Which water management outcome occurs during high rainfall on terraced hillsides employing Inca agricultural systems?

💡 Explanation

When rainfall intensity exceeds terrace capacity, water runoff bypasses designed channels because the flow velocity and volume overwhelm interception, leading to progressive topsoil removal, a form of accelerated erosion. Therefore, accelerated erosion results, rather than fertility, drainage, or strengthening, which each depend on intact water flow control.
