The answer is correct.

As the sewers are never designed to flow full (otherwise it'll become a pressure flow case which is generally not provided in case of sewers) and also upper one-fourth portion is always kept vacant in order to avoid mixing of the sewage with the gases (H2S, etc).

Top side is the answer.

On the top side it's corrosion which happen due to gases like h2s and methane.

On bottom side it's scouring due to waste particle present in sewage.
