Benggang is an unique type of soil erosion in the south of China, which refers to the erosion phenomenon of collapse and scouring of the hillside damaged by the combined action of hydraulic force and gravity. Bengngang erosion is an advanced stage of gully development and is a permanent gully that can"t be filled in by farming practices. Benggang mainly occurs in the southern granite hill region which is mostly agricultural production, and its harmful effects are serious, destroying land resources, affecting agricultural production, and seriously impeding the coordinated and sustainable socio-economic development. Due to the complexity of the factors involved in the formation of Benggang, the knowledge of the mechanism and the management measures are still being explored. The objective of this study is to identify the current status of soil erosion in the region by outlining the survey methods of Benggang erosion, to obtain basic information on Benggang erosion, and to provide a scientific and theoretical basis for the development of soil and water conservation measures. Specifically, this study detailed the methodology, content, and purpose of individual Benggang surveys, and through this process grasps the basic characteristics of Benggang erosion. Subsequently, the methodology of investigating the regional influencing factors of the Benggang was introduced, which mainly includes the main influencing factors of the Benggang, such as geological geomorphology, climatic conditions, soil parent material, vegetation, and anthropogenic activities. On the basis of the investigation, this study also compiles the monitoring techniques of the Benggang used in recent years, combining the traditional manual methods with the emerging technologies to truly and efficiently grasp the distribution characteristics, influencing factors and erosion development trend. Then, the research progress on the risk assessment and prediction methods of Benggang was reviewed to objectively assess the losses or impacts caused by Benggang disasters and to explore preventive and control measures. Finally, existing measures and models for the prevention and control of Benggang are discussed on the basis of the survey of basic information on Benggang, field monitoring methods and risk assessment and prediction studies. The above investigations and studies are conducive to the understanding of the current situation of erosion and the prediction of the development trend of Benggang, which is of great significance to the prevention and control of erosion in the Benggang regions in China. The contents of the review in this study also assist in providing a basis for methods of investigation in the same erosion types, which can be generalised to the research of soil erosion in regions with similar geomorphology.
