Which outcome results as increased sediment load alters braided river morphology transversing an alluvial plain?

💡 Explanation

When sediment load increases, channel avulsion becomes more frequent because increased deposition raises the channel bed, reducing gradient and leading to channel instability. Therefore channel sinuosity decreases as channels straighten and widen, rather than enhanced levee formation or decreased inundation which would involve different hydraulic and sediment transport regimes.
