Which problem frequently arose in Sumerian irrigation systems due to uncontrolled water flow?

💡 Explanation

When irrigation water evaporates in arid climates, salt accumulates in the topsoil because dissolved minerals are left behind, causing salinization. Therefore arable land becomes infertile, rather than silting, weed growth, or levee collapse, which depend more on sedimentation, nutrient levels, and mechanical stress, respectively.
