Which risk increases for early water canals that lacked periodic dredging?

💡 Explanation

Reduced conveyance capacity arises from sedimentation because sediment accumulation obstructs flow, decreasing effective cross-sectional area; this process is deposition, rather than sediment-dispersion; therefore reduced capacity results from sedimentation, rather than other structural damages.
