Hydrometeorological causes of shore erosion along the polish coastline

Analysis of hydrometeorological data and of hypsometric measurements of the Hel Peninsula shore from the years 1989-1997 allowed determination of statistical relationships between averaged hydrometeorological parameters and morphological parameters of the shore. The significant relationship found between mean wind speed and sea level allowed an evaluation of their influence on the Peninsula 's shore. It is shown that long-term sealevel changes result in much stronger reaction of the shore than changes of wind speed. Quantitative relationships between the changes of hydrometeorological factors and the progress of erosion of dune coasts are presented on the example of the Hl Peninsula
