The approach adopted involves the field deployment of a tracked underwater ROV (Remotely Operated Vehicle) equipped with jetting and imaging devices. This ROV will have the ability to move underwater along the river or seabed, even in the presence of currents. Its function will be both to passively monitor and to actively probe near-bed sediment processes. The start-up phase of the programme, supported by a one-year grant from the NSC, focused on the following tasks: 1) the design and construction of the ROV platform (vehicle body and propulsion); 2) exploratory modelling and experimental testing of the underwater jetting device; 3) development of a vision system for ROV positioning and sediment bed observations; 4) preliminary lab and river assessments of the strategy. Future work will seek to integrate these components into an operational system.application/pdf3953540 bytesapplication/pdfzh-TW國立臺灣大學水工試驗所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9922/1/922211E002040.pdf
