Triangle after gamma (5)

Ross

I believe the answer is:

delta

(Other definitions for delta that I've seen before include "Extended area at river mouth" , "Area of alluvial deposit" , "Silted estuary" , "Triangular patch of land at mouth of river" , "Mouth of, eg, the Nile" .)

I've seen this clue in The Washington Post.
