Zhāng Guówéi 張國維 (1595–1646), zì Jiǔyī 九一, hào Yùsì 玉笥, of Dōngyáng 東陽 (Jīnhuá, Zhèjiāng), was a major late-Míng hydraulic-engineer-administrator and Míng-loyalist. Jìnshì of Tiānqǐ 2 (1622); served as Yīngtiān (Nánjīng) Governor 1635–1641, where he directed major hydraulic projects on the Sūzhōu Jiǔlǐ stone dyke, the Píngwàng dykes, and the Sōngjiāng tide-protection levée. Promoted to Gōngbù yòu shìláng with concurrent Zǒngdū hédào (Director-General of the Waterways), in which capacity he dredged canal channels to maintain the grain-transport during drought. He rose under the Prince of Fú at Nánjīng to Lìbù shàngshū; was imprisoned in 1643 after the collapse of the eight-Generals’ armies but pardoned in recognition of his river-management merit. After the fall of Nánjīng (1645) he followed the Prince of Lǔ at Shàoxìng; on the collapse of that loyalist regime in 1646 he drowned himself. His principal hydraulic monograph is the Wúzhōng shuǐlì quánshū (KR2k0071) in 28 juan, the most extensive late-Míng compendium on Jiāngnán hydraulic engineering.
