Width of meandering belt is the distance between the apex point of one curve and apex point on the ______.

Concept:

Meander belt width:

The width of the meandering belt is the distance between the apex point of one curve and the apex point on the reverse curve. In other words, meander width refers to the lateral distance between the two outer edges or banks of a meander loop in a river or stream channel.

Meander length:

Meander length refers to the distance along the winding or sinuous path of a river or stream channel between two consecutive meander loops or bends. In other words, it is the length of the river channel as it curves and twists through its course.

Hence option (1) is correct.
