Data Fusion for Flood Analysis and Decision Support

Objective

ANFAS project aims at developing a Support Decision System for flood prevention and protection, integrating the most advanced techniques of data processing and management. Tools based on Computer Vision and Scientific Computing will enable to create a model of the scene and to perform flood simulation. Close involvement of end-users and industrial partners may lead to the realisation of an Integrated Information System close to a prototype. Pilot applications will be carried out on the Vah river in Slovaka, the Loire in France, the Poyang lake and the Three Gorges reservoir in China.

Objectives:
The overall objective of the ANFAS project is to develop a Decision Support System for flood prevention and protection, integrating the most advanced techniques in data processing and management. When a flood is going to happen, decision makers have to decide what are the most appropriate reactions: evacuation of the population, reinforcement of dikes, etc. The aim of the ANFAS project is to develop a tool to help decision makers in taking the decision that will limit the flood damage.

Work description:

The ANFAS project will:
- use data from the most advanced acquisition technology;
in particular remote sensing imagery -optical, radar, interferometry radar- will be incorporated into a conventional Geographical Information System database;
- develop advanced data processing tools for Scene modelling and Flood simulation; Computer Vision and Scientific Computing will be used together in order to take into account information extracted from real images for the calculation of parameters for the simulation model;
- have strong end-users involvment through the definition of the objectives, the conception of the System, the evaluation of the simulation results; it ensures that the System answers to "terrain needs" and to be well adapted in practical use;
- involve industrial partners for the realisation of the final System; it is of major importance for the design of the System; one of the main characteristics of the System will be to be modular, i.e. to be composed of blocks easily interchangeable

The functionality of ANFAS System will be:
- to perform flood simulation given a scenario, water flow propagation is simulated; the user can interact with the scene that models the real site in order to add/remove dikes or other human constructions;
- to assess flood damage; flood assessment can be done either using the simulation results or using the remote sensed images of a real flood event;
- at a prospective level, to analyse geological property changes due to repetitive floods for a given site.

The output of the System will be:
- visualisation: it consists of the bidimensional maps of the extent of the flood; if simulation is performed, time sequence maps retracing the propagation of the simulated flood will be provided
- direct impact assessment evaluation of he total affected area; regional and statistical analyses over the affected area; simple socio-economic assessment directly caused by flood.

Milestones:
At the end of the project, three subsystems will be delivered, namely:
Geographic information system database;
tools for Scene modelling from images;
Flood model and simulation;
the final Integrated Information System, which consists of the integration of the three subsystems Semestrial reports and documentations related to the works achievement
