Abstract: As an important part of water resources, the available amount of water resources is one of the main factors restricting the rapid development of regional social economy. Based on the General Water Allocation and Simulation for Management System (GWAS), this paper constructs a regional water cycle model. Taking Yueqing City as an example, different hydrological units are modeled to study the amount of water resources. Comparing the actual measured traffic data to verify the accuracy of the model, Nash coefficient is 0.9234, water resource error rate is 1.7%, model fitting results are good. The deduction method is used to deduct the ecological water demand and the amount of abandoned water in flood season to determine the available amount of surface water resources under different hydrological years. It can be used as an important basis for the revision of river basin or regional planning, water allocation and scheduling, and total amount control index revision in the future.
