摘要


本研究於國立屏東科技大學水土保持綜合試驗區內,擇定一面積 0.8 ha之莿竹林集水區,分別設置自記式雨量計與量水堰觀測2018和2019年雨季期間之降雨量及逕流量,經比對不同降雨事件下之流量歷線和流量數據變化得知:當以無因次降雨強度公式及Horner降雨強度公式,推求2年重現期距之洪峰流量,分別為0.054及0.078 cms,對照觀測期間實測之最大洪峰流量為0.051 cms,顯示無因次降雨強度公式較適用於莿竹林集水區之洪峰流量估算,莿竹林地之逕流係數約為0.20~0.45之間。

The raingauge and weir for measurement were set up in a area 0.8 hectare of small watershed with thorny bamboo plantation of the comprehensive experimental zone for soil and water conservation, National Pingtung University. All the data of rainfall and runoff discharge were collected to estimate the hydrograph during rainy season from 2018 to 2019. The non-dimension’s and Horner’s rainfall intensity formula were adopt to predict maximum peak flow with recurrence interval in two years, had shown 0.054 cms and 0.078 cms, respectively. To contrast the two predictions with measured maximum peak flow could find non-dimension’s that was similar to practical condition. The runoff coefficient of bamboo plantation were about 0.20~0.45.
