On the Use of Global Flood Forecasts and Satellite-Derived Inundation Maps for Flood Monitoring in Data-Sparse Regions
Early flood warning and real-time monitoring systems play a key role in flood risk reduction and disaster response decisions. Global-scale flood forecasting and satellite-based flood detection systems are currently operating, however their reliability for decision making applications needs to be assessed. In this study, we performed comparative evaluations of several operational global flood fo...
متن کاملEvacuation Planning with Flood Inundation as Inputs
Recent flooding events happening in our city demonstrate frequency and severity of floods in the UK, highlighting the need to plan and prepare, and efficiently defend. Different from the numerous evacuation model and optimization algorithms, this paper aims to address flood evacuation planning with flood inundation as inputs. A dynamic flooding model and prediction to estimate the development o...
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 ...
