This collection documents engineering efforts to control Chinese rivers. Following a devastating flood in 1917, the Chinese government sought help from Western experts. Documents from the years 1919 to 1923 include H. van der Veen, "Floods in the Plain of North China: Their Causes and How to Mitigate their Effects"; transcripts and oversize plans by John Ripley Freeman pertaining to "General Specifications for the Design and Construction of the Yellow River Bridge," 1920-1921; a Chinese translation of Freeman's work on controlling the Huai River, 1923; and Hubert Engels, "The Regulation of the Hwangho," also 1923. In an attempt to stop the Japanese from invading in 1938, the Chinese blew up levees on the Yellow River, flooding 9000 square miles, killing or starving one million people, and leaving twelve million homeless. A flood of 1943 destroyed crops, starving three million people. The bulk of the collection concerns this latter period. Documents include a "A Project for the Control of the Yellow River and Construction of San Meng Shar Dam," circa 1940; a preliminary report on soil, water, and forest preservation in northwest China, 1943; and reports of extensive studies of hydrology, geology, and the regulation of the Yellow River, the lower Yellow River, the Yellow River Basin, and the Sanmen Gorge (1946-1947).
