    - the east and south-east monsoon are long fetch, the north-west north-east monsoon are medium fetch or even short fetch

    - long fetch > high waves (energy strong = plunging breakers)

    - high waves, short wavelength = destructive wave

    - destructive wave: weak swash + strong backwash > remove material from beach = erosion

    - erosion > sea caves (Po Pin Chau at Sai Kung), geo (Rocky Harbour at the south-east of Sai Kung Peninsula)

    - the short fetch > sheltered area > sediment deposition

    - form spits and bar (Pui O in Lantau Island)

    * But erosional landforms are more than depositional coastal landforms along the coast in the eastern part of Hong Kong.
