抄録: | Urban areas developing over inclined land near the base of mountains have sometimes been damaged severely by flood hazard with water and sediment overflowing from river channels.For the purpose of the prevention and mitigation of this damage, recent flood damage of river channels was researched to find out its essential aspects.Revetments destruction, one of its main aspects, have been studied by continuing fundamental experiments.Damage of revetments model can be determined by two factors, current velocity and bank slope.One of the other characteristic features is conveyance and deposition of floating wood by flood water.Mode and concentration of transport of floating wood were discussed qualitatively, on their geometry relative to river channel dimensions, and on take-in process by peak flows, respectively. An experimental facility was designed to investigate the mechanism of this flood damage, while an optical triangulation system with a laser electronic theodolite of motor-driven was newly developed for the measurement of the experiments. |
