Sažetak
On 21 June 1978, a tsunami-like event occurred in the Adriatic Sea. It resulted in the trough-to-crest height reaching 6 m in Vela Luka on the Korčula Island and exceeding 1 m in many locations along both the Croatian and Italian coasts. The event broke the previous Adriatic records and was therefore the subject of a number of scientific and professional papers published over the past four decades. In the lecture, a subjective view of the research activities stimulated by the event is presented. Immediately after the event, a relative value of four possible interpretations was assessed, the distinction was made between two different types of resonance influencing it, and the term Proudman resonance was introduced in order to describe one of the types. However, an attempt aimed at reproducing the event with a numerical model failed at the time. It was only after three decades, during which the power of computers and numerical methods advanced at an unprecedented pace, that numerical modeling of the event could be tackled again. This resulted in an order-of- magnitude reproduction of the event with an oceanographic model, an experimental coupling of the oceanographic model to a meteorological model, and an attribution of the event to a four-phase process capable of transforming a few-hectopascal air pressure perturbation into a few-meter sea level oscillation. The first numerical modeling of the event did not allow for the flooding of Vela Luka and drying of the harbor, which were amply documented by marks on buildings, numerous photos and even some films. Only recently, the flooding and drying option has been included in a numerical simulation and this brought the simulated heights close to the observed values. Therefore, the 1978 Adriatic flood still provides challenges to researchers and may be expected to do so in the future.
