Large stones and rocks lie in mountain rivers. The river is steep and the rocks form lines that reduce the energy of the water flow. Strong upstream currents are generated upstream of these rows of rocks, and strong downstream currents are generated downstream of them. Playing in these areas is fun, but also dangerous. Therefore, wear a life jacket and play near the water!
山間の河川には,大きな石や岩が転がっています.川は急こう配であり,岩が列をなして,水流のエネルギーを減らします.このような岩の列の上流では強い上昇流が,下流では強い下降流が発生します.このような場所で遊ぶと楽しいですが,危険でもあります.そのため,ライフジャケットを着て,水辺で遊びましょう!
