The main objective of this article is the evaluation of the contemporary land cover of areas exposed to floods. Two small towns in which flooding risk is high - Poddębice and Uniejów in lodzkie voivodeship, were chosen for detailed analysis. The area exposed to floods means an area that is probable to be covered by water once for a hundred years. The evaluation of the contemporary land cover was based on Topographic Database as well as local stocktaking, and supported by the use of GIS tools. The exposed areas aren't protected enough on the local level as far as planning instruments, especially local spatial development plans, are taken into consideration. As a result, the directives formulated by the heads of Regional Water Management Boards aren't used in practice, because they restrict land development of the attractive areas and hamper local economic development, even despite the fact that those areas are endangered by floods.

The flooded areas are one of the most conflicting areas. Spatial policy and planning on such areas of special flood hazards and their disastrous consequences should be carried on carefully, in accordance with the principles of sustainable development. Changes in Polish law, especially in water law (resulting from EU directives) require changes in the spatial policy on such areas. These changes can have long-lasting negative consequences especially in small towns, if they are not carefully thought out. In article were described negative consequences of floods and prevention, law regulations in the spatial policy on floodplains and the potential negative consequences of bad policy, especially in small cities.

Samorządy terytorialne w gminach województwa śląskiego systematycznie zmagają się ze skutkami powodzi, które wywołują wysokie straty społeczno-ekonomiczne. Kompensacja szkód katastroficznych prowadzona przez gminy oparta jest na udzielaniu pomocy socjalnej poszkodowanym oraz wypłacie rekompensat za szkody powodziowe. Przedsięwzięcia profilaktyczne koncentrują się na czynnościach prawno-administracyjnych, a także konkretnych działaniach poprawiających bezpieczeństwo powodziowe w terenie. Przeprowadzone badania wskazują, iż zasadne wydaje się wzmocnienie działań profilaktycznych w stosunku do działań kompensujących szkody katastroficzne.

The local governments in the municipalities of Silesian Voivodeship systematic struggle with results of flood, what causes high social and economic losses. The compensation of the catastrophic losses, conducted by municipalities, is based on providing social assistance to victims and on paying compensations for flood losses. Preventive actions are focused on legal and administrative functions, and on specified actions improving flood protection in the area. The studies indicate that strengthen preventive measures in relation to compensatory measures appears to be justified.

W badaniu wyselekcjonowane zostaną maksymalne stany wód dla wybranych horyzontów czasowych. W ten sposób otrzymane zostaną realizacje określonych zmiennych losowych, które aproksymowane będą odpowiednimi rozkładami Poissona. Z dopasowanych teoretycznych rozkładów Poissona policzone zostaną prawdopodobieństwa przekroczenia progów ostrzegawczego i alarmowego, które traktowane będą jako miary ryzyka zagrożenia powodziowego

The main purpose of this article is the using the Poisson distribution to estimate the risk of flood danger on the Odra river in Oława. Lower Silesia belongs to one of the most dangerous regions in Poland of waterboarding and floods. In research the maximas of water level will be selected for chosen times horisont. In this way, given determined random variables, will be approximated by relevant Poisson distribution. In fitted theoretical Poisson distribution it will be counted the probability od transgression warning and alarm level which will be treated as a risk measure of flood danger.
