Which problem increased sediment accumulation inside Roman gravity-fed aqueducts, reducing flow?

💡 Explanation

When water velocities increased beyond design thresholds, turbulent flow developed, because higher Reynolds number regimes prevented suspended solids from settling. Therefore, enhanced sediment accumulation occurred rather than deposition, oxidation or biofilm which are independent mechanisms or require specific chemical conditions.
