Abstract

The paper provides analyses of the Krk Island coast vulnerability. The determination of the coastal
vulnerability index (CVI) was carried out for costal segments of 25 m in length and based on 5 selected parameters
(variables): geological composition, fabric coastal slope, significant wave heights, exposure to flooding, and the
existence and impact of shores. The presented results of the costal vulnerability analyses revealed the complexity of
the researched area, with significant variations of the vulnerability index along the island’s coast. Flooding scenarios
for the forecast increase in sea levels by 60 cm until the end of the century, i.e. 120 cm at extreme tides were also
tested. High vulnerability of the costal settlements on Krk Island was confirmed, primarily due to flooding exposure. It
is necessary to create databases with sufficient accurate data on land and seafloor relief, geological composition fabric
and oceanographic characteristics to determine the degree of vulnerability and hazard and risk mitigation measures.
