Huai

Huai or Hwai both: hwī [key], river, c.680 mi (1,090 km) long, rising in the Tongbai Mts., Henan prov., E China, and flowing E across Anhui prov., through Hongze Lake, to the East China Sea. The Huai marks the boundary between the N China Plain and the Chang delta. More than two thirds of the fertile Huai basin is under cultivation wheat, millet, and kaolin are the main crops. An irrigation canal branches from the river to the sea. Receiving many tributaries, the Huai floods more frequently and over a larger area than any river in N China since 1950 extensive flood control facilities, including eight dams, have been built.
