Which threat to hydroelectric dams occurs because rapid tephra deposition?

💡 Explanation

When a volcano errupts, rapid tephra deposition can overwhelm intake screens, which then collapse because structural load builds up excessively; therefore, 'intake screen structural overload' is correct, rather than turbine cavitation or generator failures, as it directly addresses structural problems.

• Which consequence results throughout the Mississippi River Valley when glacial outburst floods deposit excess fine loess?
• Which effect is amplified when polar ice melt accelerates oceanic currents?
• Which feedback loop accelerates cirque erosion under increased warming?
• Which climate effect results when the Intertropical Convergence Zone (ITCZ) annual oscillation is restricted to a narrow latitudinal band?
• Which outcome typically occurs when hydraulic sorting decreases drastically upstream of a glacial lake?
• Which disruptive effect arises from upwelling's sudden reduction?
