What is the thalweg?

The highest point of a floodplain
The area most protected from flood flows
The boundary of a watershed
The bottom of the river channel most impacted by flood flows

The correct answer is: The bottom of the river channel most impacted by flood flows

The thalweg is the lowest point of a river channel, often described as the "line of greatest descent" or where the water flows the fastest. Option A is incorrect because the highest point of a floodplain would not be in the river channel. Option B is incorrect because the thalweg is not necessarily the most protected area, as it can be subject to greater force from flood flows. Option C is incorrect because although the thalweg may follow the boundary of a watershed, it is not defined as such. Therefore, D is the only correct option.
