Cuspate deltas (e.g. Ebro Delta, Spain) are vaguely shaped like a V with curved sides. Cuspate deltas form when a river flows into a sea with waves that hit it head on, spreading the deposited sediment out. Bird's foot deltas (e.g. The Mississippi Delta) are shaped like (as the name suggests) a bird's foot.
Also asked, what are the 3 types of deltas?
The three main types of deltas are the arcuate, the bird's foot and the cuspate.
Similarly, what is a bird's foot delta?
Definition of bird-foot delta : a delta (such as that of the Mississippi river) having many levee-bordered channels extending seaward like outstretched claws.
There are four main types of deltas classified by the processes that control the build-up of silt: wave-dominated, tide-dominated, Gilbert deltas, and estuarine deltas. In a wave-dominated delta, the movement of waves controls a delta's size and shape.
