A cloud-web platform for quickly mapping fluvial flood hazard and risk over large areas

“Large-scale and high resolution geographical/topographical data has the potential to improve resilience in natural and flood hazards. GECOsistema is developing algorithms and technology to realize this potential.”

Recently published paper  Tavares et al. “A web application for hydrogeomorphic flood hazard mapping, Environmental Modelling and Software” (2019), doi: https://doi.org/10.1016/j.envsoft.2019.04.010.

SmartFLOOD is an innovative Cloud-Web platform developed to drastically reduce cost in mapping Fluvial Flood Hazard and Risk at large-scales anywhere in the world.

SmartFLOOD consists in an advanced cloud-web platform for retrieving in real-time detailed, high resolution (less then 30 m) and comprehensive flood risk map of the entire planet.

Integrating large scale and high resolution open data and emerging information and communication technologies in flood risk management for robust, evidence-based decision-making.

SmartFLOOD meets increasingly demanding and challenging needs of risk management policies, providing authorities and stakeholders an innovative solution to assess flood risk.

SmartFLOOD provides quickly to our clients (such as public authorities, in particular civil protection agencies, insurance and re-insurance companies, critical infrastructure, but also citizens) detailed information about areas and assets prone to flooding that supports decision-making and the design measures and the defining of risk transfer schemes (insurance).

Calibrating the GFI for a specific area of interest over an available flood hazard reference map, provided by existing studies or numerical hydrodynamic simulations, the SmarFLOOD platform delivers an higher resolution (downscaling) and an extrapolation (from a sub-basing to the entire hydrological basin)  of the flood hazard reference maps than can be used in more accurate flood risk assessment studies.

The Web Service is designed to provides end-users with the possibility to consistently and cost-effectively extend local detailed flood studies (i.e. those coming from complex flood models, field studies or remote sensing detection) in uncovered data-scarce regions, to extrapolate them to larger scales and downscale to finer resolutions.

The service is fully operative and actually covers the entire PAN-EU and  will be extended soon  to be operative worldwide, it implements the Geomorphic Flood Index (GFI; Samela et al., 2017) workflow described in Tavares da Costa et al. (2017) and developed under the System-Risk project (www.system-risk.eu).

SMARTFLOOD provides to Insurance and reinsurance companies detailed information about areas and assets prone for defining of flood risk transfer schemes.

SMARTFLOOD covers the needs of Public Authorities seeking for a comprehensive, cost effective and homogeneous mapping of large areas to meet the EU Water Framework Directive requirements.

SMARTFLOOD attends to the needs of single users seeking for local high detailed maps in data scarce regions where numerical modeling may not be feasible.

SMARTFLOOD core algorithm is based on the morphological descriptor Geomorphic Flood Index (Samela et al., 2017), GFI, and its use as a linear binary classification feature (Degiorgis et al., 2012).
The workflow starts with terrain analysis (i.e. determination of flow direction, local slope and upslope contributing area) of a Digital Elevation Model (DEM), using TauDEM tools, and the segmentation of a reference map of maximum flood depths using a pre-defined cut-off depth (in this case 0.01 m).
The morphological characterization stage corresponds to the computation of the GFI from terrain analysis layers and the definition of a classification area, used to avoid some classification shortcomings.
The supervised classification of the GFI is then performed within the classification area established for each river basin, searching for the optimal threshold that better represents the binarized reference flood extents. The optimal threshold is subsequently used to segment the GFI layer, resulting in an index-based flood extent map (i.e., all values above or equal to the threshold are flagged as flooded and below as not flooded), or map of flood-prone areas.

Finally, we quantify how well suited the continuous classifier is and how well the classification performed within each, and across, river basins.
