Which structural issue historically affected timber canal aqueducts as water permeated the wood?

💡 Explanation

When water permeates the timber, fungal degradation occurs because moisture facilitates fungal growth, weakening the wood's cellular structure. Therefore wall deflection results, rather than collapse, joint failure, or arch buckling which require different loading or environmental conditions.
