Sažetak
Two campaigns, comprising the measurements of temperature, salinity, currents and sea level, were performed in the Zadar and Pašman Channels during summer 1994. Basic dynamics, including tidal, wind-driven and residual circulation, is briefly considered here, but the paper concentrates on the surface seiche and internal Kelvin wave analyses and modelling. Surface seiches are found to be excited by a strong meteorological disturbance which occurred in late summer 1994, with a period of about 2.2 h and the sea-level and current amplitude of about 10 cm and 9 cm/s, respectively. Internal Kelvin waves appeared during July having a period of about 4 days and maximum surface currents of about 8 cm/s. The energy loss at the head of the basin, occurring due to the basin bathymetry, is analytically modelled by imposing the radiation condition there both for the surface seiches and internal Kelvin waves, while the nodal line is enforced at the basin mouth. The modelled periods of surface seiches and internal Kelvin waves are 2.1 h and 96 h, respectively. The currents and sea levels agree fairly well with the observed values. Furthermore, the Defant numerical procedure, which allows for a variable basin bathymetry, gives slightly lower periods (1.9 h for the surface seiches and 91 h for the internal Kelvin waves) and moves the maximum current amplitudes towards the head of the basin in agreement with the observations.
