Forecasting of sea water overflows over sandy spits at western coast of Kamchatka
The sea level rise at Okhotskoe Sea coast of Kamchatka which may cause overflows of sea water over sandy spits is influenced by few factors. The main of those are: tides, wave setup, wind and wave surges, sea level rise dew to atmospheric pressure fall, etc. The first two phenomena are responsible for 75% of extreme sea level rise cases which cause overflows in question. The method used by the Kamchatka Hydrometeorological Center for the forecasting possible overflow time (method by V.F. Komcha-tov) takes account of these two processes. Automated version of this method coupled with Russian Atmospheric-Wave Model is proposed and recommendations for the improvement of this method on the basis of empiric information collected by specialists of the Center are given.
