Dr. Daniel Caviedes-Voullième
Title: Towards Exascale Physically-based Computational Hydrology
Physically-based hydrological models can be understood as an upscaling exercise of hydrodynamic numerical models. The latter have experienced great development in the past two decades, which together with the accelerated growth of computational power, now enable to tackle catchment and even regional scale hydrological modelling based on such tools. This talk summarizes the ongoing efforts to deploy an open-source, scalable physically-based hydrodynamic solver for catchment scale hydrology and water mediated transport called SERGHEI, demonstrating some key applications concentrated on very highly resolved surface flow hydrodynamics and transport, recent developments with subsurface flow, and highlighting new opportunities and open challenges.
About the speaker:
Daniel Caviedes-Voullieme is a computational hydrologist. He is the team leader of the Simulation and Data Laboratory for Terrestrial Systems of the Jülich Supercomputing Centre (Forschungszentrum Jülich). He obtained a Civil Engineering degree from the University of Costa Rica, an Msc in Applied Mechanics and a PhD degree from the University of Zaragoza. He has previously held research and teaching positions at the University of Zaragoza (ES), University of Sheffield (UK) and BTU Cottbus-Senftenberg (DE). His research is centered around high-performing, performance-portable and scalable numerical solvers for hydrodynamics and hydrology, and their application for hydraulics and hydrology across scales both for natural hazards as well as ecohydrology and landscape function.
