.

3. Brief introduction to the theory of Sobolev spaces.

4. Weak formulation of the second-order elliptic boundary value problems.

5. Existence and uniqueness of the weak solution.

6. Finite Element Method (FEM) for steady-state flow equation in saturated domain.

7. Implementation problems related to FEM. Assembling of the equations, treatment of the boundary conditions.

8. Formulation of a non-stationary problem and its numerical solution by means of method of lines.

9. Discussion of alternative methods of time discretization, several special techniques.

10. Finite Volume Method (FVM) on dual mesh for parabolic equations.

11. Comparison of FEM with FVM, relation between these two methods.

12. Computer demonstrations of several simulation tools.
