Sentences with phrase «marsh erosion»

Global salt marsh erosion is largely driven by regular weather patterns, rather than the occasional violent storm.

Analyzing eight salt marsh locations in Australia, Italy and the United States, «we found that the behavior of salt marshes is very predictable,» says Leonardi, with a constant relationship between wave energy and the speed of marsh erosion.

«You can take the geography of a salt marsh and the estuary around it, and if you understand the wind climate and the wave climate, using historical data, you now can predict the marsh erosion,» says Ganju.

This is an example of salt marsh erosion for one of the study sites.

But most of the finer sediment, he believes, spreads far and wide — into the Essex marshes, for instance, and even to the shores of Denmark, the Netherlands and Germany: «Any plan to prevent erosion of Holderness could be seen as a major impediment to the development of some of the valuable coastlines of Europe.»

Salt marshes perform a long list of ecological services: they buffer coastal erosion; filter runoff; reduce the risk of flooding; provide habitat for juvenile fish, crabs and shrimp; and store excess carbon, keeping it from re-entering Earth's atmosphere.

One is geomorphological: erosion provides the sediment that builds up the natural coastal defences of other areas of coastline, by forming marshes or beaches, shingle bars or mud flats.

Dominated by brackish marsh, this area was badly damaged by saltwater intrusion and erosion following the dredging of the MRGO.

Ridge restoration projects can work with hydrologic restoration projects to reestablish historic salinities within the basin, reduce shoreline erosion of marsh creation projects and trap sediment from sediment diversions to help build land more quickly.

Coastal marshes absorb and store large amounts of carbon dioxide from Earth's atmosphere; they help filter out pollution in coastal waters; provide habitat for wildlife; help protect coastlines from erosion and storm surge; and can store huge amounts of floodwater, reducing the threat of flooding in low - lying coastal areas.
