Cave diving explorations in the spring of Rjecina.
Abstract:
The spring of Rjecina is one of the biggest springs in the area of Dinaric Karst. It is situated approximately 10 km in the North from the town of Rijeka. As a part of the last hydrogeological explorations cave diving team of SK from Zagreb performed the cave diving investigation of the water covered cave canals of the spring. The total length of the spring karstic system has been increased on 260 m with final reached point on depth of 50.5 m. Based on the results of cave diving exploration as well as on analysis of all the former investigations the major conclusions can be made. First of all, upper and lower inlet canals of the spring are hydraulically quite separated. Further, it can be supposed that in the background, they are in continuation of the separated retention areas. In the dry period both underground canals have no direct connection with the retention areas and the water present in the spring is only the rest of the last flowing out "captured" in the underground caves. It means that the possibilities of obtaining considerable quantities of the groundwater in the spring itself (in the dry period) by overpumping, i.e. by considerably lowering the water level in spring, are very small and the investigations should be directed towards another solutions. Although the mentioned conclusions are based on the data obtained at complete hydrogeological processing, it is important to stress the considerable contribution of the speleologic and cave diving investigations. It has been proved that these investigations are very important in karst areas. With undoubtedly important information concerning morphology of underground, which is the supposition for planning and performing the investigation works and other operations, speleologic and cave diving observations con contribute better understanding of the complex hydrogeological relations.
