The classification scheme after Galloway (40), where wave-, tide-, and river-dominated deltas are distinguished in the extremes of the triangle. By comparing 16 major river deltas, Wright and Coelman (38) concluded that, in the extremes, the Mississippi River delta is the most river-dominated delta and the São Francisco River delta is the most wave-dominated one. The delta of the Fly River in Papua New Guinea is mainly dominated by the tides.
