ÖVERSVÄMNING OCH KUSTEROSION PÅ GRUND AV KLIMATFÖRÄNDRING? / Flooding and Coast Erosion by a Changing Climate?
Today the west coast of Sweden can be flooded at a combination of strong winds from west and low pressures. In a future with climatic change and increasing precipitation and raising sea-levels a considerable increase of flood occasions can be expected. The consultant VBB VIAK has together with the municipalities of Göteborg, Kungsbacka and Halmstad tried to identify and describe the consequences of increasing precipitation and raising sea-levels. The study is based upon scenarios for the future, and for certain areas modelling calculations have been made. The result is that very large planned and built-up areas will be flooded already with water-levels of 0.25 m over the extreme high water of today. At a sea-level of 1.0 m over maximum high water-level unacceptable consequences will arise and very considerable proceedings must be carried out.
