ON-SITE AND NUMERICAL MODEL STUDY TO ESTIMATE THE SEDIMENT PARTICLE BY CULTIVATION OF SEA BOTTOM AS THE NUTRIENT SUPPLY TECHNIQUE

Abstract

 The field observation and the numerical model study was carried out to comprehend the sea-cultivated sediment particle behavior. It became clear that the curled up soil particles were transported downstream and diffused to the water mass. From the hydrodynamic model including turbidity calculation, the distribution of sediment particle was strongly effected by the seabed topography and the operation of sea cultivation during the flood to high tide on the spring tide period was efficient at the Ieshima Islands.
