Meandering Characteristics of the Yimin River in Hulun Buir Grassland, Inner Mongolia, China

The evolution of meandering rivers continues to attract considerable attention in research and for practical applications, given that it is closely associated with the safety river systems riparian zones. There has been much discussion regarding various channel planform features exhibited by under different conditions. Yimin River a good example located southeast Hulun Buir Grassland, which characterised fragile ecosystem little anthropological activity along active flow during non-frozen season from May November each year relatively low sediment discharge compared Yellow Mississippi River.
