• Wave fetch

• Maximum fetch


  The maximum distance the wind may blow without being interrupted by land
• Formation of waves


  Resultant of the wind strength, the wind blows for, the distance wind has blown
• Constructive waves


  -long wave length

  -small wave height

  -larger swash

  -smaller backwash
• Destructive waves


  -high frequency waves

  -large wave height

  -smaller swash

  -larger backwash
• Wave refraction


  Slowing and bending of progressive waves in shallow water.
• Aeolian


  Moved by the wind
• Fluvial


  Moved by water
• Biotic
