Problémy a modely v předpovídání záplav
 Hokr, Milan ; Maryška, Jiří ; Šotner, O.
In the paper, we deal with the flood forecasting, in particular with determining the water flow as result of known precipitation. In the first part, we present several approaches how to express the water flow in the environment concluding underground flow, surface flow and channel flow in the ricer system (water runoff and flood routing). We discuss possibilities to simplify the shallow-water equations for slowly varying flow to either potential flow or advection-dispersion process. On the second part, we present results of two example models of 2D surface flow in the landscape, first based on the advection-dispersion representation of surface flow and the second mixed-hybrid FEM model based on potential flow approximation.

Discrete Minimax Approximations with Application to Filter Design
 Lukšan, Ladislav ; Vlček, Jan
The contribution contains a description of two different methods for discrete minimax approximation. These methods can be applied to electrical filter design. We demonstrate properties of these methods on the optimal design of a fourth order band-pass filter. Numerical results of our computational experiments and corresponding conclusions are presented.
