This paper presents application of flood scenarios, which are in possession of Coordination and Information Center for Flood Protection (OKI), a department of Regional Water Management Authority in Kraków. Flood scenarios describe situation during the flood on a specified area with definite flood hazard degrees. Flood scenarios contain information about water and levee elevation in specific crosssections and along longitudinal profiles of river beds, about discharge values in case of an overflow over levee and extent of the flood wave with determined exceedence probability or extent of historical floods. Flood scenarios are divided into static and dynamic ones. Static scenarios do not present flood distribution in time, but only the maximum extent of a flood wave with determined exceedence probability. On the other hand, dynamic scenarios present flood expansion in time taking into consideration, for instance,, levee breakage or washing out, polder opening, or influence of a retention reservoir. Additionally, both static and dynamic scenarios are divided into historical scenarios (with records of flood progression in the past) and hypothetical scenarios (models of floods with values calculated on the basis of the phenomenon that is probable to happen in the future, taking into consideration specific features of a basin ). In view of data availability, at present it is only possible to formulate static scenarios. The range of individual scenarios is connected with the range of flood wave transformation model, which is in possession of OKI. Nowadays OKI has flood scenarios for the following river sections: m Wisła from Goczałkowice reservoir to Gromiec water-gauge, m Wisła from Gromiec water-gauge to Smolice water-gauge, m Wisła from Smolice water-gauge to Popędzynka water-gauge, m Wisła from Popędzynka water-gauge to Karsy water-gauge, m Wisła from Karsy water-gauge to Szczucin water-gauge, m Wisła from Szczucin water-gauge to Sandomierz water-gauge, m Wisła from Sandomierz water-gauge to Zawichost water-gauge, m Soła below Czaniec reservoir to estuary, m Skawa below .winna Poręba reservoir to estuary, m Raba below Dobczyce reservoir to estuary, m Uszwica from Okocim resort to estuary, m Dunajec below Sromowce Wyżne reserwoir to the Rożnów reservoir backwater, m Dunajec below Czchów reservoir to estuary, m Nida below Czarna and Biała Nida joint to estuary, m Wisłoka from Jasło town to estuary, m San from Dynów water-gauge to estuary, m Wisłok from Łęki Strzyżowskie resort to estuary. Currently, OKI administers flood scenarios for the 1%, 2%, 10% and 20% exceedence probabilities for all river-sections specified above. Because of lack of Digital Model Terrain (DTM) for the whole area, flood hazard zones were formulated only for Wisła, Raba and Nida sections and enclosed to the flood scenarios. Flood hazard zones for others sections will be formulated and systematically enclosed in the future as databases in OKI within DTM are fulfilled. Works connected with new scenarios for other values of probability are proceeding all the time. The aim of this presentation is to show the results of these works and to get familiar with the role of the scenarios in thedecision supporting process in case of flood.

Przedstawiono wybrane rodzaje analiz z zakresu ochrony przed powodzią realizowane w Ośrodku Koordynacyjno-lnformacyj-nym RZGW w Krakowie w czasie powodzi i w okresach między powodziami. Pokazano jak praktycznie i do czego wykorzystywane są m.in. produkty i narzędzia, jakie powstały w ramach projektu Banku Światowego, a także w efekcie opracowywanych na zlecenie RZGW studiów określających granice obszarów bezpośredniego zagrożenia powodzią dla terenów nieobwałowanych.

There are presented in the paper selected types of analyses concerning the flood control carried on by the RZGW Coordination and Information Centre during the floods and in the periods between the floods. There has been shown examples of how practically and for what purposes are used the products and instruments originated in the framework of the project of the World Bank as well as created in result of study works undertaken on initiative by RZGW determining on terrains not protected by embankments the limits of the areas directly endangered by flood.

Opisano podstawowe produkty i narzędzia, jakie zostały pozyskane do wspomagania działań z zakresu ochrony przed powodzią realizowanych w Ośrodku Koordy-nacyjno-lnformacyjnym RZGW w Krakowie w ostatnich kilku latach. Są to m.in. produkty i narzędzia, jakie powstary w ramach projektu Banku Światowego „Usuwanie skutków powodzi", ale również w wyniku własnej inicjatywy RZGW Kraków.

There are described products and intruments used as aids in flood control activities carried out by the Coordination-Information Centre of the RZGW in Cracow in the last few years. These are a.o. products and instruments which originated in the framework of the World Bank's project „Liquidation of effects of floods", but also in result of the initiative taken by the RZGW itself.
