Jìn Fǔ 靳輔 (1633–1692), zì Zǐyuán 紫垣, posthumous Wénxiāng 文襄, was the principal Qīng Zǒngdū Hédào 總督河道 (Yellow River Commissioner) of the Kāngxī period and the practical implementer of Pān Jìxùn 潘季馴’s late-Míng shùshuǐ gōngshā hydraulic doctrine for the early Qīng. From the Xiānghóng 鑲紅 Banner of the Hànjūn (Chinese-bannered) division, he was originally given a Hànlínyuàn xiūzhuàn 翰林院修撰 appointment, then transferred to provincial-administration. He was elevated from Ānhuī xúnfǔ to Zǒngdū Hédào in Kāngxī 16 (1677) at the height of the Yellow-River crisis when the river had broken through Gāojiā yàn 高家堰 and the lower Yellow River and Huái converged eastward into the sea, abandoning the historical channel.
Jìn served three terms as Zǒngdū Hédào (1677–88, with brief intermissions), in close partnership with the deputy Chén Huáng 陳潢 — the actual hydraulic theorist of the team. The JìnChén program was Pān Jìxùn’s principle made operational: confine the Yellow River to a single channel between high embankments, scour silt by raising channel velocity, integrate Yellow River and Grand Canal management. Their construction works included: the Zhōnghé 中河 (Middle Canal) and Zàohé 皂河 — major new channels providing the critical Yùnhé (Grand Canal) bypass of the unstable lower Yellow River; the Yáodī 遥堤 and Lǚdī 縷堤 (multi-tier dyke system); the rebuilt Gāojiā yàn and the Zháibà 翟壩 closure works; and the six Jiǎnshuǐ (water-reduction) overflow gates.
The Sìkù tíyào gives the canonical summary of his hydraulic doctrine: “zhù dī yá, shū xiàliú, sāi juékǒu — yǒu xiānhòu ér wú huǎnjí” (build embankment-cliffs, clear the lower-flow, plug the breaches — there is order of priority but no relaxation). The works produced the Kāngxī-era stabilization of the Yellow River — the foundation of the eighteenth-century consolidation.
His memorials are preserved in the KR2f0035 Wénxiāng zòushū 文襄奏疏 in 8 juàn (with the appended Fǔ Wǎn tígǎo 撫皖題藁 of one fasc.), edited by his son Jìn Zhìyù 靳治豫. Qīng shǐ gǎo j. 279 has his biography. CBDB id 57335 (1633–1692).
