Physical characteristics of a tide-dominated delta

  1. Tide-dominated deltas are characterised by relatively high tide energy at the mouth compared with wave energy, and are distinguished from tide-dominated estuaries by high river energy.
  2. Tidal energy is greatest slightly landward of the mouth due to constriction by the funnel shaped mouth.
  3. Wave energy is dissipated on shoals seaward of the mouth, and declines rapidly landwards.
  4. River energy remains moderate to high along the channel, but drops off significantly as the channel widens towards the mouth.
