A river bend characterized by silting A. scouring on concave side B. silting on convex side C. scouring on convex side and on concave side D. scouring on concave side and silting on convex side

The concave side of a river bend is the side that curves inward. The convex side of a river bend is the side that curves outward. The river’s current is stronger on the concave side of the bend, which causes the riverbed to erode. The sediment that is eroded from the concave side is deposited on the convex side of the bend. This process of erosion and deposition is what causes a river bend to become more and more pronounced over time.

Sc scouring is the process of erosion that occurs when the river’s current is strong enough to remove sediment from the riverbed. Silting is the process of deposition that occurs when sediment is deposited on the riverbed.

The other options are incorrect because they do not describe the process of erosion and deposition that occurs on the concave and convex sides of a river bend.
