Read the following statements and identify the correct answers.
I : Athalweg is the line connecting points of maximum depth.
II : Most thalweg pass through a succession of pools in the channel bed that are separated by riffles.
Answer: A
The answer is Both I and II are correct.
The thalweg (German for 'valley way') is the line joining the deepest points along a river channel, so statement I is correct. In most alluvial channels the bed alternates between deep pools and shallow riffles, and the thalweg runs through the succession of pools, crossing from side to side in meandering reaches, so statement II is also correct.
That rules out the options marking either statement, or both, as incorrect.
