A Supply-Demand Model on Allocation of Water Resources

摘要

Two basic models are constructed in this paper to study water scarcity. The first model demonstrates an intuitive association between water supply and demand. The second model illustrates how to achieve the optimal allocation of water resources through our intervention. Taking Southwest America for example, this paper analyses the water scarcity condition by using supply-demand model and then gives qualitative analysis of inter basin water transfer. Conclusion shows our model has positive effect on alleviating water resources scarcity and making the distribution of water resources more reasonable. In the end, this paper analyses some strengths and weaknesses of our model to make the model more practice and applicable.
