Description :
The coastal scenery of the Northeastern Adriatic sea is widely interested by caves and related coastal features, which are developed in correspondence of geological weaknesses of sea cliffs. We present the preliminary surveying of five partially submerged coastal caves cut in limestone cliffs, relating the dissolutionally widened vadose karst voids and the present-day forms. The analysis pointed out two well-defined morphological zones inside the caves. The boundary between the zones roughly coincides with the mean sea level. The submerged zone is mainly affected by abrasion processes on the bottom and the lateral walls, while the emerged zone is interested by karst processes and collapse of blocks from the roof. Their effects produce a bell-shaped cross-section, in which the submerged part of the caves is significantly larger than the emerged one. - (NF)
