coasts

• waves are formed due to an energy transfer and the wind
• wave energy depends on:

  • distance (of wind)
  • speed
  • time
• destructive wave : stronger backwash than swash
• constructive wave : stronger swash than backwash
• destructive waves:

  • stormy conditions
  • high energy
  • far distance travelled (fetch)
  • erosion
• constructive waves:

  • calm conditions
  • lower energy
  • longshore drift
  • deposition
