Living Shoreline Permitting Made Easier

The state of North Carolina is well on its way to making it easier for property owners to build living shorelines.

Series of storms more than 150 years ago caused extensive erosion of the Carpinteria Salt Marsh

Flooding isn’t new to the Santa Barbara coastline. However, the inundation doesn’t always come from the mountains as it did last month in Montecito. Back in 1861-2, a series of large storms washed beach sand more than a quarter mile inland into what today is the Carpinteria Salt Marsh. Although historical accounts document the inland flooding, little has been known about how those storms impacted a now heavily developed California coast.

Sea level rise threatens to wipe out West Coast wetlands

Rising seas will drown most wetlands on the U.S. West Coast in less than a century, a new study led by the U.S. Geological Survey warns. In many areas, the wetlands won’t be able to migrate inland without help.

Pacific coast marshes more resistant to rising seas than Atlantic

Pacific marshes are generally at higher elevations than Atlantic marshes, and Pacific oceanographic circulation tends to push water away from the coast, reducing the effect of sea level rise.

New study shows rapid marsh bank sediment build up does not equate land loss resilience

A new study proposes a new framework to look at sediment fluxes in marsh channels that takes into account the natural process of sediment recycling. Understanding how sediments are transported within salt marshes is critical to predict the effect that processes such as nutrient loading, sea-level rise and sediment supply have on marsh erosion.

More than a Billion People Depend on Wetlands

It is estimated that more than a billion people around the world make their living directly from wetlands. And yet some 64 per cent of the world’s wetlands have disappeared since 1900; many of them converted for agricultural use or urban development. Approximately 40 per cent have been degraded in just over 40 years

Normal weather drives salt marsh erosion

Waves from moderate storms, rather than violent events such as hurricanes, inflict the most loss on coastal wetlands. Globally, salt marshes are being lost to waves, changes in land use, higher sea levels, loss of sediment from upstream dams and other factors.

Coastal marshes more resilient to sea-level rise than previously believed

Rising seas threaten coastal marshes worldwide. But a new Duke University study finds marshes are more resilient than previously believed.

The extensive estuarine saltwater marshes of eastern North America are large, flat, grassy areas that are flooded daily by the semidiurnal tides of the Atlantic Ocean.
