The Krzywaniec reservoir is a part of Dychów complex hydraulic engineering, and it was created as a damming up water of the Bóbr river in 42+700 km to wave elevation 73.30 NN. The river valley was divided by three span gate weir and tide gate to derivation channel to ESP Dychów. The Krzywaniec reservoir is currently silted up so that the probable water surface Q1% is going to reach reservoir site embankment which means it poses the flood risk on surrounding area. The authors present restoring the initial situation on Krzywaniec reservoir, and estimated the reduction of flood depending on method of declogging the reservoir using computer simulation performed in HEC-RAS.

Floods in urban areas cause considerable economic losses and affect many people. Measures for flood mitigation in urban areas are primarily of an engineering character, however, existing city infrastructure very often restricts the introduction of appropriate new constructions. The city of Gdańsk is situated at the mouth of the Vistula river, on the area, which forms Vistula delta. It is the most flood-prone agglomeration in Poland. Now there are three possible flood sources. The first is from the moraine hills, in case of intensive precipitation. This area was recently rapidly urbanized. The second source of fl ood is from the Gulf of Gdańsk caused by storm surges and the third is from main channel of Vistula river in case of very high discharge or ice jam. The city of Gdańsk is situated within a complicated system of rivers and channels called Gdańsk Water Node (GWN). It is influenced by the discharge of rivers flowing from the moraine hills in the west, and from possible storm surges in the Gulf of Gdańsk. In July 2001 a severe flash flood, arising for the fi rst time from the moraine hills, caused by very intensive rainfall, hit Gdańsk. In the paper description of the operation of GWN, the flood cause, run and damages are presented. Description of measures, which were proposed to mitigate infl uence of a similar flood in the future are given. These measures were proposed on the basis of detailed field measurements, hydrologic analysis, hydraulic calculations and possible hydro-engineering developments.
