灌区水网动力学模型(SkyHydid)构建及验证
Construction and validation of a hydrodynamic model for irrigation canal systems(SkyHydid)
摘要
Abstract
The water network in irrigation districts comprises one-dimensional rivers/canals/ditches and two-dimensional farmlands.Under the influence of complex control combinations involving gates,dams,and pumps,the hydrodynamic processes exhibit distinct cross-dimensional characteristics,making it difficult to conduct related dynamic simulations and analyses using classical coupling methods.To address this challenge,this study proposes a unified mathematical representation approach by discretizing both the one-dimensional river/canal/ditch network and the two-dimensional farmland using a unified grid.Hydraulic structures such as gates,dams,and pumps are treated as internal boundary conditions,and the flow is driven by potential energy gradients.The water diffusion coefficient is used to distinguish the specific regions in which water movement occurs,forming a unified representation method for the dynamics of irrigation district water networks.The model is validated using field data from the northern part of the Qinglongshan Irrigation District in Heilongjiang Province,covering both canal networks and farmlands.Results show that the average relative error between the simulated and observed ponding depth in paddy fields and water depth in canals is less than 5%.The average relative error between the simulated canal flow and the measured flow using ACDP is also less than 5%,indicating that the proposed unified dynamical representation method can effectively reproduce the hydrodynamic processes of both canal networks and farmlands.This provides a practical tool for the simulation and analysis of irrigation district water networks.关键词
