This paper deals with the applications of intersecting flows for the improvement of water environments in water reservoirs. First, the present authors’ research results are summarised for flow characteristics in intersecting channels placed in horizontal or vertical positions. All physical phenomena involved are identified and their mechanisms are explained. Subsequently, appropriate methods are obtained for solving the problems of stratified water and eutrophication in water reservoirs. A novel drainage system is developed and a particle ejection experiment for sediment flushing is investigated utilising a reservoir model with glass beads replacing sands. Flow visualisation and measurements are used in each experiment. The study has concluded that intersecting flows are suitable for solving water environment problems in water reservoirs.Keywords:intersecting flow; water reservoir; water environment problem; drainage system; sediment flushing
