<span>Iber as a tool to analyse flooding scenarios </span>

Abstract

Floods are one of the most dangerous extreme events that can affect people and properties. These events have intensified worldwide over the last decades due to climate change. Therefore, the capability to predict and analyse, in a quick and accurate way, the effects of floods is crucial to avoid or minimize the hazards associated to them. This task can be accomplished by means of numerical tools as Iber, which is a numerical model that uses the finite volume technique to solve the 2-D Shallow Water Equations to obtain water depth and velocity components of the flow under different scenarios. A series of test cases have been reproduced to assess the capabilities of Iber following the document "Benchmarking the latest generation of 2D hydraulic modelling packages" published by the non-departmental public body Environment Agency of the U.K. Government. Results show that Iber is a suitable tool to reproduce accurately different flooding scenarios. A new implementation of the model has been developed by EPHYSLAB. This implementation takes advantage of the modern hardware capabilities and provides significant speedups over the original code. The new possibilities offered by a faster code will be studied.
