From: Deltas: a new classification expanding Bates’s concepts
The three different delta types recognized by Bates (1953) according to the density contrast between the incoming fluid and the receiving water body. a Marine littoral deltas, generated by hypopycnal flows (ρr < ρw). b Lacustrine littoral “Gilbert” deltas, generated by homopycnal flows (ρr = ρw). c Submarine deltas, generated by hyperpycnal flows (ρr > ρw). Modified after Zavala and Pan (2018). ρr = Bulk density of the river discharge. ρw = Density of the water in the reservoir
