Abstract
The authors make a field study on hydrological-environmental aspects on springs in upper region of Noh river. Water quantity and quality of 8 springs and Noh river had been observed once a month for 6 months (Aug., 1987-Jan., 1988). At first, it is made clear that the discharge of Noh river mainly consists of the discharges of the above springs. Discharges of several springs have a high correlation and linear regression analysis is done. And it is made clear that the discharges of 3 major springs consist of about 80% of Noh river's discharge. It is also shown that correlation between electric conductivity and concentration of Cl is high and that regression line of those matters is obtained.
