中文摘要 | 本文之主要目的在於研究花蓮縣土石流發生處逕流歷線之特性,選定之區域為發 生過土石流災害的花蓮縣秀林鄉銅門及榕樹兩地。 本研究為了要進行人工降雨之模擬而成功的的完成改良式 Shelton et al. ( 1985 )人工 降雨機, 並將三種大小不同之 Fulljet 噴頭在不同水壓及空壓下加以率定,率定項目為降 雨強度及其均勻性。在定量模型研究方面,本研究之目的在藉著本研究所建立之模型及人工 降雨之模擬來推算銅門地區土石流發生處上、中、下游溪谷斷面之單位逕流歷線,求取該地 區上、中、下游之降雨逕流歷線。此結果可當作土石流定性模型供給流量之參考。 |
英文摘要 | This study aims mainly at characteristics of runoff hydrography at the places in Hua-Lien, where debris flows have ever occurred. Two sites at Toun-Men and Zoun-Shuh in Shou-Lin, Hua-Lien were selected. In this study, to simulate rainfall, a rainfall simulator was successfully designed, constructed, calibrated and operated by modifying the simulator developed by Shelton et al. (1985). While calibrating, three different sizes of fulljet nozzles were used, different air and water pressures were applied. The calibrated items were rainfall intensity and its uniformity. To assess the unit hydrographs on the cross-sections at upper, middle and down stream of the watershed at Toun-Men, where the debris flow occurred, a watershed model was established, and simulated rainfall was applied. When the rainfall (the typhoon called Aofeili, occurred on June 22, 1990) which caused the debris flow was simulated, the rainfall-runoff hydrographs on three cross-sections were obtained. Above results are useful for determining the chute test's simulated flow rate in the laboratory. |
