Abstract: Rafting as one of the recreational hydraulic activities is a popular river recreation activity and is in demand by the community. However, the risk of accidents often occurs, especially when the boat passes through strong currents and hydraulic jumps, which have the potential to overturn the boat and endanger tourists. The purpose of this study was to observe the flow profile and hydraulic jumps that have a risk of accidents at the rafting location. The study was conducted on the Elo River, which is actively used for rafting with more than twenty thousand visitors per year. Based on field observations, there are 3 locations) that have a risk of boat accidents overturning/overturning, passengers falling/thrown from the boat, namely at the Keriting Location, the Jeram Panjang Location and the Penyempitan area. At these locations, drops and hydraulic jumps are found. From the measurement, in the flat Elo River channel, the flow velocity is very slow with a velocity range of 0.28m/sec-0.83m/sec), in the Elo River channel which has waterdrops, hydraulic jumps, the flow velocity reaches the maximum value 3 m/sec. The level of risk increases during large discharges (rainy season), with current speeds that produce strong jumps that cause boat instability. Whitewater rafting tourism is a recreational hydraulic that can be developed to support sustainable river management in the aspect of economic, environmental and community empowerment benefits, and also to support the achievement of Sustainable Development Goals (SDGs), such as Goal no 3 Good Health and Well-being, Goal 6 Clean Water and Sanitation, Goal 8 Decent work economic growth, Goal 11 Sustainable Cities and Communities, Goal 13 Climate Action, Goal 14 Life below water and Goal 17 Partnerships for the Goals.
