Climate change also has effects on the strength of the coastline. As global sea levels rise, the areas within the Mississippi River Delta that experience subsidence may permanently flood and become open water. Additionally, the lack of sediment into these flooded areas also exacerbates the rate at which sea level rise affects the region. [44]
A bore in Morecambe Bay, in the United Kingdom Video of the Arnside Bore, in the United Kingdom The tidal bore in Upper Cook Inlet, in Alaska. A tidal bore, [1] often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay, reversing the direction of the river or bay's current.
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone .
Model of Estuary. The residence time of water is a key variable determining the health of an estuary, particularly from human-induced stresses.Rapid flushing ensures that there is insufficient time for sediment accumulation or dissolved oxygen depletion in the estuary; thus a well flushed estuary is intrinsically more robust than a poorly flushed estuary.

Wave-dominated delta - River energy [3] Manning River (NSW) and Yarra River (Vic) Tide-dominated estuary - Tide energy [ 4 ] a good example is Ord River (WA) and Broad Sound (Queensland) Wave-dominated estuary - Wave energy [ 5 ] - good example Peel Inlet Western Australia and Lake Illawarra NSW.
Tidal salt marsh at Ella Nore in Chichester, England. A tidal marsh (also known as a type of "tidal wetland") is a marsh found along rivers, coasts and estuaries which floods and drains by the tidal movement of the adjacent estuary, sea or ocean. [1]
In Greece, according to the L. 2971/01, the foreshore zone is defined as the area of the coast that might be reached by the maximum climbing of the waves on the coast (maximum wave run-up on the coast) in their maximum capacity (maximum referring to the "usually maximum winter waves" and of course not to exceptional cases, such as tsunamis ...
A tidal creek or tidal channel is a narrow inlet or estuary that is affected by the ebb and flow of ocean tides. [1] Thus, it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils. Tidal creeks are characterized by slow water velocity, resulting in buildup of fine, organic sediment in wetlands.
