Abstract
A method for computing an index on a sediment disaster, performed by a computer, the method includes: creating a computation model for computing the index on a sediment disaster at a specific point using information on a geometry of a precipitation zone at the specific point and long rainfall and short rainfall at the specific point, the information being created from past precipitation data accumulated in a storage unit; and computing the index on a sediment disaster using the computation model from the information on the geometry of the precipitation zone at the specific point, the information being created from the input precipitation data.
