Abstract: Urban and industrial water intakes rely on a constant supply of clean water but can be disrupted by the accumulation of aquatic vegetation due to environmental or natural factors (such as floods). The grids installed to block these debris risk becoming clogged, causing pressure losses and affecting the reliability of the water intake structures. In order to understand the dynamics of water flow through porous media composed of aquatic plants, a numerical study is conducted in 2D using the CFD (Computational Fluid Dynamics) software code_saturne developed by EDF R&D. In this study, the porous medium is modeled as a network of solid cylinders, with the aim of producing a profile of the free surface drop in the porous zone. These results are then compared with the ones obtained using the porosity model in code_saturne.
