摘要：Instream vegetation not only affects the discharge capacity of the river but also plays an important rolein the pollutants diffusion. So it is very important to study the pollutants diffusion in the open channelswith vegetation. In order to experimentally investigate the effects of rigid vegetation on the characteristicsof flow, the vegetation was modelled by a rigid cylindrical rod. The flow field is measured under theconditions of submerged rigid rod in a flume with single layer and double layer vegetation. Experimentswere performed for various spacing of the rigid rods. The vegetation models were aligned with theapproaching flow in a rectangular channel. Vertical distribution of pollutants was evaluated usingimage processing methods. The results indicate that the vegetation has a more stable effect on thespread of pollutants..
