The Gascoyne River in Western Australia provides nice example of the importance of lobe-switiching / avulsion in the construction of some delta complexes. In this image (top of upper two images is West), it is possible to discern at least 3 lobes. Go explore and find up to 6 (more?). Go upstream and see some spectacular aeolian v. river vignettes that show abandoned fluvial tracts overrun by dunes and one lobe that went astray and may not have met the sea...

Wow! I love this place.

Must.see.this.
