Resumen
Many large-scale water transmission projects, such as China?s South-to-North Water Transfer Project, are hundreds of kilometers long and need real-time regulation applications for management and control. This requires the calculation model to have higher calculation accuracy and faster calculation speed. The existing calculation models are difficult to take these two aspects into account at the same time. In this paper, the accuracy and efficiency of one-dimensional model algorithms are studied and compared, and the best calculation scheme is summarized.
