Abstract
This paper discusses field observations and model results for temperature and concentrations of dissolved substances in Myojin-ike, a saline lake. Myojin-ike is itself composed of three smaller interconnected basins, the largest of which is connected to the sea of Japan by a pipe. Results from water quality analyses and hydraulic measurements indicate that there is a fair amount of exchange of nutrients between the lake and sea and from groundwater. A simple model is presented that incorporates these exchanges. Calculated and observed concentrations for salinity, SiO2, PO4-P and [NO2-N+NO3-N+Org. N] show good agreement.
