IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Spatial-temporal fluctuation of salinity in lake jusan
Author : MIKIO SASAKI(1), HITOSHI TANAKA(2) & MAKOTO UMDA(3)
ABSTRACT
The present study aims to investigate the characteristics of the motion of salt water and to show temporal fluctuation of
salinity in Lake Jusan located in the estuary of Iwaki River in Aomori Prefecture, Japan. Lake Jusan is the best
productive water area of the shellfish, corbicula, in Japan in 2013. Then, the lake is very important in Aomori Prefecture
as corbicula¡¯s home. Then, it is important to make clear the characteristics of the motion of salt water in the lake. In the
present study, observations for the motion of the salt water going up to the lake and going down from the lake to the sea
were carried out from June to October. The time change of the salinity distribution in a perpendicular direction is
investigated in the field observation in the present study. The vertical distributions of the salinity are shown clearly by
theory and observations. And the present study shows that the theory given by Sasaki, Tanaka and Umeda can generate
well the movement of the saltwater in the lake.
