During ancient Mesopotamian irrigation canal construction, which consequence resulted from insufficient compacting of earthen embankments?

💡 Explanation

When earthen embankments aren't compacted adequately, soil liquefaction can occur because saturation reduces shear strength, leading to catastrophic collapse. Therefore, canal bank collapse results, rather than salinity, sedimentation, or algal blooms which require different processes like mineral leaching, flow dynamics, or nutrient enrichment.
