Which mechanism allowed ancient Mesopotamian tiered ziggurats to mitigate water damage from seasonal irrigation flooding?

💡 Explanation

When seasonal floods occurred around Mesopotamian ziggurats, dissipation via graded drainage occurred because the stepped structure allowed flood water to gradually drain away from the foundations, preventing water accumulation. Therefore, water dissipation results, rather than wicking, damping, or evaporation, which would require other materials properties and structural features.
