Wave Transportation is the types of load moved by waves are such as shingle, sand, mud and other objects dumped into the sea. Waves transport load by a process called long shore drift.
Long shore drift is progressive dragging of materials along the beach as a result of waves breaking at an angle. The factors that influencing wave transportation includes:
1. Strength of waves; Strong waves carry large quantities of load over a long distance while weak waves carry small quantities of load over a short distance.
2. Tides; Tides cause waves to break farther inland causing materials that were not in contact with breaking waves to be moved about.
3. Ocean currents; Ocean currents cause movement of materials from one part of the ocean to another e.g. coconut fruits from southern part of Africa to Gulf of Guinea by Benguela current.
4. Gradient of the shore; On gentle coasts transportation of materials is favoured by long shore drift while on a steep coast they bounce off cliffs and remain floating.
5. Orientation of coast line; Transportation by long shore drift is favoured where coast is aligned obliquely to the direction of breaking waves while on transversely aligned coast swash moves materials back and fourth along the same line.
6. Nature of the load; Lighter materials such as sand are carried over long distances while heavy load is transported over a short distance.
