Which control challenge resulted when seasonal rainfall variability impacted ancient Mesopotamian canals?

💡 Explanation

When seasonal rainfall varied significantly, fluctuating water tables in the canals caused sustained waterlogging of soils, promoting capillary transport and evaporation of groundwater salts, leading to increased salinization. Therefore soil salinization resulted, rather than the alternatives which relate to different processes such as sediment transport, structural fatigue, or nutrient enrichment.
