Which outcome occurs if a section of an ancient Mesopotamian canal collapses due to erosion?

💡 Explanation

When an irrigation canal fails due to a breach, water flow control is lost, because the hydraulic gradient is uncontrolled. This leads to over-saturation and increased evaporation in localized areas, causing increased salinity in the soil. Therefore salinization rises, as opposed to river changes, sedimentation shifts or forced relocation which are determined by larger political, economical drivers.
