You mean the rivermouth near Pan Harkor?
It's an estuary due to the dominace of tides in this region, like the Thames estuary for example. Growing up near an estuary somehow influenced my map.
It's early 19th century.

No, I meant the river at the far south, flowing north past "Niwt." It splits into two.

The one near Matam splits into three for that matter... I has assumed this was a delta but I just saw the city/town in the middle of it.

[Yoscha]

Those two are deltas.

And I admit, I like to place cities in deltaic enviroments, possibly cause I live in one .

I do something similar Yoscha. I live where 2 real big rivers connect so I always put my cities where rivers join.
