摘要

For the particular conditions of weather, geography, and land use, watershed development is an unavoidable tendency for contemporary Taiwan. Several engineering measures are applied in the field to keep the same or lower peak flow compared to that of the watershed before development under specific design frequency rainfall. For the last decade, several theses about flood-detention dam, modified from traditional check dam with a narrow and deep opening in the center, were completed under the guiding of second author. This paper tries to conclude the characteristics of this particular flood-detention dam from those experimental studies. Comparisons with detention basin, which is used for flood control at urban area in U. S., are also made to show the essential differences between these two methods. Finally, the possible future researches are discussed in the paper.

由於氣候、地質、土地利用等因素，集水區開發在臺灣變成一種無法避免之趨勢。爲降低集水區開發後之洪峰流量，數種工程方法被運用於現場。過去數年來，許多有關滯洪壩之試驗研究在第二作者的指導下陸續完成。在本文中，作者嘗試從這些研究成果歸納出有關滯洪壩的水文及水力特性。在美國都市中常見的滯洪池，在文內被用來與滯洪壩作一功能性的比較。最後，今後之可能研究方向也作一簡單討論。
