Summary: | 博士 === 國立中央大學 === 土木工程學系 === 103 === The Shimen Reservoir is the major reservoir in northern Taiwan to serves a number of purposes, including irrigation, hydroelectric power, domestic and industrial water supply, fold prevention and sighteeing. The average year-supply of the last decade was about 8x108 m3. The amount of inflow in dry season or wet season was evidently different. The inflow in dry season account for 21.3% of the average year-inflow and with the shortage of 54.51 million m3 by the water resource plan in the last decade. If the storage was insufficient by the end of wet season, the potential risks of water shortage would be increasing. This study used the CROPWAT model and Irrigation Plan to analysis the effect of adjusting the farming schedule, irrigation interval, and rotation interral on irrigation management in dry season. And use the variation data of hydrological and meteorological parameters estimated by TCCIP to simulated the scenarios of water management of the Shimen Reservoir, to explore the impects of climate change on agricultural water management.
