A New Rapid Flood Inundation Model
In this study, we propose a new Rapid Flood Inundation Model (RFIM). The purpose of the RFIM is to generate predictions of water depth and flood extent using less computer resource than required by two-dimensional shallow water equation models (SWEMs). To be useful the RFIM must produce predictions that are comparable with those obtained from SWEMs. The model described here is an improvement on...
متن کاملGIS and Flood Inundation Model-Based
Abstract: This paper presents the methodology and procedure for flood risk assessment using GIS and flood inundation model (FIM) based on the “micro-zonation concept” in which an entire floodplain considered is divided into numerous unit areas (meshes or grids). In this study, Shinkawa-river floodplain around Nagoya City of Aichi Prefecture in Japan an urbanized lowland area, which was greatly ...
متن کاملInundation Extent and Flood Frequency Mapping Using LANDSAT Imagery and Digital Elevation Models
We modeled the extent of inundation around Poyang Lake, China using 13 Landsat images and two digital elevation models (DEMs). Boundaries of the observed inundation extents were (a) labeled with lake-level measurements taken at a representative hydrological station and (b) interpolated to create a Water Line DEM (WL-DEM) that was used to map inundation frequency. A 30 m contour-based DEM produc...
متن کاملSensitivity and uncertainty in flood inundation modelling – concept of an analysis framework
After the extreme flood event of the Elbe in 2002 the definition of flood risk areas by law and their simulation became more important in Germany. This paper describes a concept of an analysis framework to improve the localisation and duration of validity of flood inundation maps. The twodimensional finite difference model TrimR2D is used and linked to a Monte-Carlo routine for parameter sampli...
متن کاملBenchmarking of flood inundation extent using various dynamically linked one and twodimensional approaches
An accurate representation of linking processes between one-dimensional (1-D) and two-dimensional (2-D) models is of particular importance for many floodmodelling projects. This paper provides a comparison of 1-D/2-D linking methods used to simulate a hypothetical embankment failure. Comparisons were made by implementing 1-D/2-D linked models using two different 1-D/ 2-D linking methods, namely...
