Risk Assessment of Field-Scale Flood Disaster Based on Combined Remote Sensing and Hydrological Dynamics Model

Abstract:

There is an increasing need for more accurate information on the hazard and risk of flooding in local region. Besides the national-scale and regional-scale flood risk assessments, it is gradually developed with a focus on particular field-scale conditions in order to ensure that local conditions are taken into account in. On this basis, how to efficiently and effectively make use of the remote sensing monitoring products embedded with hydrological dynamics model is the critical issue for the field-scale flood disaster risk assessment. In this research, based on the established GIS database, it proposed a new combined assessment model, which integrating remote sensing products and SCS hydrological dynamics model to generate the weighted water level of inundated area for assessing the field-scale flood disaster in Hubei province. The major research methods and key technologies involved were discussed briefly. The example result reveals that combined remote sensing and hydrological dynamics field-scale risk assessment model conforms basically to the actual disaster data.
