The low hilly area binary
water cycle model construction method based on topological network division belongs to the technical field of
water cycle model construction, and aims to solve the problems that the existing model is difficult to adapt to the complex
terrain hydraulic characteristics of low hilly area, the natural-social binary
water cycle coupling is insufficient, and the long-
time sequence simulation precision is poor; the present application obtains multi-source heterogeneous data, divides the minimum hydrological unit and constructs a four-level
water supply topological network; the key parameters are extracted by the binary driven analysis model, and the synergistic effect of
terrain and human activities is quantified; the core parameter matrix is generated through topological
adaptation coupling model and multi-objective optimization; the complete model is constructed by fusing the improved distributed hydrological
simulation and social
water use regulation module, and the
dynamic coupling simulation of binary water cycle is realized by combining multi-index calibration and parameter dynamic updating. The present application accurately describes the complex
hydraulic connection and human activity
intervention effect, improves the simulation precision and long-
time sequence adaptability, the model has strong
operability, wide application range, and provides reliable
technical support for efficient utilization and management of
water resources in low hilly area.
