Research Abstract

Evaporation rates of water surface in Nakazato Reservoir, Lake Komadome and Lake Toya were determined from meteorological Parameters of water and air temperatures, air humidities and net radiations. In Lake Komadome, the water balance was also estimated from the date of precipitation and water level. And the evapotranspirations were observed in the fields of paddy, tea plant, bamboo grass and bare land. The results were summarized as follows ;
(1) Daily evaporation rates during 175 cold days in Nakazato Reservoir varied from-1.27mm/day to 8.46mm/day and average was 1.80mm/day. (2) Evaporation rates during 6 months in warm season in Lake Komadome were from 2mm/day to 6mm/day. The water level in the lake were determined by the balance of the inflow from basin and the groundwater discharge from lake. (3) Daily evaporation rates in Lake Toya was 2.6mm/day in summer season, and the annual evaporation rate of 820mm was estimeted by the data of netradiation and water temperature. (4) The rates of evapotranspiration in paddy field was 5.3mm/day and it was the largest value in in the differnt land surface. (5) As the results, it was considered that if the evapotranspiration rate in the basin was changed, the water balance in land water would be changed, and the mean water level would be different level.
