Liu Guangwen, July 30, 1910 –March 6, 1998


Professor Liu Guangwen, a native of Hangzhou City, Zhejiang Province in China, graduated from the Department of Civil Engineering of Tsinghua University in 1933 and stayed on as an assistant professor in the Department of Civil Engineering. In 1936, he was admitted to study in the United States at public expense. From 1936 to 1937, he studied water conservancy engineering at the University of Iowa and obtained a master's degree in water conservancy engineering. From 1937 to 1938, he studied hydraulic engineering and applied mathematics at the Technical University of Berlin in Germany. After returning to China in 1938, he successively taught at Guangxi University, Chongqing University, Fudan University and Shanghai Jiaotong University. In 1952, colleges and universities across the country adjusted their faculties, and concentrated the civil and hydraulic teachers of Nanjing University, Shanghai Jiaotong University, Zhejiang University, Tongji University and other schools in East China, and established East China Water Conservancy College (now Hohai University) in Nanjing. In the same year, Mr. Liu Guangwen was transferred from Shanghai Jiaotong University to East China Water Conservancy College as a professor. He was responsible for the establishment of China's first terrestrial hydrology and hydrology department, and served as the head of the department and honorary department head.

Hydrological Achievements[edit]

Professor Liu Guangwen was the founder of higher education of hydrology in China. He devoted his life to the teaching and scientific research of hydrology, edited the most influential works, translations and textbooks such as "Hydrological Analysis and Calculation", "English-Chinese Hydrological Glossary", "Applied Mathematics", "Hydrological Statistics and Approximate Calculation" and other books, translations and textbooks, reviewed the "Hydrological Statistics Commonly Used Charts" " and published many high-level papers.

Liu Guangwen was an innovator in applying the theory and method of mathematical statistics to the study of probabilistic characteristics of hydrological events. He founded the problem of parameter underestimation when fitting P-III distribution and proposed the “Numerical integral single weighted function method” and “Numerical integral double weighted function method” for parameter estimation. He wrote the book Hydrological analysis and calculation (China Industry Press, Beijing, 1963). He was the consultant of the Expert Group for the Demonstration of the Three Gorges Project on the Yangtze River. He not only used mathematical statistics theories and methods to study the design flood of the Three Gorges, but also advocated the use of the probable maximum precipitation/probable maximum flood (PMP/PMF), ancient flood and other ways. He put forward a new idea of using the concept of "weather combination" to calculate the probable maximum precipitation.
