中文摘要 | 臺灣地區時常發生颱風水患與土石災害,因此探討水文環境有助於臺灣地區環境永續經營與管理,本研究主要目的是分析1970年至2009年東港溪潮州流量測站、花蓮溪花蓮大橋流量測站、花蓮溪仁壽橋流量測站與秀姑巒溪瑞穗大橋流量測站河川流量、河川含砂量與河川輸砂量,建立河川流量-河川含砂量迴歸模式。本研究發現東港溪潮州流量測站、花蓮溪花蓮大橋流量測站、花蓮溪仁壽橋流量測站與秀姑巒溪瑞穗大橋流量測站時間累積0.5%,河川流量累積達13%-17%,花蓮溪仁壽橋流量測站河川流量累積百分比為最大(17.34%),其次為秀姑巒溪瑞穗大橋流量測站(13.98%),再其次為東港溪潮州流量測站(13.84%),花蓮溪花蓮大橋流量測站河川流量累積百分比為最小(13.12%),時間累積1%,河川流量累積達18%-25%,時間累積5%,河川流量累積達34%-47%,時間累積10%,河川流量累積達43%-58%。東港溪潮州流量測站、花蓮溪花蓮大橋流量測站、花蓮溪仁壽橋流量測站與秀姑巒溪瑞穗大橋流量測站時間累積0.5%,河川輸砂量累積達34%-72%,花蓮溪花蓮大橋流量測站河川輸砂量累積百分比為最大(71.53%),其次為花蓮溪仁壽橋流量測站(66.97%),再其次為秀姑巒溪瑞穗大橋流量測站(64.44%),東港溪潮州流量測站河川輸砂量累積百分比為最小(33.88%),時間累積1%,河川輸砂量累積達47%-81%,時間累積5%,河川輸砂量累積達76%-92%,時間累積10%,河川輸砂量累積達84%-96%。東港溪潮州流量測站、花蓮溪花蓮大橋流量測站、花蓮溪仁壽橋流量測站與秀姑巒溪瑞穗大橋流量測站河川流量累積1%,河川輸砂量累積達4%-13%,花蓮溪花蓮大橋流量測站河川輸砂量累積百分比為最大(12.52%),其次為秀姑巒溪瑞穗大橋流量測站(11.74%),再其次為花蓮溪仁壽橋流量測站(10.08%),東港溪潮州流量測站河川輸砂量累積百分比為最小(3.76%),河川流量累積5%,河川輸砂量累積達15%-40%,河川流量累積10%,河川輸砂量累積達26%-63%,研究結果可供相關單位參考,期望有助於臺灣地區水文環境永續經營與管理。 |
英文摘要 | Typhoons and floods often occur at Taiwan. Therefore, to examine hydrological environments of Taiwan is helpful to the sustainable development and water resource management of Taiwan. The aim of this study is to analyze stream discharge, sediment content, and suspended load of the Chao Chou station at Tung Kang Creek, the Hua Lien Bridge station at Hua Lien Creek, the Jen Shou Bridge station at Hua Lien Creek, and the Jui Sui Bridge station at Hsiu Ku Luan Creek in the period of 1970 to 2009. This study uses the rating equations to estimate daily average sediment content from daily mean discharge. Results show that stream discharge cumulated 13%-17% when time cumulated 0.5%. Stream discharge cumulated the most at the Jen Shou Bridge station (17.34%), the second at the Jui Sui Bridge station (13.98%), the third at the Chao Chou station (13.84%), and the least at the Hua Lien Bridge station (13.12%). Stream discharge cumulated 18%-25% when time cumulated 1%. Stream discharge cumulated 34%-47% when time cumulated 5%. Stream discharge cumulated 43%-58% when time cumulated 10%. Results show that suspended load cumulated 34%-72% when time cumulated 0.5%. Suspended load cumulated the most at the Hua Lien Bridge station (71.53%), the second at the Jui Sui Bridge station (66.97%), the third at the Jui Sui Bridge station (64.44%), and the least at the Chao Chou station (33.88%). Suspended load cumulated 47%-81% when time cumulated 1%. Suspended load cumulated 76%-92% when time cumulated 5%. Suspended load cumulated 84%-96% when time cumulated 10%. Results show that suspended load cumulated 4%-13% when stream discharge cumulated 1%. Suspended load cumulated the most at the Hua Lien Bridge station (12.52%), the second at the Jui Sui Bridge station (11.74%), the third at the Jui Sui Bridge station (10.08%), and the least at the Chao Chou station (3.76%). Suspended load cumulated 15%-40% when stream discharge cumulated 5%. Suspended load cumulated 26%-63% when stream discharge cumulated 10%. The results are helpful to the sustainable development and water resource management of Taiwan. |
