Abstract: Many deltaic systems experience river basin regulation, with decreasing solid river discharges and increasing coastal erosion and flooding, that often reach unacceptable thresholds. The Ebro delta (NW Mediterranean Coast, Spain) represents well this sediment starvation problem, resulting in subsidence (up to 5 mm/year) and coastal erosion (up to 40 m/year), associated mainly to river regulation (187 dams) and relative sea-level-rise, RSLR (e. g. Sanchez-Arcilla et al., 2023). There results steadily increasing risks for infrastructures and socioeconomic activities (Sanchez-Arcilla et al., 2022), which can only be sustainably reduced by systemic Nature based Solutions (NbS), illustrated here by restored coastal fluxes to enhance deltaic resilience.
