APPLICATION OF GREY MODEL TOWARD RUNOFF FORECASTING

摘要

A reliable forecasting model is essential in real-time flood forecasting for reducing natural damage. Efforts to develop a real-time forecasting model over the past two decades have been numerous. This work applies the Grey model to forecast rainfall and runoff owing to the model' s relative ability to predict the future using a small amount of historical data. Such a model significantly differs from the stochastic and deterministic models developed pre- viously.
