Short summary
We attempted to evaluate the risk of a sediment disaster using the SMD, i.e., the surplus capacity of the soil column to accept rainwater. A numerical model was developed to calculate the SMD and then applied to 446 sediment disasters. The results showed that the SMD can be a good indicator of the risk of sediment disaster. Also a probability distribution model of the minimum SMD within the disaster occurrence period was constructed which allows early warning of the sediment disasters.
