Discuss what type of ecological bank protection is better for river management? Let's all talk...

This question is actually difficult to answer. The forms of slope protection you mentioned are commonly used now. Specific issues need to be analyzed in detail. In addition to economic factors, the type of slope protection used is also related to many factors. For example, where is the slope protection located? Is it a rural section or an urban section? What is the flow rate of the river? What is the sediment transport situation of the river flow? What is the climate of the project area? Different factors have requirements for the form of slope protection, so just choose the most appropriate one. In addition, I would like to remind everyone that in areas with unstable water levels, try to avoid using "six-sided grids filled with gravel" slope protection. After a flood, it is basically unrecognizable. I have seen the real scene. Personally, I think it is better to use soft and erosion-resistant forms such as gabions or dry stones below the design water level, and it is better to use other more beautiful ecological slope protection for the above parts.
