基于GIS的平原河网非恒定流计算模型

GIS-based unsteady flow calculation model for plain river networks

运用矩阵标识法求解节点水位方程,并结合地理信息系统(GIS)技术建立的平原河网非恒定流计算模型,具有节省河网基础资料的前处理和提高计算工作效率的特点.

By using the matrix mark method to calculate the node-stage equation and GIS techniques, an unsteady flow calculation model for plain river networks is developed. The model can save pre-treatment works of network′s basic data and improve calculation efficiency.
