The artificial fishing mound (AFM) is constructed in deepwater by dumping a large amount of rubble or concrete blocks from a hopper barge to expand the fishing ground by uplifting the eutrophied water with the upwelling current generated on mound. In order to produce a designed geometry of AFM accurately and effectively, the operation management for the discharge position of barge, which is taken the transfer displacement of the falling blocks by the current into consideration, is required. In this study, the numerical simulation model to estimate the spatial deposition configuration of blocks dumped from barges has been expanded for the current field, and its practical adaptability has been verified by the field experiments. Furthermore, the management system on positioning of the barge, which is correspondent to the real-time utilization in the field, is developed by linking this simulation model and the inputoutput divisions for the ADCP measured data, the simulated shape of AFM and the position of barge.
