A Water Management Strategy based on Efficient Prediction and Resource Allocation

The paper mainly deals with a water programming case to make sure that water resources can meet the use of China's demand from the year 2013 to 2025. Firstly, based on the second exponential smoothing method, we find that the demand for freshwater is about 616.0 billion cubic meters, while the water resource is about 531.3 billion cubic meters for the year 2013. Secondly, to calculate the water supply, we classify the water resource into 3 categories: surface water, underground water, and others, with different ratios for consumption. Thus, of all provinces, Guangdong and Jiangsu will suffer the water scarcity most when compared with the water demand. Last, we put forward a Water Resource Allocation Model (WRAM) aiming to minimize the cost of the water allocation problem, which is about3.57961 billon RMB in 2013 and 3.5756 billion RMB in 2025.
