中文摘要 | 本研究以南投縣埔里鎮之墘溪為例,其屬性為區域排水,進行環境營造規劃。在研究過程中,收集包括集水區特性、既有構造物、空照圖、地形圖、河床質、水質和生態資源等基本資料,根據這些資料提出關於治理及環境營造願景的建議。其環境營造規劃主要有二個方向:一是入口意象、人行步道及休閒木椅之景觀規劃;另一是生態滯洪池之規劃,該池位於墘溪上游河段,長約200 m、寬約60 m、深約2.5 m。依照目前之規劃,該滯洪池可產生滯洪效果,約可將重現期距50年之洪峰流量減低為重現期距25年之洪峰流量,並且透過側堰之設計,大約10分鐘後滯洪池將會溢滿再流回墘溪主河道。除此之外,亦建議使用生態工程方式設計滯洪池,種植水生植物來改善水質,最後希望能結合治水理念與景觀規劃於墘溪之環境營造。 |
英文摘要 | The study is to introduce an example of planning and environmental construction concerning local drainage called Cian Creek located on Puli Town. In Nantou County, the administration property of Cian Creek belongs to local drainage or minor streams in Taiwan. In this research, we collected the basic data including watershed properties, existing structure conditions, aerial photographs, topographic surveys, particle size measurements, water qualities, and biological resources,etc. for further analysis. Based on these information, we proposed the following suggestions concerning controlling floods and also included future perspectives. The plan of environmental construction is divided into two parts: (1) the landscape scheme including the entrance image design, wooden sideway and view benches; (2) the ecological flood detention pond. The detention pond located on Cian Creek upstream is around 200 m long, 60 m wide, and 2.5 m deep. According to present planning, the detention pond can reduce the flood peak discharge of 50-year return period to a return period of 25-year peak discharge. About 10 min. later, the detention pond will be full and the flood can flow into the channel of the Cian Creek by the sideweir design. Besides, we also suggested the detention pond should be designed by the ecological engineering. In addition to preventing floods, the detention pond also has the functions of tourism and clarifying water quality by planting aquatic vegetation. Finally, the combination of hydraulic structures and landscape designs is presented for the planning and environmental construction of Cian Creek in the present study. |
