Overwash Deposition Increases Backbarrier Marsh Resiliency to Sea Level Rise: Insights from a Coupled Barrier Island-marsh Model

Salt Marsh Accretion and Storm Tide Variation: an Example from a Barrier Island in the North Sea

We reconstruct past accretion rates of a salt marsh on the island of Sylt, Germany, using measurements of the radioisotopes Pb and Cs, as well as historical aerial photographs. Results from three cores indicate accretion rates varying between 1 and 16 mm year. Comparisons with tide gauge data show that high accretion rates during the 1980s and 1990s coincide with periods of increased storm acti...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Negative effects of sediment deposition on grazing activity and survival of the limpet Patella vulgata

Sediments are likely to influence the distribution of limpets and dominant sessile species on intertidal rocky shores by smothering and interfering with feeding activity. This hypothesis was tested by field observations and laboratory experiments in which the effects of different amounts and grain sizes of sediments on the grazing and survival of the limpet Patella vulgata L. were measured. On ...
