Measurement of Sedimentation or Accretion Rates

Many methods have been used to measure accretion and sedimentation in wetlands. Each method gives a result relative to a different time period. Most measurements use some variation of a marker horizon or radiometric dating. The time period over which the rates are measured varies from a few
