Which consequence arises when the rate of irrigation water evaporation drastically exceeds rainfall inputs in ancient Mesopotamian canals?

💡 Explanation

When evaporation exceeds rainfall input, capillary action draws subsurface water, laden with dissolved salts, to the surface where it evaporates, forming saline crusts. This process results in soil salinization, which reduces soil fertility. Therefore, formation of intractable salt crusts leads to reduced yields, not enhanced yields, stability, also not creating drainage improvements.
