Summary

A beach–inlet system is composed of several sub-environments, including beach and nearshore, tidal inlet and ebb and flood tidal deltas, and coastal dunes. Building upon Chapter 2, this chapter discusses in detail the sedimentologic characteristics and morphodynamics of the various sub-environments composing a beach–inlet system. Commonly used concepts in quantifying beach morphology and its changes, including equilibrium beach profile, depth of closure, and the Bruun Rule, are reviewed. Coastal dunes and their morphodynamics are discussed in the context of beach–dune interaction. Morphologic and sedimentologic characteristics of tidal inlets and their associated ebb tidal delta and flood tidal delta are described in detail in terms of various morphology features. General patterns of sediment exchange for wave-dominated and mixed-energy beach–inlet systems are introduced.
