Abstrakt

According to the definition of flood, presented in Water Law, it is a sudden inundation by water of an area which is normally arid. Dolnośląskie Voivodship, which in this article is the object of analysis concerning flood safety, experienced in its history a flood disaster in July 1997. Flooding in this area is caused mainly by heavy and prolonged rainfall occurring from June to August. Actions aimed at flood mitigation are: increasing forest cover of the basin of the river, restoring natural flood plains of rivers (where possible), appropriate agrotechnology, maintenance of river channels, reducing building in flood plains, accurate weather forecasting. In the Odra basin, where there are many urban centers, it is necessary to use technical tools such as levees, multi-purpose water reservoirs, dry flood reservoirs, polders, pumping stations, and relief canals, to prevent flooding.
