Abstract
In order to study the influence of aquatic vegetation characteristics on hydraulic characteristics in channels,channel model experiments were designed and conducted to explore the changes in channel water level and flow velocity under the influence of factors such as vegetation growth spacing and inflow flow rate.Experiments have shown that the flow rate into the canal has a relatively small impact on the water level changes in the cross-section of the canal,but the vegetation spacing will change the water level changes in the cross-section of the canal.There are different water level change trends in the intervals of 10～15,20～30 and 35～40mm,respectively.The larger the inflow into the canal,the higher the water level,but the larger the spacing between vegetation growth,the smaller the water level in the canal.When the spacing between vegetation growth does not exceed 25 mm,the flow velocity changes in the channel have an increasing and decreasing stage,while the flow velocity is relatively stable at a spacing of 30～40 mm;The larger the spacing between vegetation growth,the higher the flow velocity.Research suggests that the distribution density and spacing of aquatic vegetation in the canal should be controlled to reduce the impact of aquatic vegetation on the dynamic water potential energy in the canal.关键词
