Abstract

Hydrological assessment of the effect of water utilization on a lake water budget isindispensable for proper water management. A model to estimate lake water level was developed for Lake Ikeda, Japan, and was applied to investigate the lake water budget and to examine the effect of agricultural water management on the lake water level. The calculated lake water levels agreed well with the measured levels for 1983-1999. The lake water level is generally highest from September to October and lowest in March, and is characterized by seasonal changes in the water budget components. Three simulations under hypothetical hydrological conditions revealed that river water supply in the agricultural water management system effectively compensates for the decrease in lake water levels caused by agricultural water use.
