E-Learning Module: The ECFAS Impact Approach

The ECFAS Impact Tool performs a comprehensive analysis of the impacts generated by coastal inundation by assessing the affected population, the damage to buildings, roads and railways and the exposure of a variety of other assets (e.g. agriculture, points of interest, etc.). The source code (MATLAB 2021b) is provided along with a Windows stand-alone executable. The user can reproduce the impact assessment for the ECFAS test cases, and for user-defined study cases, providing the proper input. The ECFAS Impact Tool is composed of a compressed directory with MATLAB 2021b scripts, a compiled version (Windows 10) of the code and a technical document. All products were implemented under Task 5.3 – Selection and verification of the impact assessment method and represent the Deliverable 5.3 – Algorithms for impact assessment.
