In order to study the effect of arrangement of non-submerged rigid vegetation on surface flow hydraulic characteristics, this paper established a hydraulic model based on the actual situation. The average vegetation was evenly arranged as the control group, the vegetation was arranged in a strip pattern and the distance between the strips increased in multiples of 1.333, 1.667, 2.000, 2.333, 2.667, while the distance within the strips decreased by 0.833, 0.667, 0.500, 0.333, 0.167 as the experimental group. The numerical simulation based on Fluent verified the effects of changes in the arrangement of vegetation with the 5% coverage (210 plants) on the water flow and hydraulic characteristics. The results show that the vegetation coverage was the same and the vegetation arrangement tended to be uniform. Under the influence of water depth, the flow rate decreased, and the Reynolds stress in the lower half of the water depth increased. The surface flow rate on the non-submerged vegetation decreased, and the turbulent flow increased. The water energy is consumed to prevent water and reduce the erosion of water surface. This study provides reference for flood control and disaster reduction.

为研究刚性非淹没植被排列方式对地表水流的影响,结合实际建立水力学模型,以植被间距均匀排列为对照组,植被条带式排列且条带间距以1.333、1.667、2.000、2.333、2.667倍数增大、条带内距离以0.833、0.667、0.500、0.333、0.167倍数减小为试验组,基于Fluent数值模拟5%植被盖度(210株)植被排列方式变化对水流流态和水力特性的影响。结果表明,植被相同盖度,排列趋于均匀:水深影响下,流速减小,水深下半段雷诺应力增大;非淹没植被上表面流速减小,紊流动能增大。消耗了水体能量达到阻水作用并减少了水流表面的冲刷。该研究为防洪减灾提供了参考。

为研究刚性非淹没植被排列方式对地表水流的影响,结合实际建立水力学模型,以植被间距均匀排列为对照组,植被条带式排列且条带间距以1.333、1.667、2.000、2.333、2.667倍数增大、条带内距离以0.833、0.667、0.500、0.333、0.167倍数减小为试验组,基于Fluent数值模拟5%植被盖度(210株)植被排列方式变化对水流流态和水力特性的影响。结果表明,植被相同盖度,排列趋于均匀:水深影响下,流速减小,水深下半段雷诺应力增大;非淹没植被上表面流速减小,紊流动能增大。消耗了水体能量达到阻水作用并减少了水流表面的冲刷。该研究为防洪减灾提供了参考。

In order to study the effect of arrangement of non-submerged rigid vegetation on surface flow hydraulic characteristics, this paper established a hydraulic model based on the actual situation. The average vegetation was evenly arranged as the control group, the vegetation was arranged in a strip pattern and the distance between the strips increased in multiples of 1.333, 1.667, 2.000, 2.333, 2.667, while the distance within the strips decreased by 0.833, 0.667, 0.500, 0.333, 0.167 as the experimental group. The numerical simulation based on Fluent verified the effects of changes in the arrangement of vegetation with the 5% coverage (210 plants) on the water flow and hydraulic characteristics. The results show that the vegetation coverage was the same and the vegetation arrangement tended to be uniform. Under the influence of water depth, the flow rate decreased, and the Reynolds stress in the lower half of the water depth increased. The surface flow rate on the non-submerged vegetation decreased, and the turbulent flow increased. The water energy is consumed to prevent water and reduce the erosion of water surface. This study provides reference for flood control and disaster reduction.
