Summary | We developed 2-dimensional river bed variation analysis model incorporating the expansion and extinction of vegetation, the deposits of fine sediment into vegetation area, and the increase of resistance against flood flow by growth of trees. And we tried to apply this model to make an assessment on habitat quality of the Kita-river, and compare some alternatives of river-channel design in term of the balance of improvement of flood flow capacity, river environment conservation, and cost of river-channel management. |
