Towards Determining the Length of the Wind Waves of the Adriatic Sea

Valovi, kao morfološki oblik morske površine karakterizirani su visinom, duljinom i periodom, odnosno brzinom. Visinu i period vala moguće je točno odrediti na valomjernim plutačama. Duljinu vala moguće je samo približno odrediti, prema tome i brzinu vala. Najdulji su plimni valovi, kraći su seizmički, još kraći su valovi mrtvog mora, a najkraći su vjetrovni valovi. Vjetrovni valovi su najznačajniji glede sigurnosti pomorskog prometa te će se stoga njihova obilježja razmatrati u ovom radu. U literaturi se susreću matematički izrazi za duljinu vala koji daleko nadilaze vrijednosti koje se susreću na Jadranu. Empirijski izraz = 16,78 H0,71 zadovoljava u pogledu visine vala H i pripadne duljine za Jadran.Waves, as a morphologic form of the sea surface, are characterised by their height, length and period, or speed. The height and period of the wave can be measured with a high degree of accuracy by means of oceanographic measuring buoys. The length of the wave can be approximately derived, as well as the speed. The longest are the tide waves, shorter are the seismically waves, even shorter are the waves of the swell, while the windy waves are the shortest ones. The windy waves are the most important from the safety point of view and their characteristics will be analyzed in this paper. The technical literature is full of mathematical equations for the length of waves which exceed extensively the parameters of the Adriatic Sea waves. The empiric formula = 16,78 H0,71 correctly determines the lenght of the Adriatis Sea wave H and its corresponding length
