CONSTRUCTION WAVES - small low energy waves that deposit sand onto beaches
CORRASION - occurs when waves crash over rock shelves and move rock and other material helping to erode the rock shelf away
CORROSION - the action of salt and minerals like iron that are contained in rock, weakening the rock and making it more susceptable to erosion
DEPOSITION- the depositing of sand and rock particles caused by wind and wave action forming features such as beaches
DESTRUCTIVE WAVES - large waves formed by tropical cyclones and storms that erode material from beaches
EROSION- the removal of rock and sand particles as a result of wind and wave action
FETCH - the distance the wind travels over the ocean to form waves
FOREDUNE - the closest dune to the ocean or the first dune in a sand dune system
HYDRAULIC ACTION - where waves enter cracks in rocks. air is compressed by the force of the water causing erosion and forming features such as blow holes
LONGSHORE DRIFT - the process, caused by waves hitting the coast at an angle, that is responsibe for moving sand along the coast
REFRACTION - the bending of waves around headlands into bays
SURF AND SWASH ZONE - the active part of the coast in terms of erosion and deposition of sand by wave action; the surf zone is immediately adjacent to the coast and the swash zone is at the shore once the waves have broken
VEGETATION SUCCESSION - the natural progression of vegetation from low-lying, salt tolerant plants on the foredune, through to shrubs and established trees on the hind dunes
WAVE HEIGHT - the verticle distance between the trough and the peak of the wave
WAVELENGTH - the horizontal distance between wave peaks
BREAKWATERS - a barrier that breaks the force of wavebefore it enters a harbour or bay
FAECIAL COLIFORM - Aerobic Bacteria Found in the Colon or Faeces, often used as indicators of faecal contamination of water supplies
SILTING - the filling up or raising of the bed of a body of water by depositing silt.TIDAL FLUSHING -
GROUND SWELL - the ground swell is the swell out in the ocean created by the wind
PLUNGING WAVES - break on beaches where the slope is moderately steep. board riders like these waves because of the tubes they form
SPILLING WAVES - break far from the shore on beaches with gentle slopes. the surf gently rolls over the front so these waves are good for body surfing
SURGING WAVES - occur on very steep beaches. the waves roll up the steep face rather than breaking over it. they cause erosion
WIND SWELL - if waves travel only a short distance before they hit land they form a wind swell. a wind swell is marked by a short wavelength and high frequency of waves hitting the coast
AEOLIAN - is another word for wind - aelian transportation of sand is the same as wind transportation of sand
SPINIFEX - spinfex is a type of low-lying coastal vegetation found in the foredunes close to a beach
DREGDING - the mass removal of sand from one place - by humans - to another
ACCRETION CYCLE -
GROYNES - constructed along beaches to catch sand and make beaches wider
REVEGETATION - the replanting of regetation along the coastline
SEA WALLS - used to stop erosion of the coastline and protect property. sea walls often replace the foredune. which is an essential part of the beach erosion
ENVIRONMENTAL IMPACT STUDY - the study of various impacts along the coastline that affect the environment
IMPACT ASSESSMENT - an assessment of the impacts that are affecting the coastline and the environment
BITOU BUSH - is a perennial, dense, sprawling shrub that has recently become an extremely invasive coastal weed
MARRAM GRASS - a perennial grass native to sandy shores along the Great Lakes and Atlantic Coast of North America. it is commonly planted as a sand binder to help stabalise sand dunes.NOXIOUS WEED - a noxious weed is a native or non-native plant that is unwanted in a particular area.
ANEMOMETER - An instrument for measuring wind force and velocity.
