Which outcome occurs when rapid snowmelt increases river discharge past the original design height of levees?

💡 Explanation

When increased discharge exceeds levee height, hydrostatic pressure and saturation weaken the levee’s structural integrity promoting erosion and ultimately breaching, leading to inundation of surrounding areas. Therefore levee breaching occurs, rather than aggradation, deposition, or recharge, which counteract flooding or require different geological processes.
