Which consequence to existing building foundations occurs because seasonal alluvial river flooding exceeds designed bank capacity?

💡 Explanation

Increased hydraulic pressure in saturated alluvial deposits causes soil liquefaction because pore spaces increase; therefore buildings may tilt or sink during aftershocks after a heavy rain-induced flood, rather than other decay alone or pipeline exposure.
