The Ebro Delta in Catalonia, Spain is an ecologically and commercially important wetland system under threat from sea level rise and marsh subsidence. Our principal hypothesis was that a brackish marsh that receives inorganic sediments and fresh water amendments from the Ebro River would exhibit significantly higher rates of soil accretion, resulting in a greater resistance to subsidence and sea level rise compared to isolated salt marsh habitats with no river subsidy. Marsh sites… Expand

Pristine vs. human-altered Ebro Delta habitats display contrasting resilience to RSLR.
TLDR
Comparing the dynamics of habitat shifts under two departure conditions using the Sea Level Affecting Marshes Model (SLAMM) under the 4.5 and 8.5 RCP scenarios shows promoting preservation of natural habitats by transforming unproductive rice fields into wetlands could be the most sustainable option in the worst RCP scenario.

Tidal wetlands play an important role with respect to climate change because of both their sensitivity to sea-level rise and their ability to sequester carbon dioxide from the atmosphere.Expand
Environmental controls on carbon sequestration, sediment accretion, and elevation change in the Ebro River Delta: Implications for wetland restoration
Abstract Delta wetlands are increasingly recognized as important sinks for ‘blue carbon,’ although this and other ecosystem services that deltas provide are threatened by human activities. WeExpand
Geomorphic influences on the contribution of vegetation to soil C accumulation and accretion in Spartina alterniflora marshes
Abstract. Salt marshes are important hotspots of long-term belowground carbon (C) storage, where plant biomass and allochthonous C can be preserved in the soil for thousands of years. However, CExpand
Soil and phosphorus accretion rates in sub-tropical wetlands: Everglades Stormwater Treatment Areas as a case example.
TLDR
It was showed that soil and P accretion rates leveled off after 10 yr of treatment wetlands' operation, and on comparison, soil Accretion rates and RAS depth determined by CPT were commensurate with that measured by other techniques. Expand

TLDR
A 3D model of tidal marsh accretion and channel network development that couples physical sediment transport processes with vegetation biomass productivity is developed that promotes a metastable equilibrium where the platform maintains elevation relative to a rapidly rising sea level. Expand
