WebMar 23, 2024 · The key factors which affect coastlines are: The rock type/geology (see map below). The fetch of the wave and the strength of the wind. The angle of the slope – steep slopes erode more violently and frequently. Weather conditions – freezing temperatures and heavy rain increase weathering and the rate of erosion. http://thebritishgeographer.weebly.com/coastal-processes.html
Webbreaks, and rushes up the beach. Movement of water up the beach is called swash. Movement of water down the beach is called backwash (Figure 2b). Sea bed topography can also influence how a wave breaks. A sudden reduction in water depth over a steeper shingle profile will produce a taller, steeper wave which is more likely to plunge. A WebWaves, water level, and sediment grain size are the main controlling factors of beach profile shape. Terminology associated with the beach profile is shown in Figure B40. The backshore runs from the seaward-most dune or the cliff to the land and water intersection.
WebThe low pressure raises the sea level, producing higher tides than normal and the storms add energy to the waves, especially in storms. • The sea floor is deep in the North Sea, meaning waves hit the coast relatively fast and are not slowed down by friction. Longshore Drift and Beach Material • The beaches here are the main problem. WebCross-shore and longshore changes in beach sediment characteristics can result from mechanical and chemical breakdown, differential transport of grains according to their size, longshore variations in wave energy, the addition or loss of sediment, or the mixing of two or more distinct sediment populations.
