Advances in research on flows with vegetation in river management

River management covers a wide range including irrigation, flood control, river ecology and environment etc., aiming at protecting and recovering the ecological function of river ecosystem.The vegetation is an important feature of ecological river.It provides the habitat for animals and is a key factor to maintain the healthy development of river.The vegetation changes flow characteristic and sediment and contaminant transport, and thus the flows with vegetation have been wide interested in rivermanagement and become a new important topic in river dynamics.This paper reviews the main research achievements of the flow with vegetation, including four main aspects: flows resistance, turbulence structure, sediment transport and passive scalar dispersion and transport.The main methods, conclusions and measurement techniques are introduced in detail and some limitation of recent research and the research tendencies are also discussed.
