Which structural weakness was significant in early Mesopotamian canals?

💡 Explanation

Early canals suffered seepage, which is water loss driven by hydrostatic pressure because the unlined earthen construction lacked sealant, therefore reducing irrigation efficiency, rather than the other options which affected established water transport pathways.
