• Application of a new discharge estimation method using multipoint water level hydrographs to a flood in the Minochi river

抄録

A new estimation method of discharge hydrograph during floods, which numerically solves the shallow water equations using multipoint water level hydrographs, is applied to a flood in the Minochi river. The physical environmental data of the river is so limited that topographical surveying using GPS, total stations and 3-d terrestrial laser scanning has been carried out along with continuous observation of water levels at several stations. Concurrently a stage-discharge curve in the river reach is produced by 2-d numerical simulations for relatively low and steady flows. The two methods are applied to a flood discharge in 2007 in the river. It is shown that the new discharge estimation method can give discharge hydrograph, whose peak value agrees well with that estimated by the stage-discharge curve.
