Grey prediction model for water withdrawals

摘要

Since grey prediction model performed well in feasting with few data, we applied it to predicting water withdrawals. We take the prediction of the water withdrawals in the United States as an example. With the data of water withdrawals in the past 30 years, we forecast how much fresh water will be needed in main states of America, which is crucial for the government to make major constructions in national economy. Moreover, we test the model by applying it in the prediction of annual water use in Chinese main river valleys.
