← HistoryWhich material migration resulted from ancient Mesopotamian canal construction?
A)Increased downstream topsoil salinity✓
B)Decreased floodplain sediment deposition
C)Elevated groundwater arsenic levels
D)Diminished windblown dust fertilizer
💡 Explanation
Canals promote shallow water tables, causing increased evapotranspiration and capillary action; therefore, increasing downstream topsoil salinity via salt accumulation is the outcome. This occurs because of groundwater movement, rather than sediment/dust changes.
