Which outcome results when flood surges breach levees?

💡 Explanation

Breaching levees cause backwater flooding because hydraulic head reduction reduces river flow inland via hydrostatic pressure; therefore, surge water inundates the protected land rather than river sediments being deposited, which require reduced velocity.
