15 Flood Risk Management System in Poland
287
area storm, floods are recorded. In the winter season, the risk of ice-jam floods is
increased. Data on floods in Poland confirms that the greatest number of floods have
been recorded on the upper Vistula and Oder, and their mountain tributaries (see
Fig. 15.4).
Studies of the long-term flood occurrence trend in Europe have shown an
increasing number of great floods (in the period 1985–2007), which overlap with
a high variability of the events (Dartmouth Flood Observatory). This means that the
character, intensity, and incidence of floods is dependent mainly on the climatic and
geographic circumstances, as well as human activity [49]. These factors determine
the level of susceptibility and exposure of an area to flood, which, besides a threat,
are also flood risk attributes.
