Some locations in rivers are known as dangerous spots, where water-related accidents occur repeatedly. One possible cause is the formation of hazardous vortices and downward currents in areas where rivers bend sharply or where the riverbed suddenly becomes much deeper.
Our laboratory is initiating a research project to evaluate drowning risks at these locations. Using a coupled human–fluid simulation model, we aim to reproduce actual hazardous river locations in a computer simulation and assess the risks they pose to people in the water.
