Abstract: Vegetation of various heights commonly co-exists along natural rivers and wetlands, where sediment, ecological environment, and habit biodiversity are drawing increasing attention in the research in ecoenvironment and river restoration. In the past, many researchers studied the impact of vegetation on the flow, such as velocity, flow resistance and Reynolds stresses. Due to the extreme complex of interaction between vegetation and flow, previous studies mainly focus on the unform vegetation through flow in open-channels. However, in natural rivers, vegetation of various heights often co-exists and grows along the river bank. In this regard, it is not yet understood about flow characteristics in such flow conditions, i. e. flow with a mixing array of short and tall vegetation along a channel. This paper is to perform a novel experimental study on a water flume, which is partially covered by a mixed vegetation of different heights along one side of the channel, in order to understand the effect of vegetation on the lateral distribution of velocity and discharge.
