Fig. 1. Delta morphology classification. (A) Delta ternary diagram based on dominant processes (Galloway, 1975). Red dots
indicate modern deltas that are analysed further below. (B) Variation of the delta processes during the last 7 ka for selected
Holocene deltas. Note that process changes happen under steady external forcing conditions.
