According to previous experience, it was very difficult to collect the bed load data in weir NO2 especially during Typhoon perioids. Total station was applied to measure the micro-relief of channel for calculation of sediment yields. G.I.S. software is also used for calculation on the total volume of the bed load. There is about 60.78 cubic meters deposit in the period from June 1999 to March 2000. Sediments deposition change 1 the micro-relief of channel dramatically according to the detailed surveying. In the future, repeated surveying could be a good way for calculation and evaluation of sediments in weir NO 2.在本年度的研究中，主要是觀測哈盆溪一號與二號量水堰上游集水區的降雨以及沖蝕。對於二號量水堰上游集水區的沖蝕量觀測在本年度採用全測儀配合地理資訊系統軟體，而一號量水堰上游集水區的沖蝕觀測則以收集的方式進行。在全測儀的量測結果方面，估計在1999年六月至2000年三月之間，上游河道共搬運了60.87立方公尺的沈積物到二號量水堰上方堆積，使量水堰上方人工河道區域的微地形有許多改變，造成河道中的沙洲，並且使河川的流路改變，這個新的觀測方式可以在未來繼續進行，並且進行相關的分析與評估。application/pdf31440 bytesapplication/pdfzh-TW國立臺灣大學地理環境資源學系暨研究所Total stationChannel microreliefG.I.S.sediment yields全測儀河道微地形地理資訊系統reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/11382/1/892621B002014.pdf
