This paper presents Iber+, a new parallel code based on the numerical model Iber for two-dimensional (2D) flood inundation modelling. The new implementation, which is coded in C++ and takes advantage of the parallelization functionalities both on CPUs (central processing units) and GPUs (graphics processing units), was validated using different benchmark cases and compared, in terms of numerical output and computational efficiency, with other well-known hydraulic software packages. Depending on the complexity of the specific test case, the new parallel implementation can achieve speedups up to two orders of magnitude when compared with the standard version. The speedup is especially remarkable for the GPU parallelization that uses Nvidia CUDA (compute unified device architecture). The efficiency is as good as the one provided by some of the most popular hydraulic models. We also present the application of Iber+ to model an extreme flash flood that took place in the Spanish Pyrenees in October 2012. The new implementation was used to simulate 24 h of real time in roughly eight minutes of computing time, while the standard version needed more than 15 h. This huge improvement in computational efficiency opens up the possibility of using the code for real-time forecasting of flood events in early-warning systems, in order to help decision making under hazardous events that need a fast intervention to deploy countermeasures.

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 these floods is of crucial importance to avoid or minimize the hazards associated to them. This task can be accomplished by means of numerical tools as Iber. Iber is a 2-D numerical model, developed by GEAMA (Universidade da Coruña) and Flumen (Universitat Politècnica de Catalunya), that uses the finite volume technique to solve the 2-D Shallow Water Equations in order to obtain the water depth and velocity components of the flow under different scenarios. To assess the capabilities of Iber  a series of test cases have been reproduced 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. The 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.

Abstract: Preserving the cultural heritage of antiquity is one of the most important tasks of the mankind. On this basis, the European Parliament, via the Policy Department Structural and Cohesion Policies, published the study entitled: “Protecting The Cultural Heritage From Natural Disasters”. This study analyses the actions that are being carried out to protect the cultural heritage from floods, earthquakes and other natural phenomena in Europe. In this work the numerical code Iber has been used to design the protection barriers from floods of the Roman Military Camp of “Aquis Querquennis” (69-79 A.C.). This roman camp, inside the Roman Itinerary “Via Nova”, is located in the shore of the “Las Conchas” impoundment in the Northwest of Spain. This camp is subjected to the floods associated to this impoundment of “Las Conchas”. Therefore, and according to the directives of the European Parliament, a series of protecting measures have been analysed using Iber, which is a 2-D numerical code developed by GEAMA (Universidade da Coruña) and Flumen (Universitat Politècnica de Catalunya) that uses the finite volume technique to solve the 2-D Shallow Water Equations.
