  • We applied Nearest-Neighbor Method (NNM) to water level forecast of long lead-time at a flooding event. NNM is a non-parametric scheme that a pattern-matching technique. The water level at the Ishikari Ohashi Bridge site, which is a standard observation point on the Ishikari River, were estimated for lead times of 1 hour, 3 hours, 6 hours and 12 hours for the 2001 flood, which was the most severe in 20 years. Although NNM is a very simple scheme that uses past records, it greatly outperformed a method based on the water level correlation between the subject site and observation sites upstream of it for a large river. NNM was proved to be of practical use in forecasting flooding of long lead-time and short computation time.
