| 中文摘要 | 本研究分析石門水庫上游集水區的水文和泥砂資料,探討降雨逕流關係及水文因子對集水區泥砂生產特性之影響,並建立石門水庫集水區之泥砂生產量推估式。本研究發現石門水庫集水區之年流量的變化受年雨量影響很大。年懸浮質含量(Q���腹^與年最大洪峰流量(Q�d)呈正相關但相關係數並不很高。 本研究結果顯示在影響石門門水庫集水區泥砂產量之水文氣象因子中,與超過某一定量之降雨量及逕流量有最密切之正相關;亦即石門水庫集水區之泥砂生產量與颱風所帶來之與暴雨直接逕流量有最密切之關係。本研究結果有助於用降雨或流量因子來估算集水區流砂產量。 |
| 英文摘要 | Using available data from gauged subwatersheds in the Shimen Reservoir basin in northern Taiwan, this study investigated relations between sediment production and watershed hydrological characteristics. The results indicate that the variations in annual runoff were mainly governed by variations in annual rainfall. Suspended sediments of six gaged sub-watersheds correlated well with annual peak flows. However, low coefficient of determination (r��) suggested that there are other influencing factor. Among hydrological factors, the accumulated amounts of daily rainfalls/streamflows exceeding certain values appear to relate most closely to the amounts of watershed sediment yields. The results are useful in predicting sediment production using either rainfall or streamflow parameters as predictors. |
