Flood Monitoring from SAR Data

چکیده
Abstract This paper presents the intelligent techniques approach for flood monitoring using Synthetic Aperture Radar (SAR) satellite images. We applied artificial neural networks and Self-Organizing Kohonen Maps (SOMs), to SAR image segmentation and classification. Our approach was used to process data from different SAR satellite instruments (ERS-2/SAR, ENVISAT/ASAR, RADARSAT-1/2) for different flood events: Tisza River, Ukraine and Hungary in 2001; Huaihe River, China in 2007; Mekong River, Thailand and Laos in 2008; Koshi River, India and Nepal in 2008; Norman River, Australia in 2009; Lake Liambezi, Namibia in 2009; Mekong River, Laos in 2009. This approach was implemented using Sensor Web paradigm for integrated system for flood monitoring and management.

Intelligent Computations for Flood Monitoring
Floods represent the most devastating natural hazards in the world, affecting more people and causing more property damage than any other natural phenomena. One of the important problems associated with flood monitoring is flood extent extraction from satellite imagery, since it is impractical to acquire the flood area through field observations. This paper presents a method to flood extent ext...
متن کاملErs-2, Radarsat Sar Backscattering Characteristics of the Parana River Delta Wetland, Argentina
The Lower Delta Islands of the Paraná River in Argentina constitute a major coastal tidal freshwater wetland located at the De La Plata River estuary, very close to Buenos Aires City. It is a complex region where the landscape pattern is characterized by mosaics of natural and man made ecosystems. Since the last few years an increased number of SAR images have been available for monitoring coas...
متن کاملA Multi-Scale Flood Monitoring System Based on Fully Automatic MODIS and TerraSAR-X Processing Chains
A two-component fully automated flood monitoring system is described and evaluated. This is a result of combining two individual flood services that are currently under development at DLR’s (German Aerospace Center) Center for Satellite based Crisis Information (ZKI) to rapidly support disaster management activities. A first-phase monitoring component of the system systematically detects potent...
متن کاملInundation monitoring through high-resolution SAR/InSAR data and 2D hydraulic simulations
In the present paper, COSMO-SkyMed high-resolution data acquired on the southern Basilicata region (Italy) are used for flood hazard monitoring. We concentrate on the flood event of Nov. 2-4, 2010, for which multi-temporal SAR data were available over the Bradano River downstream area in the same acquisition geometry, which allows interferometric processing. SAR intensity data analysis of two a...
متن کاملFlood monitoring in the Senegal River valley: First results based on SAR PRI data
This study focuses on the use of Synthetic Aperture Radar (SAR) data for mapping the extent of flooding events. A small test area in the middle Senegal River valley in the western part of Sahel is studied. Four ERS2 SAR PRI scenes have been used in the analysis for delineation of flooded areas. Change images have been produced by using the latest non-flood image (August 1999) as reference and d...
