Which process causes increased soil horizon mixing during flood events?

💡 Explanation

Increased stream discharge induces intense bioturbation, where burrowing organisms like worms mix sediments, therefore the soil horizons become less defined, rather than remaining stable like in normal pedogenesis alone.
