Research on Optimal Allocation of Water Resources in Handan City Based on the Refined Water Resource Allocation Model

In order to realize the dynamic regulation and control of regional water resources alleviate imbalance between supply demand resources, on basis refined management General Water Allocation Simulation Model (GWAS) Handan City was constructed. The research optimal allocation in different regions counties under normal dry years planning (2025 2035) carried out. results show that allocated volume 2025 is 2.248 billion m3 2.150 m3, respectively, shortage rate 11.72% 22.11%, respectively. mainly agriculture. 2035, volumes will be 2.504 2.33 rates 4.50% 21.84%, After optimized allocation, structure significantly improved. proportion groundwater decrease at each level year, external transfer unconventional increase. This can provide technical reference development scheme depending future, as well other cities Beijing–Tianjin–Hebei Region.
