Abstract: [slo] [eng]
Príspevok sa zaoberá matematickou simuláciou povodne, ktorá postihla dolný tok Ondavy v roku 2010. Simulácia skúmala za pomoci 1-D modelovania hladinový režim v toku, pretečené množstvo vody cez bočný priepad a pomocou 2-D modelovania zatopenú plochu mimo hrádzového územia. Príspevok sa ďalej zaoberá alternatívnym znížením hrany priepadu a aj vybudovaním poldra, ktorého úlohou je zníženie zaplavenej plochy. Simuláciami bolo zistené, že aj napriek vplyvu bočného priepadu zabezpečia ochranné hrádze bezpečné odvedenie prietoku, len s periodicitou menšou ako 10 rokov. Contributions deals with a mathematical simulation of the flood that affected the lower Ondava in 2010. The simulation examined 1-D modelling of the level regime in the stream, the amount of water flowing through the lateral spillway, and 2-D modelling the flooded area outside the dike area. Contributions also deal with the alternative reduction of the spillway edge and the construction of a polder, the task of which is to reduce the flooded area. The simulations revealed that, despite the influence of the side overflow, the protective dikes would ensure safe drainage, only with a periodicity of fewer than 10 years.
