人造淡水湖(児島湖)における塩分の収支推定について(その1) ―樋門,閘門を通しての塩分の出入―

Abstract

After closing of the mouth of Kojiina bay by an artificial bank, the salinity ofwater in the closed lake decreased promptly and the salinity distribution approaches afinal state. In order to study the salt balance in the Kojiina lake, the investigation oninflow and outflow of salt was carried out.Especially, the quantity of salt discharging through the sluice and inflowing fromthe lock gate was estimated by the observations of salinity and current velocity and bysimple calculations and model experiments.
