    Abstract: 亞臨界交匯流流況主要受支渠傳遞於主渠之主流向動量通量與主渠動量通量比及主渠下游流況之影響。大部份明渠交匯流之研究皆以主、支渠寬相等為主,且因交界面處主、支渠之水深約略相等,致動量通量比轉變成流量比之影響。一般之分析著重於流量比之影響,而對於其它影響參數則未曾探討。於主、支渠渠寬不等之交匯流況,除流量比及主渠下游流況外,主、支渠寬比及水深比亦造成極重大之影響。支渠傳遞於主渠之主流向動量除受支渠動量影響外,也受交匯界面平均流向角之影響。由因次分析知交匯界面平均流向角可表為主、支流流量、渠寬、水深與渠道交匯角之函數。因此可歸納知交匯流流況為渠道交匯角、主、支流流量比、渠寬比與水深比之函s數。本研究進行60及45交匯角之非等寬度交匯明渠流模型實驗與分析,流量比為0.375、0.500、0.630、0.770及0.900而渠寬比為0.46、0.72及1.00,共三十種流況。研究方法將包含(1)非等寬交匯明渠流一維解析模式之推導與分析、(2)非等寬交匯明渠流實驗及(3)與90及75交匯角之資料作進一步之比較與分析。
