Study of the impact of the Îlot Tison weir on bedload transport of the Clain River (Poitiers, France) using BASEMENT software

Résumé

An increasing number of numerical morphodynamic models predict the evolution of bed configuration over a wide spectrum of spatial and temporal scales due to the development of advanced numerical methods and increased computational power. The increasing use of numerical morphodynamic models is closely related to the growing availability of high-resolution river data sets. Today, the main difficulty in using numerical morphodynamic models is that they are used by nonspecialists modellers or modellers that are not morphodynamics specialists, which can lead to errors. These errors include inadequate parameterization of processes for applications at larger spatial and temporal scales, confusion between physical and numerical phenomena when interpreting numerical results, and the assumption that there is a need for a huge volume of data for developing numerical morphodynamic models. The present work aims to achieve two objectives. To avoid these errors, the first objective is to outline the steps in the development of numerical morphodynamic models. The development of numerical morphodynamic models is now possible with public databases. The second objective is to show the effectiveness of BASEMENT to study the impact of existing and future structures on the river hydrodynamics and bedload transport using case study examples.
