- 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.
- Tidal energy is greatest slightly landward of the mouth due to constriction by the funnel shaped mouth.
- Wave energy is dissipated on shoals seaward of the mouth, and declines rapidly landwards.
- River energy remains moderate to high along the channel, but drops off significantly as the channel widens towards the mouth.
