Coastal erosion and coastal flooding range are among the most severe concerns of coastal communities. In the future, sea-level rise (SLR) increases the risk of loss of land, assets, and lives. The resilience of coastal systems to SLR, to a large extent, is controlled by coastal sediment availability, being heavily impacted by climate change and anthropogenic modifications in the river catchments. Lincoln Centre for Water and Planetary Health integrates riverine and coastal research to unravel the interactions and feedback mechanisms between “coasts and catchments” to better understand the resilience of natural and social coastal systems.
Sediment delivery in river catchments is reduced by an increasing number of river dams for water supply and energy production. Meanwhile, ongoing land use changes (e.g. deforestation) may increase riverine sediment delivery into the coastal zone.
Where sufficient sediment is available, coastal ecosystems may establish and facilitate land building and land raising through vertical sediment accretion.
Deltas and Estuaries
Marine and riverine forces shape the morphology of river mouth systems, such as deltas and estuaries. Deltas and estuaries are global population hotspots at risk from riverine, coastal and compound flooding events as well as coastal erosion.
Coastal ecosystems are increasingly acknowledged as natural coastal defences, which are ecologically valuable and self-adapting to sea-level rise.
