Abstract

The Yellow River Basin is ecologically fragile. The sand production in the Loess Plateau gully erosion accounts for more than 50% of the total sand production in the basin. Plant foliage can reduce the raindrop-scouring force. The root system can reduce the erosion of the soil. In contrast, the willow pile arrangement and combination of the impact of the water flow in the gully energy dissipation and erosion reduction should be studied more. To investigate the effect of different combinations of willow piles on the erosion reduction of the gully. The optimal combination of hexagonal (corner facing upstream A, side facing upstream B) and triangular (C) arrangements for energy dissipation and erosion reduction of willow piles at scouring intensities of 1.8 L·min⁻¹, 2.4 L·min⁻¹, and 3.0 L·min⁻¹ was quantitatively analyzed. The results indicate that the willow pile group has an inhibiting effect on the erosion of the gully. After 20 min scouring of the slope, the gully scour erosion of class A arrangement is the smallest. This arrangement has the most considerable inhibiting effect on the erosion of the gully. The cumulative erosion-reducing effects of the willow pile group of class A, class B, and class C on the average sediment of the gully are 54.2%, 50.0%, and 38.8%. Respectively, erosion reduction benefits: class A > class B > class C. In conclusion, the erosion reduction effect of the Class A arrangement is better than that of other arrangements in this research. This research provides new ideas for the management of gully on the Loess Plateau. To provide technical references for the Yellow River Basin ecological protection and high-content development.
