碩士 / 國立臺灣海洋大學 / 海洋環境資訊學系 / 99 / This study aimed at the effects of the sea water surrounding the outlet in Yuanshanzih Flood Channel during various climate conditions, including summer, winter and typhoon invaded during 2006-2008. In the upstream of Keelung River, the total suspended solid, turbidity and chlorophyll were significantly increased with increasing rainfall intensity (p< 0.05). Meanwhile, nutrients including nitrate, phosphate and silicate were increased with increasing rainfall intensity.
The flooding water reached to 16.13 Mtone during Krosa invaded in 2007. It almost reduced 65% flooding water in upstream of Keelung River. This result indicated Yuanshanzih Flood Channel had expelling flood function in the rainy season. But it also brought a large number of sand to East China Sea. The turbidity in Keelung River was below 1000 NTU at normal condition. But while the rainy season or typhoon attacked, the turbidity in Keelung River will increase rapidly and most over 20000 NTU. The suspended solid and turbidity caused by flooding water and pollute the surrounding sea water.
