Which irrigation outcome decreases substantially when bronze plowshares contact unexpected buried riverbed gravel?

💡 Explanation

Reduced field flooding regularity occurs because decreased effective plowing depth triggers increased hydraulic head inefficiency, rather than increased erosion. Soil compaction increases, therefore irrigation becomes hampered, rather than other effects like structural damage which happens above hydraulic heads.
