Which consequence resulted when Roman aqueduct channels exceeded design capacity downstream?

💡 Explanation

When aqueduct capacity is exceeded, increased water velocity causes accelerated erosion of channel walls because the shear stress from the water flow surpasses the material's resistance. Therefore erosion of channel walls resulted, rather than sedimentation, flow reduction or source pressure change, which would stem from other system malfunctions.
