Multi-object dynamic management model of water resources system for the Longkou City, Shandong Province

Based on the fact of water resource ineffective management, the dynamic management model of using water being suitable for complex condition of multiple water sources, and water works and users is built. The method for adjusting plan index of using water is come up with, by forecasting the water supplied and demanded in rolling monthly and optimizing regulation water resources in time. The sub-model of allocating water resource among enterprises is put forward according to the water saving level and importance of using water. And the sub-model of water quantitative evaluation is also put forward according to reduction of gross industrial production value and the yield of main irrigated grain because of water shortage in different months. The calculation results show that the model and method are feasible and practicable.
