Abstract：From 2003 to 2016, a total of 13 valid topics were identified by LDA(Latent Dirichlet Allocation)topic model through the collection of 1405 Chinese documents related to the South-to-North Water Transfer East Route Project.The topics include "engineering construction","pump station operation optimization", "water pump performance study", "engineering cost research","water environment model","river water pollution","information automation","lake eutrophication", "water pollutant","pump structure calculation","pump hydraulic calculation","ecology" and "ecological environment management".Two novel bibliometric indicators, including topic proportion and topic trend, were constructed to describe the academic concerns of the South-to-North Water Transfer East Route Project, ifnding that "engineering construction" is the most popular topic, followed by "pump station operation optimization" and "water pump performance study". However the "water environment model" and "lake eutrophication" are becoming a hot topic. The results reflect the attention of the academic circles and provide the basis for the post-evaluation of the South-to-North Water Transfer East Route Project.
