Morphology Of Tidal Creek Channels

The coastline of eastern England, between the macro-tidal estuarine systems of the Humber and the Thames is characterised by extensive areas of near sea level marshlands (both natural and reclaimed marsh), freshwater wetlands behind gravel barriers and sand dune-backed beaches, between cliffed sections in often highly erodible pre-glacial and glacial sediments.

Numerous techniques, 1 technologies, 2 and planning measures 3 are available to address the issue of shoreline erosion, with most methods primarily intended to protect property from shore erosion caused by wave attack.

A braided river, or braided channel, consists of a network of river channels separated by small, often temporary, islands called braid bars or, in British usage, aits or eyots.Braided streams occur in rivers with low speed, low slope (but not very low slope), and/or large sediment load. Braided channels are also typical of environments that dramatically decrease channel depth, and consequently.

The Wilson cycle begins with a hypothetical geologically (tectonically) quiet continent.The model is divided into nine stages, but the stages are arbitrary and do not exist naturally.
