The degradation of stream banks is an environmental concern for many people, especially property owners along stream banks.

Riverbanks erosion is a very important issue during flood periods and the risks associated to it demand that protection measures are taken and, in certain cases, that protection structures are built.. 

soil bioengineering methods are commonly used for riverbank protection in river restoration works. Yet all such work revolves around one main issue: the limit of resistance to hydrodynamic stress. Tests show that different soil bioengineering methods produce different resistance levels and that the best results are obtained by methods which include the entire riverbank. The stability of soil bioengineering methods is also influenced by a number of dynamic and local factors.

Traditional concrete revetment technology mainly focuses on the safety of engineering without taking the river ecological system protection into account. The ecological concrete revetment can properly combines the river slope sclerosis with green to keep the river ecological system sustainable develop. Ecological concrete revetment includes excavating, laying concrete frame, pouring ecological concrete, filling nutrition soil, planting vegetation, management and observation processes. The revetment of concrete hexagonal tile is suitable with excellent resistance to water washing out and good capability of fixing soil. Slop protection of concrete rectangular frame is used for its large scale and high efficiency of construction. Selecting native plants for greening materials is convenient of transplanting, it has low cost and high survival rate.
