Research paper thumbnail of Modélisation et Optimisation des Inondations en Milieu Urbain avec une Approche Multicritères

Afin de faire face a ce risque, differents acteurs se reunissent dans le but de proposer une solution d’amenagement du territoire, capable de le maitriser au mieux. La solution proposee doit repondre a plusieurs objectifs de natures differentes (economiques, sociaux, politiques,…) qui sont le plus souvent contradictoires. Des outils numeriques d’aide a la decision sont actuellement disponibles et frequemment utilises par les amenageurs pour les aider dans leurs choix d’une solution adequate. Cependant ces outils se basent generalement sur des approches empiriques et l’efficacite des solutions proposees reste incertaine. Dans ce contexte, l’objectif des travaux realises au cours de cette these, consiste a developper une approche complementaire aux outils d’aide a la decision en se basant principalement sur des methodes numeriques directes, telles que la modelisation 3D, la simulation numerique et l’optimisation multicriteres. L’approche consiste dans un premier temps a coupler la modelisation geometrique 3D issue de Systeme d’Information Geographique « SIG » avec la modelisation en mecanique des fluides « CFD », afin de representer le phenomene d’inondation urbaine avec une precision proche du reel. Cette etape permet de fournir une cartographie tridimensionnelle de differentes caracteristiques de l’inondation (Vitesses, Hauteur d’eau, etendue de l’inondation, …), et par consequent localiser les differentes parties de la ville a amenager en priorite. Dans un second temps, en se basant sur les resultats obtenus dans la premiere partie, des strategies d'optimisation multicriteres sont mises en œuvre afin de trouver parmi une multitude de solutions proposees, representant des projets d’amenagement, celle la plus convenable pour la situation etudiee, et qui satisfasse simultanement les differentes contraintes techniques, economiques et environnementales. Une telle approche permet aux decideurs a la fois d’accelerer leur procedure d’analyse du risque dans la zone urbaine et de les rassurer sur l’efficacite de la solution choisie face a ce risque.

This work aims to minimize the flooding damage by optimally design the building location and interspace. The velocity, water pressure and the height of water are considered as the main factors to reduce the flooding damage. The multi-objective optimization is implemented by combing several techniques, including Design of Experiment (DOE), Response Surface Method (RSM) and the Genetic Algorithm (GA). The proposed methodology is validated with a case study on the topography of ESTP Cachan.

In our case the whole available data of the territory - including new and existing buildings and infrastructure - of the National Interest Operation of Paris La Defense (which is France’s largest business district) has been collected and formatted into several databases. Our achieved interoperable BIM model has been adapted to perform complex multi-physical studies and simulations in several technical fields (including noise exposure, wind comfort, artificial and natural lighting, energy consumption, environmental impacts and global comfort) in order to understand and assess the quality of use of public spaces.
