Abstract: Presently, the natural flow of sediment in rivers and irrigation canals is being impeded by the presence of artificial reservoirs, leading to sediment accumulation. This sedimentation issue is particularly critical for ecologically sensitive coastal regions, such as deltas and polders, which are under threat. This study is carried out in the Ebro River and its delta, a protected natural park in danger of disappearance because numerous areas are below sea level. This situation, exacerbated by the effects of climate change and the water scarcity, poses critical challenges for the preservation of the ecosystem and biodiversity in the region. In the context of the European project IMPETUS, this research aims to develop a model based on Computational Fluid Dynamics (CFD) equations to aid in decision-making processes that focus on preserving sediment levels within rivers. This preservation is of utmost importance, as these regions are increasingly vulnerable to the effects of rising sea levels, a clear manifestation of the impacts of climate change that demands urgent action to develop effective adaptation and mitigation measures. By taking these measures, it seeks to reduce the environmental repercussions of their deterioration resulting from anthropogenic interference and accentuated by climate change.
