Beaches

Beaches form where wave action erodes shorelines creating an intertidal bench of mobile sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment.

Beaches dominate much of Puget Sound’s shoreline. They are characterized by the active transport of sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. by wave action. They can be divided into those associated with coastal bluffs, where the coastline has retreated landward, and those associated with barrier beaches, where sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. has been deposited seaward of the original coastline. Barriers are numerous and include spits, tombolos, cuspate forelands and a variety of other forms. Most Puget Sound beaches (other than the pocket beaches along rocky coasts) exhibit net longshore transport of sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. and the development of discrete littoral drift cells, within which sources and sinks for sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. and a direction of net transport can be defined. (from Shipman 2008)

Beaches are organized into sites based on the extent littoral drift cells. The 2500 miles of Puget Sound shoreline has been divided into 744 distinct littoral cells where the presence of bluff-backed beach indicates the likely presence of sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. input and transport along retreating coastal bluffs (Cereghino et al 2012).

Littoral drift cells are units of beach that include a source of sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment., conveyance of sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. along the shoreline, and a sink for sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment., either at a convergence zonewhere beach sediment flowing in from two directions accumulates, frequently forming barrier beaches where two drift cells merge, or offshore below the depth of wave action. Shipman 2008 differentiates between beach systems with littoral drift, and pocket beaches where sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. is relatively contained.
