Sediment-related disasters are caused by various factors. A multi-discipline and multi-department cooperation is important to construct the warning engineering system on sediment-related disasters. Most of the sediment-related disasters are induced by rainfall. Based on the regressive relationship between the disaster occurrence and rainfall, a meteorological-statistical potential forecast model for sediment-related disasters is developed as part of a joint project undertaken by China Meteorological Administration (CMA) and Ministry of Land and Resource ( MLR). The forecast has been launched into operation since June 1，2003，when a nationwide sediment-related disasters warning system via public media was set up by CMA and MLR. In this paper the forecast and warning system is reviewed and some valuable suggestions are presented.
