Hydrographic Institute of the Republic of Croatia has set up a new permanent tide gauge station at Rijeka. The station is fitted with radar sensor for measuring sea level heights.

The data obtained from this tide gauge station will be particularly important for regulation of navigation in the port of Rijeka. In addition to enhancing the safety at sea, it will facilitate the production of new navigational charts of a wider sea area of Rijeka. The collected data are important for studying and estimating the rising trend of mean sea level, as well as for determining reference surfaces for the hydrographic and land surveys.

The HHI will continue to work towards expanding the existing tide gauge network.
