Abstract: Babuli gully is located in JinChuan city,the upstream of Dadu river. Debris flows had occurred many times in this gully in history. Since 1980s, the government has taken countermeasures to manage the debris flow using the check dam and drainage canal and gained a great effect. After nearly 30 years of evolutions, the mitigation project together with the debris flow disaster are forming a unique silt resource and processing a preliminary development on the exploitation. This study carried out analyses on the characteristics of resources, the limitations to the general exploitation, the optimized configurations for the development and the protection, and the further development spaces. The results suggested that the development of sediment resources has extended the use period of check dam, the economical forest plant suppressed the debris flow disaster, the dam leveled up the gully bed to provide the water power for a electricity development and farmland irrigation, and economical and the mitigation forms a positive cycle, achieved a sustainable development. The project aims to advance the resources usage, to maximize the economic efficiency and social efficiency, to further the usage for current project to establish debris flow preventing and controlling science base, to build a restriction zone on both sides of gully front's accumulation fan debris flow drainage project, to build an ecological park and to optimized resources development.

Key words: Babuli gully, debris flow, mitigation engineering, resources development
