Lowering rates of limestone along the Estern Istrian shoreline and the Gulf of Trieste

This paper discusses the data on the lowering of carbonate surfaces thar have been taken from a series of measurements sires located along the shoreline of the Gulf of Trieste and of Westrern Istria, paying particular attention to the phenomena occurring in the intertidal zone. These lowering rares have also been compared with those of limestone outrcropping in the Classical Karst area. The mean lowering rare of limestones along the North Eastern Upper Adriatic Sea is approximately 0.13 mm/yr, with significant changes depending on the sire: in Trieste,the mean annual rare is 0.40 mm/yr: in the sires located along the Istrian shoreline, the mean annual rare is 0.09 mm/yr
