- Abstract:
- The contributions of different types of plant measures and different spatial patterns to efficiency about runoff and sediment reduction are different. In order to investigate effect of hedgerow measure on the engineering accumulation slope of different slope segments of runoff and sediment reduction benefits, the flow rates of 35, 45 and 55 L/min were selected to simulate the rainfall intensity of 0.3, 0.4 and 0.5 mm/min, and the simulation of the 24 degree slope of the accumulation body slope was carried out. The results show that the hedgerow can delay runoff and runoff-yielding time with the flow discharge increase which presents linearly decreasing trend. The average runoff on control slope along the flow direction increased firstly and then decreased, hedgerow slope presents the opposite trend. According to the runoff and sediment yield in different slope sections, the rational allocation of hedgerow measure should focus on strengthening the prevention and control measures for slope of the middle section. The cumulative sediment reduction under 55 L/min flow was much higher than those of the other two flows, the cumulative sediment reduction and time follow the cubic functional relationships. The sediment yield increases along with the increase of the flow rate in the period of time, and the two had a power function relationship. Cumulative sediment yield and cumulative runoff follow quadratic function relationships. The total sediment yield include maximum value, and the function relation is defined. This study can provide theoretical basis for the optimized allocation of control measures on the engineering accumulation body slope.
