Modular Wavemaker Design for Harbours and Ships Physical Model Testing

The paper presents design and implementation of a portable modular wavemaker system for producing regular and irregular waves in laboratory basins and fl umes. The system was built for the purpose of testing the impact of the sea waves on ships and coastal facilities. It is suitable for generation of all tipes regular and irregular surface waves. Modular system structure maintains high degree of fl exibility and reusability. Finally, the testing process on the physical model of Split harbour is described, and the currently obtained results are shown

Comparison of modelled and measured surface wind waves

Prikazana je usporedba rezultata mjerenja i numeričkog modeliranja površinskih vjetrenih valova na Jadranu. Model za valno generiranje uzima podatke o vjetru iz prognoze Aladin. Rabljene su dvije modelske prostorne domene: regionalna (Jadran) i lokalna (kanalski sustav jugoistočnog Jadrana). U lokalnoj domeni upotrijebljena je detaljnija prostorna diskretizacija. Stupanj korelacije izmjerenih i modeliranih vrijednosti primarno ovisi o pouzdanosti ulaznih podataka o vjetru.The comparison between measurement data and numerical modelling results for surface wind waves on the Adriatic is presented. The wave generation model receives wind data from the Aladin forecast. Two spatial model domains are used: regional (Adriatic) and local (south-eastern Adriatic channel system). A detailed spatial discrétisation is used in the local domain. The degree of correlation between the measured and modelled values is primarily dependent on the reliability of input wind data
