Predicting Flood Inundation and Risk Using Geographic Information System and Hydrodynamic Model
Foreword High flows of water is a common problem in most rivers. Earlier generations were more aware of the risks to build close to the rivers and the highest water level was locally known. Nowadays, building permits are more and more frequent below that level. Furthermore, forestry methods with clear cuts and drainage of wetlands result in a more rapid effect of heavy rain fall on the water fl...
متن کاملA 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 کاملApplication of a 2D Hydrodynamic Model for Assessing Flood Risk from Extreme Storm Events
In the wake of increasing flood disasters, there is an increasing use of flood inundation models to assess risks and impacts at different temporal and spatial scales. Assessing the impacts of extreme climatic rainfall events will require developing design rainfall profiles to represent rainfall under different conditions. Rainfall profiles of different return periods were developed using the Fl...
متن کاملFlood hazard zones using 2d hydrodynamic modeling and remote sensing approaches
Increasing frequency and severity of flooding demands identification of flood hazard zones in Kalilangan, Bukidnon in response to the echoing need of better disaster preparedness via enhancing the understanding and awareness of the public on flood characteristics by integrating the use of two-dimensional hydrodynamic modeling and remote sensing. Flood simulation was carried out in a two-dimensi...
