Field Measurements on the Periodic and Spacial Characteristics of Thermal Structure and Water Quality in Lake Hibara

Abstract

This paper describes thermal stratification and water quality conditions in Lake Hibara. The period of the field measurements is from May to December in 1992. This study particularly investigates the relation between the characteristics of thermal structure and turbidity, dissolved oxygen, and electric conductivity, respectively. The main remarkable conclusions are stown in the following.
This lake indicates that the inflow and outflow gave the influence on water quality and water conditions. The measurement over the lake shows that electric conductivity of southern area in the lake had a tendency to have higher value than that in any other area.
