Delta here refers to the sequence of sedimentary deposits formed at the mouth of a river where it enters the sea or a lake. Sediments transported by the river are deposited as result of the reduction in velocity of the water and will build up over time provided that tidal or other currents do remove these sediments. Sedimentation pattens are typically complex, reflecting the various deposition environments – channels, lagoons and levees – that may co-exist in different parts of the delta a given time, and continuous and discrete changes in the location of these environments throughout the evolution of the delta.
