Knowra North Jiangsu Main Irrigation Canal North Jiangsu Main Irrigation Canal The North Jiangsu Main Irrigation Canal is a major waterway in Jiangsu, China, carrying water eastward from Hongze Lake toward the Yellow Sea for irrigation, drainage, and flood control.
Hongze Lake : A large freshwater lake in Jiangsu, China, connected to the Huai River system. The canal begins at this lake, which supplies water for its eastward flow.
Agriculture in Jiangsu : The cultivation of crops and raising of livestock in Jiangsu Province, China. Canal water supports agricultural production across parts of northern Jiangsu.
Huai River management : The engineering and administrative efforts to control flooding, drainage, and water use in the Huai River basin. The canal is part of the regional works developed to manage water in the Huai basin.
Flooding in the Huai River basin : Periodic inundation caused by high flows and rainfall across the Huai River basin in eastern China. Canal operations contribute to managing floodwater in a basin with a long history of floods.
Huai River : A major river in eastern China flowing through Henan, Anhui, and Jiangsu toward the Yellow Sea. The canal forms part of the broader water-management system that regulates Huai River flooding.
Water management : The planning and operation of water resources to meet human and environmental needs. The canal is infrastructure within Jiangsu's broader system for allocating and controlling water.
Yellow River course changes : Historical shifts in the Yellow River's channel, including changes that altered its route to the sea. Changing river courses reshaped northern Jiangsu's flood and drainage challenges.
Coastal wetlands of Jiangsu : Wetland habitats along Jiangsu's coast, shaped by sediment, tides, and freshwater flows. Altered freshwater delivery toward the coast can affect nearby wetland conditions.
Canal lock : A gated chamber that raises or lowers vessels between stretches of water at different elevations. Locks and control gates help manage water levels and movement along engineered waterways.
Waterlogging : The saturation of soil with excess water, which can damage crops and restrict land use. Drainage through the canal helps address waterlogged farmland in low-lying areas.
