Abstract: Provided is a risk assessment method for sediment siltation induced by blocking projects in a mountainous small watershed. Based on resilience disaster mitigation, a four-stage macroscopic analysis model is constructed from full-life-cycle perspective of blocking project measures, including advance preparation, resistance and absorption, response and adaptation and resilience recovery. The latter three risky stages are projected as three assessment windows, namely, pre-full siltation period, full siltation period, and post-full siltation period. Slope erosion and siltation hazard degree, blocking engineering structure vulnerability degree, and control measure resilience degree are introduced to assess risk levels of the three assessment windows; and flowing zone risk degree index is used to assess full-life-cycle comprehensive risk level.
