Tracer test dataset conducted on Dinaric karst island aquifer
Description
Tracer test was conducted by injecting Na-fluoresceine into a borehole located approximately in the center of the island Vis in the Adriatic Sea (Croatia). Only 0.4 kg of dye was used as the borehole is located at the “Korita” pumping site which is the only source of fresh water on the island. Dye was recovered only at nearby boreholes, although coastal springs were monitored for two months. The dataset includes recovered dye concentrations from two boreholes with a depth of approximately 150 meters. Their coordinates and map with all sampling locations are also provided. The purpose of the tracer test was for delineating the catchment of the “Korita” pumping site and determining the maximum apparent speed of the dye, as is required by Croatian legislation. Island Vis is composed mainly of karstified carbonate rocks and belongs to the Dinaric karst region, locus typicus for karst landforms. The provided information can be used for determining the hydraulic properties of its aquifer and for research of karst in general.
