Neustaly rozvoj navrhovych metod ve stokovani, ktere posuzuji srazko-odtokovy proces na urbanizovanych povodich, vynucuje zmeny v pristupech stanoveni navrhovych dest'u. Velkou zmenou v metodice byl predevsim vseobecny odkIon od empirickych navrhovych rovnic mestske hydrologie k dynamickym simulacnim modelum [3]. Ty daleko presneji stanovuji hydrologicke a hydraulicke jevy ve stokovych sitich. Technicky pokrok v oblasti modelovani vsak prinasi problemy souvisejici s potfebou velkeho mnozstvi potfebnych vstupnich dat,mimo jine take v oblasti dest'ovych vstupu. V soucasne dobe Dent v CR normalizovan zavazny postup pro stanoveni parametni navrhovych dest'ovych vstupu pro dynamickou simulaci ve stokovani. V zahranici doporucovany postup kontinualni simulace pomoci historicke cady dest'u je velice pracny a nakladny. Predkladana price nabizi jednoduchou metodiku vyberu nekolika historickych udalosti z dlouhodobych dest'omemych zaznamu, ktere mohou reprezentovat navrhovou udalost s periodicitou vyskytu odpovidajici vyznamu odvodnovane oblasti.

The most important parameter influencing the flow in the sewerage networks in the urban hydrology are especially the rainfall courses. The choice of the rainfall for the design decides on millions of investment means destined for building or running the drainage device. Specifically still more popular dynamic simulation based on mathematical models does not have, in Czech Republic, standardized algorithm for setting the parameters of the design rainfall input data. The paper describes method how to select several real rains from the long-tenn rainfall series, which can be used for the design of a drainage system.
