中文摘要 | 乾旱是無可避免的自然現象,以蓄水設施貯蓄豐水期水量提供枯水期使用是最有效的長期性措施之一,但不預期的水文乾旱情況可能使水庫供水量無法滿足既定的計畫需水量。本文研究重點即為探討乾旱時期不同水庫供水策略對缺水之影響,所探討的水庫供水策略除運用規線、標準操作策略、定率動態規劃模式及序率動態規劃模式外,本文亦以水庫蓄水量及入流量轉換機率對計畫需水量的關係定義一水庫供水指數,除可代表不同時期水庫供水潛能外亦可作為水庫供水的依據。不同的供水策略所導致不同的水庫營運成效將以缺水特性來評估,本文所使用於分析的缺水特性包括缺水量、缺水延時及缺水頻率在單一缺水時刻、缺水事件及整體時程的相關缺水指數。文末則以簡化的石門水庫單目標供水系統為例說明不同的供水策略在乾旱時期的缺水特性。 |
英文摘要 | Droughts are natural and inevitable phenomena. Storage facilities are considered as one of the most effective and long-term measures to regulate surface water. However, unexpected droughts often cause the water supplies insufficient to meet the predetermined target in a specific water supply system. In this study, the effects on water shortage for different reservoir releasing policies during drought are investigated. The reservoir releasing policies include rule curve, standard operating policy, deterministic dynamic programming, and stochastic dynamic programming. In addition, a reservoir supply index is defined in this study and used as a releasing indicator. The shortage indices used to evaluate the reservoir performance include shortage severity, duration and frequency. Finally, a simplified Shihmen reservoir system is used as a case study to illustrate the proposed methodology. |
