摘要
以曾文水库集水区之主河道为研究对象 ,根据河道上防砂坝之河床粒径分布资料进行泥砂来源之粒径估算 ,且依来砂与河床之粒径概况探讨河道之泥砂之递移现象 ,针对集水区之冲蚀与崩坍比例进行初步研究 ,由分析结果发现曾文水库之淤砂其中 85 %源自于崩坍地 ,15
Based on the sediment distribution of check dams, this study studied the main channel of Tzeng Wen watershed and evaluated the sediment size of sheet erosion on hillslope. The equation of sediment delivery ratio had been build the sediment distribution of main channel and hillslope. Based on the sediment delivery ratio, 85% deposit came from landslide and 15% deposit came from sheet erosion in Tzeng Wen Reservoir.
