Abstract:
On the basis of water resources system analysis and characteristics of hydrology and water conservancy projects, the precipitation and runoff model, hydrodynamic model, water quantity allocation model, and water project scheduling model were constructed to investigate the water resources quantity and water supply and demand in the river basin. Water conservancy pro2 ject scheduling scheme was proposed based on the constructed models and applied to perform reasonable allocation of water re 2 sources in the study area. T he water supply, water demand, and water deficit in agriculture, industry, life, ecology, and lock under the current and planning engineering conditions were simulated, and the corresponding allocation schemes of water resources were established. T hrough the comparison between the current and planning conditions, water supply capacity can increase while water deficit can decrease after the implementation of the first stage of the South2to 2North Water Transfer Project. Under the assurance rates of 95%, 75%, and 50%, annual water deficit rate decreases by 10. 3%, 8. 0%, and 5. 2%, respectively. T he re 2 search can provide scientific reference for the water conservancy project scheduling in the Eastern Route of the South2to 2North Water T ransfer Project, and is of significance for the water resources allocation and scheduling of the inter2basin water conser2 vancy project.
