Abstract

The purpose of this study is to determine the best time variables for the application of sediment elevation tables (SET) in high-energy areas. The SET is a reliable ecological method of determining the rates of sedimentation in coastal environments. Typically, the SET is used in low-energy environments such as swamps, marshes, and mangrove forests. Very little methodology exists for the use of SET measurements in a high-energy environment. Because SET measurements may not distinguish elevational changes between subsurface activity or sediment accretion, we complimented them with horizon marker tile measurements. These target surface accretion of sediment and offer a broader spatial range for measurement. We compare temporal variation in sediment dynamics using SET and HM measurements. Monthly time scales are of greater use for studying both variation and accretion/subsidence in high-energy areas while longer time scales may contain gaps in understanding sediment dynamics due to episodic events such as storms.
