The total sediment yield in the world is estimated to be 13.5 × 10 9 tons/year and about 75% is trapped, retained and stored in the lakes, and reservoirs ( Batuca and Jordaan, 2000). Consequently, the silting process is reducing the storage capacity of the world's reservoirs by about 1%–1.5% per year.

Salt marshes play a key role in attenuating wave energy and promoting sedimentation necessary to potentially adapt to sea level rise. The changes in the soil surface elevation, as a result of spatially and temporally varied sedimentation pattern, affect the hydrodynamics, marsh edge extension and so the sedimentation rate. Little attention has yet been paid …
