Data used in "Exploring the Role of Coastal Structures in Shaping Cold-Temperate River-Estuarine Marsh Environments "

This dataset includes orthomosaics and digital surface models (DSM) of the Portneuf and Pointe-Platon marshes, located along the St. Lawrence Fluvial Estuary (Québec, Canada). Surveys were conducted in May using a UAV (WingtraOne Gen1) before the onset of marsh vegetation between 2021 and 2024. It also includes the results of wave data simulated with the GENER model and estimated incident wave power for the 1960–2024 period. For questions, please contact [e-mail].
