Abstract
Changes in the components of the hydroclimatological water balance over the last 100 years were investigated in Tsu City in the central part of Japan as a case study. Annual potential evapotranspiration has increased over a long period of time. Smoothed secular changes in the difference between the annual values of precipitation and potential evapotranspiration are analogous to those in the annual precipitation. The difference between annual precipitation and annual potential evapotranspiration is inclined to be below the average since the latter half of the 1920s, but the imbalance has increased over the last few years. A trend curve of the long-range changes in the annual runoff ratio is dominated by annual precipitation. The average annual runoff ratio for each ten years has a tendency to decrease during the last few decades.
