Which risk increases when hydraulic head pressure diminishes an oxbow's levee?

💡 Explanation

River avulsion increases because decreased levee pressure facilitates channel incision via hydraulic action, eventually cutting through the levee; therefore, the river shifts, rather than continuing the established course.
