Optimisation of Nature Based Solutions for urban stormwater management, high resolution of radar data and fully distributed modelling: The Bièvre case study
Optimisation des Solutions Fondées sur la Nature pour la gestion des eaux pluviales en milieu urbain, haute résolution des données radar et de la modélisation totalement distribuée : Le cas d'étude de la Bièvre
Résumé
Significant paradigm shifts have occurred in water management, especially with Nature-Based Solutions. This is particularly the case for semi-urban catchments such as the one of the Upper Bièvre Valley. We show how their management can be better assessed, and therefore optimised, by combining high resolution X-band and double-polarised radar data with fully distributed physical-based hydraulic model. Both have the advantage of overcoming the traditional calibration problems that become more and more difficult with the increase of the resolution, and thus offer an easier framework for downscaling.
