Question 1404Navigation General

You are correct, the answer is A) the top or upstream beginning of a bend. The "head of the bend" refers to the upstream or initial point where a river or channel begins to curve or change direction. This is the start or entry point of the bend, as opposed to the downstream or exit point of the bend. The other answer choices are incorrect because they do not accurately describe the specific location being referred to as the "head of the bend." The center line, midpoint, or downstream end of a bend are not considered the "head" of the bend.
