Sažetak
Palata is a gravity spring which is tapped and included in the local water supply system County of Dubrovnik - Neretva, Republic of Croatia. This spring is situated on the Adriatic coast. Inflow area of this typical karsts spring is composed of the Mesozoic carbonate rocks and minor part of Eocene Age flysch deposits. Occurrence of the spring is related to the fault contact of upper Triassic dolomites and Eocene Age flysch deposits. The aim of this survey is to define location of waste management center and confirm hydrogeological characteristics in the watershed of the springs between Luka Slano and Rijeka Dubrovačka. Ground water flow is established by hydrogeological investigations with dye-tracing techniques, respectively. Dye-tracing was done with 48 kg Na-fluorescein which was poured into the pit Zadiljke. Observed springs are situated on the Adriatic coast at the distance of 6, 0 - 17, 2 km from the pit Zadiljke. The apparent velocity of the monitored spring Palata is 6, 07 cm/s. There is no confirmed connection between the pit Zadiljke and springs Usječenik, Studenac and Ombla by ground water analysis. Investigation showed that the watershed of the spring Palata does not belong to the springs: Usječenik, Studenac and Ombla. Results of the ground water dye-tracing test shows that the pit Zadiljke is directly connected with spring Palata in the settlement Mali Zaton.
