Which outcome is most likely accompanying increased lahar flows down stratovolcano flanks?

💡 Explanation

Downslope lahar flows, a type of debris flow, will bury valleys because of sediment transport and deposition overwhelming existing channels. Lahar deposition causes destruction, therefore it negatively affects engineering and the environment, rather than enabling soil enrichment.
