SIS-VIS project represents the finalization of hydrogeological research necessary for the creation of the basic hydrogeological map (OHGK) of the island of Vis. Data collected through previous projects will be systematized and published, and additional data needed for OHGK will be collected. Four-year hydrogeological and hydrochemical observations will be conducted according to the already established continuous and periodic observation scheme, which will provide a representative set of necessary data. New pumping tests will be carried out for better determination of hydrogeological parameters, as well as supplementary structural-geological research in places where a lack of data is determined. Diffuse outflow from the island's karst aquifer via submarine springs (vruljas) will be investigated using remote sensing by thermal camera and marine geophysical research by side-scan sonar and sub-bottom profiler. Research results will be published in scientific papers, doctoral dissertation and OHGK of the island of Vis and its explanatory notes.

Vis is a remote island that relies exclusively on its own karst aquifer for public water supply, so the applicability of the research results will be significant for the long-term sustainable water supply of the island, possible new wells and the establishment of an early warning system for seawater intrusion, as well as for better valorisation of the hydrogeological heritage of the island, which is part of the UNESCO Geopark Vis Archipelago.
