Sažetak
Wind and current data measured off the northwestern Adriatic coast in November and December 1978 have been analysed. The data have shown that bura - the characte­ristic winter wind in this area - induces downwind currents over the whole water column. A typical bura impulse of 10-12 m/s induces currents of about 50 cm/sat the surface and 30 cm/sat the bottom. The results of the numerical model of the Northern Adriatic have shown that it is possible to approximate the empirical results if the wind curl, besides the bottom slope, is taken into account. The numerical model has also shown that the alongshore dynamics in the station area can be reasonably well approximated by the balance of surface and bottom stresses. The empirical results and the mentioned balance suggest that, for this part of the Adriatic, the quadratic law for bottom friction is not superior to the linear one. Calculated values of the coefficient of linearized bottom friction (1.13-1.24 x 10-3 m/s) are in good agreement with values determined previously for the area by other methods.
