| Research Abstract |
To quantify the material budget focusing on fine scale sand in coastal water body, we developed monitoring systems and conducted the field observations. From comparison of monitoring results of water qualities in urban area, SS increased about 10 times immediately after rain. On the other hand, turbidity in mangrove estuaries didn't change soon and the rate of increase was remarkably smaller than in urban river. In addition, TN (Total Nitrogen) and TP (Total Phosphorus) also had same tendencies. It showed that mangrove natural rivers moderate excess outflow of solids and nutrients to coastal area. Our observing system, successfully captured periods of timing, rainfall events, and subsequent changes in SS and nutrients in coastal region.
