Description | An inundation inside the levee analytical method that considered the base-flow of the drainage canal was considered for the suburban area where the mountainous district and the field were contained, and the drainage-canal flowed. The base-flow is presumed from the unsteady flow calculation using the water-levels data of the drainage-canal observed at low-water, and applied to an inundation inside the levee model. The analytical method of the present study was applied to inundation inside the levee in Nishisuga region in Tokushima city that had been generated by Typhoon No. 11 in 2014. The following results were achieved. (1)The water-levels in drainage-canal could be reproduced when it was flooded. (2)The runoff-coefficient presumed by the analytical modeling and the runoff-coefficient calculated from material concerning the land-uses were roughly corresponding. (3)The ratio of the base-flow at the flood peak was estimated to be about 50%. The importance of the evaluation of the base-flow was suggested.
