Sébastien E. BOURBAN

Directeur Adjoint LHSV

Passionate, driven and genuinely committed in managing and delivering environmental hydraulics research projects with large numerical modelling components. Sébastien has over 25 year experience in Europe (with HR Wallingford from early 1997 till 2001 and between 2008 and 2019) and in North America (with the Canadian Hydraulics Centre between 2001 and 2008). After a short stay at ARTELIA in 2019 as team leader and project director in all aspects of maritime hydraulics, he has now joined the LNHE department at EDF R&D near Paris in 2020.

, 2025 . Urban drainage system failures are becoming more and more common due to the increase in magnitude and frequency of extreme rainfall events and pose significant safety and sanitary risks for urban populations during urban flooding. Practitioners involved in urban planning need comprehensive numerical tools to accurately describe the interplay between flows in the drainage network and floodwaters in the street network during extreme rainfall. EDF R&D, France, and Yuansuan, China, have recently coupled TELEMAC with the stormwater management software SWMM, from the US-EPA, under the git development branch called "swordtail". This branch is available to developers for testing and validation. The coupled system is initially tested against experimental data from a 2×2 street network only (no sewer network), investigated by Mejia-Morales [2021] where numerical parameters are calibrated for the experimental platform, with errors below 3% for flow rates and 5% for flow depths. Building on this calibration, a second case study investigates a surface-todrainage scenario based on experimental observations of a 3×3 street network with 12 drains by Camazzola et al. [2025]. The model is able to reproduce flow rates through the drains, discharge in the main street, and qualitative flow structures such as swirling eddies.
