本文探討人工渠道及自然河道的水力半徑 及水力深度 之比值 。由人工渠道的分析中可知比值 和渠道的幾何形狀及水深有很密切之關係;當深寬比(水深和渠寬的比值)愈大時, 值愈小。本文並以曾文溪及高屏溪為例,分析自然河道 值的特性。本文分析曾文溪二溪大橋、左鎮、玉田及新中等四個測站之斷面及流量量測資料,結果顯示曾文溪水力半徑和水力深度之比值 的範圍大約介於0.70至0.95之間,但在低流量時 值略高一些,大約為0.9,而在高流量時 值約為0.8。依據高屏溪三地門、六龜及新發大橋等三個測站之斷面及流量量測資料的分析結果顯示,高屏溪的 值範圍大約介於0.80至0.95之間,但高屏溪的 值和流量大小之關係不明顯。
The ratios of hydraulic radius R and hydraulic depth of artificial channels and natural rivers are investigated in the present study. The ratio is dependent on the channel geometry and the flow depth. The larger the depth-width ratio ( the ratio of flow depth and channel width ) the smaller the value. The -values for two natural rivers, such as Tsengwen and Kaoping rivers, are also studied. Based on the measured data of cross-sections and flow discharges of Er-Si, Zuo-Jhang, Yu-Ten and Hsin-Chung stations in Taengwen river, the -values for Tsengwen river is about 0.70~0.95, and the ratio has higher value as the flow discharge is lower. For lower flow discharge , the -values is about 0.9, while for higher flow discharge , the -values is about 0.8. Based on the measured data of San-Ti-Men, Lu-Kwei and Lao-Nung stations in Kaoping rivers, the values of is in the range between 0.80 and 0.95, and it seems independent of flow discharge.
