Zhexi shuili shu 浙西水利書 "Water conservancy of the Zhexi region" is a book on water control written during the early Ming period 明 (1368-1644) by Yao Wenhao 姚文灝 (jinshi degree 1484), courtesy name Xiufu 秀夫, style Xuezhai 學齋, from Guixi 貴溪, Jiangxi.
Yao was 常州府通判、湖廣提學僉事、工部主事提督浙西水利。. His 3-juan-long study on irrigation in the region of Lake Taihu 太湖 in Jiangsu (Zhexi is the region between Lake Taiku and River Qiantang 錢塘江) quotes from a lot of older writings on the issue. It was finished in 1497. The text is accompanied by commentaries added by the compiler. The text is divided along chronological lines and assembles information from the Song 宋 (960-1279), the Yuan 元 (1279-1368), and the then-present period. All periods are dealt with in roughly in the same intensity, with 20 chapters on the Song, 15 on the Yuan, and 12 on the Ming period, resulting in 47 chapters. Yao tried to select statements that were proven in practice, and discarded passages including wrong information.
