Tidal delta
In a tidal delta , sedimentation from the water of the flowing river and erosion from the sea from the tidal currents work together.
Features:
- Strong dissection from tidal currents
- Estuary sandbanks are shifted sideways and elongated bars are formed
- Sediments are mostly shifted parallel to the coast
- Widening of at least some estuaries to form estuaries
Examples
- Tidal range in Ponta do Céu: 0.4 - 4.6 m (max.)
- Tidal range in Calcutta : 1.34 - 3.46 m, max. 5.91 m
- Western part of the Rhine-Maas-Scheldt Delta ,
- Tidal range of neighboring ports:
