中文摘要 | 分水設施為灌溉管理上之重要工程設施之一,目前河川式引水灌溉之支分線系統內分水設備,遭遇以下問題(1)進流量不穩定—流量變化很大(2)務農人口外流—人工短缺(3)經費有限未能全面現代化,以致於現地常見之調節式分水閘門分水工未能發揮其應有機能。本研究以坡度、灌溉水頭、流況、能量、動量及分水機能針對(1)現地常見之分水工—閘門分水工問題之探討(2)據有優良分水機能與分水經驗—長源圳之比例分水工(3)具有實用效率—茄苳腳圳內之特殊分水工,故定性之分析與分水技術之調查研究;發現定性比例皆水工之改善方案與其應用於灌溉系統之控制調節上,可十是供目前河川式甲水灌溉之支分線系統內分水設施設計與修繕之參考,值得進一步對定量作分析與研究。 |
英文摘要 | Division works are one of the important irrigation facilities for water management. At present, there are several problems encountered during implementation of water distribution in the secondary canals of run-of-river irrigation system, namely, (1) unstable division with great variation, (2) manpower shortage due to outflow of farm labors from rural area, and (3) limited fund for full modernization. As a result, many division structures, installed with gates for regulation of water, have not yet fully functioned as they are expected. In consideration of such factors as canal, slope, head difference, flow condition, energy, momentum and function of water distribution, this study focused on the following three cases: (1) gated division structures commonly used, (2) well functioned and well proportioned division structure on Changyuan canal System, and (3)specific and practical division structure on Chiatungchiao Canal System. After investigating the water distribution procedures, studying the existing problems and making qualitative analysis, it was found that the well proportioned division structure could be further improved and then adopted for control and regulation of irrigation in the canal system. Results of this study could be sued as reference in the future design and maintenance improvement of division structures of the run-of-river irrigation system. However, further study and quantitative analysis in this respect are worth to be done. |
