Which consequence arose when seasonal Euphrates flooding increased silt deposition into irrigation canal networks of ancient Sumeria?

💡 Explanation

Diminished crop yields downstream occurred because silt deposition caused sedimentation, decreasing conveyance capacity; therefore, less river water reached furthest fields, rather than providing greater hydraulic head or increased water tables closer to flood sources.
