Abstract
|
|
|
To investigate the influence of water area calmness on the red tide development, runoff phenomena due
to antecedent precipitation of red tide development day were analyzed. There were examined the water quality
variation properties at about the same time of the red tide develop. The red tide was developed when the
stage and discharge nearly had not changed. It was estimated that the stability of particle behavior in the mouth
of river effected on the red tide develop. Also, the concentrations of CODMn were increased about 241~629%
when the red tide developed.
