Riverbank resilience

Estuarine riverbank erosion is widespread resulting in both direct and indirect impacts to estuarine assets and values. Direct impacts include the loss of riparian and marine vegetation, and the habitat values it provides at the site. Indirect impacts include the mobilised sediment which cumulatively contributes to a degradation of water quality and smothering of key estuarine and marine fish habitats downstream. Those riverbanks with poor vegetation or without properly designed armouring are most vulnerable to flood events and can increase cumulative impacts.
