The purpose of the present study is to make clear, by a series of investigations, the chemical and biological or ecological characteristics of this estuarine waters; the relation between the flow quantity in the River Nanakita and the vertrical distribution of particulate and dissolved matters. This paper consists of the foliowings; 1. The formation of saline layer of a surveyed point depending on the flow quantity in the River Nanakita. 2. The dependency on the water circulation and the vertical distribution of nutrient salts in this point. 3. The vertical distributions of particulate and dissolved organic matters depending on the degree of the flow quantity of the River Nanakita. 4. The vertical distribution of chlorophyll a, b and c in the ordinary degree of the flow quantity. From these results, it was clarified that the time of water circulation may be determined by the dependency on the flow quantity and the distance of sea water advancing into the river, and moreover, may determine the degree of flocculation, biological production and decomposition.
