摘要：Aiming at the hydraulic problems existing in the operation of the two lakes in the east route of the South-to-North Water Diversion Project, a one-dimensional hydraulic equation and a pump station performance equation were coupled. Based on the Fortran language, a simulation model for water delivery scheduling of the two-lake cascade pumping stations was developed and combined with the actual measurement from 2013 to 2017. The data has been calibrated for the model, which can simulate the hydraulics of different water transport conditions. Based on the hydraulics method, the hydraulic loss under normal water conveyance conditions between channels was analyzed, calculated and studied. In view of the aquatic problem, Changgou-Denglou section was selected as the research object, and the model was combined based on the measured data. The hydraulic loss under the plugging condition of the aquatic plant was analyzed and calculated and the law was studied. Based on the water balance method, the water loss in the two lakes was analyzed and calculated. The research results can provide reference for the operation of the two lakes in the east route of the South-to-North Water Diversion Project.
