| Research Abstract |
The numerical expression of topographies ( distribution of elevation) is important for inundation analysis. Though the expression of topographies with fine grid size has good accuracy, this analysis condition takes more analysis time. In this study, the new inundation analysis method which considered the feature of elevation in grid is developed and the validity and the effectiveness are shown. Moreover, the application of the new inundation analysis method on nesting model and inundation analysis model ( overland flood flow model+sewer model) are developed.
