narrow and low and exist under low-energy conditions or they can be directly exposed to swell waves propagating into the estuary, in which case they might resemble a beach on the open coast, but still be controlled by different processes. They can occur in all tidal conditions, from micro- to macro-tides, and under strong river flows to no river flow.

beach is not clear, in some cases the sand can be lost to tidal channels or stored in the flood-tide delta. In any case, recovery is slow and the sediment transport pathways and mechanisms of recovery are mostly unknown. It has been reported that the recovery of BEBs is slower than the recovery of open-coast beaches.

is the length of water over which a given wind direction blows. This term has been widely used to refer to beaches inside estuaries and bays where locally-generated wind waves are the main source of hydrodynamic energy however, the term can also be applied to beaches outside estuaries and bays, with

BEBs can also exist in estuaries with wide entrances located along wave-dominated coasts such as the SE coast of Australia. Here beaches that are normally subject to low-energy conditions are sometimes exposed to large energy swell that propagates into the estuary/bay during high-energy storms. In

When BEBs are exposed to waves larger than the dominant conditions, they undergo erosion. The volume of erosion can be smaller than the volumes eroded from open-coast beaches, but they might represent a large percentage of the total volume of the beach. The destination of the sand eroded from the

Tide-dominated beaches. This term applies to low-energy high-tide beaches where there is a sharp break in slope, which are fronted with wide intertidal sand and/or mud flats due to the dominance of tidal range over wave height. This term is independent of whether the beaches are located inside an

BEBs can exist in large estuaries with narrow entrances, such as the case of the estuaries of the East coast of the US. In this case, locally-generated wind waves represent the most important physical parameter controlling beach morphology. Given the limitations of basin size, it is typically the

BEBs can be controlled by different types of wave energy depending on their location inside the estuary/bay and the geometric configuration of the estuary/bay. The morphology and characteristics of BEBs vary broadly depending on geology, sediment availability and hydrodynamic energy. They can be

BEBs are often small and isolated and not as iconic as open-ocean beaches in popular culture; and may have a history of litter, pollution and dereliction. However, BEBs are often located around major cities and provide an important recreational and cultural resource. BEBs provide calm swimming

projects such as Operation Posidonia are in place to restore this seagrass. Other coastal protections placed in estuaries, like oyster reefs, are believed to attenuate erosive waves and therefore protect the adjacent BEBs, however, living reefs can create undesired coastal changes related to

BEBs, like all beaches, are accumulations of unconsolidated sediment (i.e., sand) within the cross-shore limits of wave action and occur where there is a suitable supply of sediment and exposure to waves that are energetic enough to move sediment and overcome stabilization by vegetation. The

Other social factors like population and nearby infrastructure control the degree to which a beach is affected by boat wakes and engineering works that can change the geometry of the bay. In fact, most bays and estuaries hosting large cities are strongly modified, for example,
