Introduction:

Delta is a discrete shoreline protrusion formed at a point where a river enters an ocean or other body of water. It appears like the fourth letter of the Greek alphabet Δ and hence named after it.
Barrier Island is the elongated body of accumulated sand-size particles parallel to the shore, and these deposits are formed by wave action. Barrier island separates the lagoon from the ocean, and lagoon separates land and barrier island.
