The new, systematic Global Flood Monitoring (GFM) product of the Copernicus Emergency Management Service will provide a continuous monitoring floods worldwide by immediately processing and analysing all incoming S-1 Interferometric Wide Swath data making use cube approach enabling high timeliness implementation flood mapping algorithms that require data-driven model training. It integrates three independently developed to improve robustness accuracy water extent maps build degree redundancy...
<p>The Global Flood Monitoring (GFM) system of the Copernicus Emergency Management Service (CEMS) addresses challenges and impacts that are caused by flooding. The GFM provides global, near-real time flood extent masks for each newly acquired Sentinel-1 Interferometric Wide Swath Synthetic Aperture Radar (SAR) image, as well information from whole archive 2015 on. is an ensemble product based on a combination three independently developed mapping algorithms individually derive data....
Flood extent maps derived from Synthetic Aperture Radar (SAR) data can communicate spatially-explicit information in a timely and cost-effective manner to support disaster management. Automated processing chains for SAR-based flood mapping have the potential substantially reduce critical time delay between delivery of post-event satellite subsequent provision crisis emergency management authorities. However, accuracy vary drastically due prevalent land cover topography given scene. While...

Sensitivity analysis (SA) describes how varying inputs to a model subsequently varies its outputs. Its inclusion can support the systematic calibration of numerical models back-calculate intensity properties past torrent events that would otherwise be difficult or impossible collect during their occurrence. for is assessed with back-calculation known event. In particular, FLO-2D, cell-based model, used simulate 2005 debris flow event occurred in Brienz, Switzerland. Under 4000 simulations...
Knowledge about the cause of differential structural damages following occurrence hazardous hydro-meteorological events can inform more effective risk management and spatial planning solutions. While studies have been previously conducted to describe relationships between physical vulnerability features building properties, immediate environment event intensity proxies, several key challenges remain. In particular, observations, especially those associated with high magnitude events,...
