Since the implementation of the “clearing the four chaotic behaviors” campaign in rivers and lakes

shoreline management of key water bodies in Guangdong Province has seen significant improvements. However

a considerable number of embankments still exist within river channels. Most of these embankments are unregistered

unlicensed

and unmanaged（“three-nos” facilities）

posing serious challenges to flood control and water safety. Therefore

studying their remediation is of great significance for promoting sustainable socio-economic development. This paper systematically reviews the distribution

historical formation

current management status

and existing issues of embankments along major rivers in Guangdong Province. It conducts comparative analysis across different regions

identifies commonalities and differences

and

drawing on relevant experiences

proposes targeted remediation strategies. The findings reveal that embankments are complex historical legacies resulting from land-use conflicts between human development and water systems. Given their socio-economic entanglements

a one-size-fits-all solution is impractical. A coordinated

classified remediation approach is recommended

which should be integrated with ecological restoration of riverine and riparian zones to achieve both functional and environmental benefits.
