The sediment transportation is divided to three main parts, dissolved load, suspended load and bed load. The results show that rainfall will affect the nature of river transportation. Base flow transports much of the dissolved load. But when it rains, the river water level goes up and stream flow accelerated, which makes the ability of river transportation. At that time, river moves much of the suspended load and bed load, and the dissolved load concentration goes down. This shows that the 1 rainfall controls the nature of the river transportation. Drainage area of weir NO1 is also being analyzed. There are two peaks, which shows the orientation of channel sections. The coincidence of the river channel with geological strike, dip of bedding and joints. This coincidence shows that geology controls the spatial arrangement of fluvial network.application/pdf611182 bytesapplication/pdfzh-TW國立臺灣大學地理環境資源學系暨研究所暴雨溶解質推移質懸移質StormDissolved loadBed loadSuspended loadreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/29630/1/882621B002018A10.pdf
