2.  Austria is located within 3 international river basin districts – Danube, Rhine and Elba

4.  The occurrence of floods is seasonally dependent

5.  There is a change in flood frequency due to human intervention  Due to land use, impoundments, dikes and reservoirs the flood frequency has been changed  Climate change may have severe impacts in urbanised areas and in mountainous regions

6. Runtime of flood peaks from Ybbs to Vienna - 1954. -> 54h - 1965. -> 45h - 1975. -> 38h - 1981. -> 32h - 1991. -> 16h

8.  From linear measures to dikes, levees, reduce the discharge capacity  From spatial measures to flood storage reservoirs

9.  From non-structural measures to flood warning systems, real time operation of reservoirs, preservation and increase of retention capacity

10.  Around 2.2 billion dollars  New dikes, river training – 3151.8km  Maintainance works of dikes -11 598.3 km  Newly flood protected area - 71 547.8 ha  Drained areas - 23 875.0 ha

11.  The flood protection for residential areas should be improved  The retention capacity in the basin should be enlarged  The ecological state of the riverine system should be preserved or improved  The public should be integrated in the decision making approach

12.  The river basin approach – basis – risk zonation map with long term objectives (risk of 100 year wave)

13.  No flood protection for agricultural land – instead signing policies with the insurance companies – the higher the risk, the more expensive the policy gets
