臺灣北部地區(新竹、桃園、臺北)之降雨分佈雖較南部地區來的平均，但降雨事件仍多集中發生於豐水期，且隨著竹桃北地區之經濟蓬勃發展與人口快速增加，使得民生與工業用水量大幅增加，導致農業灌溉用水量吃緊，仍會有乾旱與水資源匱乏的事件發生。為因應水文與供需端之變化，本子計畫一於第一年與第二年分別針對竹桃北地區進行現況供水模擬與分析，並建立竹桃北地區集水區降雨逕流模式與灌溉用水水量推估模式。第三年加入氣候變遷因素，結合前兩年已完成之降雨逕流模式與灌溉用水量推估模式，以估算未來流量與灌溉用水量資料；並將模式推估出之未來流量資料與採用新方法經驗模態分解法推估出之流量資料進行比較，探討該方法之適用性；最後，結合前兩年研究結果與其他子計畫產出結果，如生態用水、氣候變遷、農業用水調整、標的用水移用機制甚或地下水管理等多元利用之水庫調配策略，進行不同調度策略下各需水情境之供需分析。 The distribution of rainfall in northern Taiwan (Hsinchu, Taoyuan, Taipei) is more even than in southern Taiwan, but the rainfall events are still mostly concentrated in the wet season. With the vigorous economic growth and rapid population growth in this areas, the people's livelihood and industrial water consumption have risen sharply, leading to tight water supply for agricultural irrigation and frequent occurrence of drought and water scarcity. In response to changes in water supply and demand, the project plans to conduct a current water supply simulation and analysis for Hsinchu, Taoyuan, Taipei region in the first year and the second year, and establish an suitable rainfall runoff model and irrigation water estimation model.In the third year, by considering climate change, combined with the completion of the first two years' models to estimate the flow and irrigation water consumption in the future. In addition, a novel Empirical mode decomposition-based synthesis method for nonstationary sequences is proposed for solving problems that cannot be solved by time series modeling approaches in the past. A comparison between runoff model and EMD-based method will be made. Finally, based on the results of the other subprojects, such as ecological water use, climate change, agricultural water use adjustment, groundwater management, alternate supply and demand analysis will be taken into consideration.
