Short summary
Typhoon inundation forecast model for a gauging network is proposed. Model inputs are identified by cross-correlation and mutual information analysis. Optimal ARMAX model structures are searched for considering three objective functions, including the forecasting capacity in water level throughout the event, the accuracy in forecasting peak water levels and the time at which peak water levels are likely to occur. Characteristics of the resultant models subject to various objectives are examined.
