A channel is stated as having a controlling depth of 38 feet. Which statement is TRUE?
AI Explanation
The correct answer is D) 100% of the channel width is clear to 38 feet.
The controlling depth of a channel refers to the minimum depth throughout the navigable width of the channel. This means that the entire width of the channel has been cleared to at least 38 feet in depth. The other options are incorrect because they do not accurately describe the definition and implications of a controlling depth.
Option A is incorrect because the controlling depth implies that 100% of the channel is cleared to that depth, not just 50%. Option B is incorrect because the controlling depth refers to the minimum depth, not an average or percentage. Option C is incorrect because the controlling depth describes the depth of the channel, not the conformity of the sides.
