碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 95 / Estuary is an area with very complicated characteristics, which is mainly affected by tidal dynamics. The salinity of a tidal river is influenced by tidal characteristics where fresh water meets salty water and thus causing the complexity.
The Love River in Kaohsiung, Taiwan, has been chosen as an study area for the researches describing in this thesis work. The four sampling stations cover the tidal zone of the Love River. Through frequent sampling, which corresponds to spring tides, neap tides and even during complete tidal cycles, the water quality and the variations of particle circulation in estuary area can be comprehended better.
The distributions of the nutrients in the river are different during spring tides and neap tides. Nitrite and nitrate are mainly come from the upriver or generated by the nitrification within the river. In addition, the results from the whole tidal cycle experiments show that high flow rate occurs at the bottom during the period of turning tides, which caused higher SPM concentrations in the bottom layer. This is mainly due to the accumulated agitations at the river bottom were resuspended by the strong currents.
Analytical results from a Pearson product-moment correlation has shown that the SPM concentrations in the bottom water partly come from the resuspension processes of bottom sediments. Nutrients accumulated in the bottom sediments were released into the water column by the SPM resuspensions. The result of PCA shows that the changes of tides affect the distribution of salinity has a strong negative correlation with turbidity and SPM. It also shows that tides not only have a quite obvious influence on suspended particle matters but also dominate the distribution of suspended particle matters through out the Love River.
