Sažetak
This study gives the systematic insight into sedimentation processes in the Kaštela Bay as a whole system instead of at the isolated individual sampling stations. Its results are equally applicable to other aquatic environments with comparable processes and sedimentation environments. Vertical depth profiles of Cs-137 massic activities were used to: i) Study sedimentation processes ; ii) Distinguish sedimentation conditions in different parts of the Bay ; iii) Partly determine the pathways of the terrigeneous sedimentary material input into the Bay. It was found that the continuous, undisturbed sedimentation, with only occasional sedimentation anomalies, takes place in the central and south parts of the Bay, while the sedimentation conditions in the west part of the Bay are more complicated. West part of the Bay is characterized by the extremely slow sedimentation of the coarse grained sediment or even by the erosion and selective resuspension of the fine grained particles followed by the resedimentation in other parts of the Bay as the predominating processes. It was also observed that the upper 10 cm of the Kaštela Bay sediment are the most exposed to homogenization. East part of the Bay is strongly influenced by the Jadro River and anthropogenic activities, which is reflected in higher 137Cs massic activities, strong sediment mixing, and increased sediment input.
