中文摘要 | 臺灣由於現實需要興建許多防砂壩,並為配合改善魚類生態環境,暢通魚類之迴 游路線,而配置魚道。然所設計之傳統魚道,常因遭礫石撞擊阻塞而失敗。本研究主要針對 傳統防砂壩及魚道之缺失進行改良,主要改良項目包括防砂壩開口設計、複式排水斷面、魚 道之配置型式、鋼板柵分離礫石與水設計,以防止防砂壩魚道之阻塞。 |
英文摘要 | To improve the upstream channel ecological environment, many dams were constructed in Taiwan with fishways to provide necessary gateways for fishes to return to their original habitants. However, conventional fishways normally failed to function owing to the damage or blockade by boulders. Several improvements on fishways and check dams are investigated herein for exploring new research directions for blockade-prevention techniques, including rectangular opening to channel bed in the middle of dam, compound spillway of check dam, special layouts of fishway, and steel screen, for sparating coarse sediments from water. |
