After prolonged rainfall, which risk specifically increases within Inca dry stone masonry walls?

💡 Explanation

Inca walls lacked mortar which made them weak against water; prolonged rainfall causes hydraulic undermining because increased pore pressure reduces shear strength, therefore the foundation is destabilized, rather than cavitation (no fluid flow) or electrochemical reactions.
