RECERCAT author Soler i Ortega, Marianna author Colomer, Jordi author Folkard, Andrew author Serra Putellas, Teresa 2024-10-01 Wetlands produce key ecosystem services to mitigate the impacts of peak flows caused by pluvial or fluvial floods or storm surges. Sediment floods were characterized by a peak flow flowing over a simulated wetland, populated with two natural species. Floods have been drawn as flows of height H, into waters of height h, where H > h. Peak flow along the flume passed through: peak flow adjustment; peak flow; drag-dominated peak flow; and gravity current regimes. For high inundation wetland levels, settling rates of coarse and fine sediment were similar during the peak flow regime. At larger distances, sedimentation decreased monotonically, with higher sedimentation of fine particles. For low inundation levels, the sedimentation rate during the drag-dominated peak flow regime was higher for coarse particles. Vegetation decreased the inundation level needed for enhancing sedimentation. Our study then adds practical knowledge at considering that the synergies between the vegetation and the inundation level may enhance wetland services such as the mitigation of pluvial, fluvial or coastal floodingsThis work was supported by the Ministerio de Ciencia e Innovación of theOpen Access funding provided thanks to the CRUE-CSIC agreement with Elsevier Attribution-NonCommercial 4.0 International http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess Hidrodinàmica Hydrodynamics Sedimentació Sedimentation and deposition Aiguamolls Marshes Inundacions Floods Interactions between vegetation, sedimentation and flood inundation levels in wetlands info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed
