Water-saving Potential Analyses on Large-scale Gravity Irrigation Districts in the Yellow River

摘要：

Irrigation districts are the major water consumer in the Yellow River, which has annually diverted about 90％ of the total water consumption of the whole basin in average. Restricted by economical condition, facilities of irrigation districts and management method and so on, the irrigation water badly wastes and the water utilized coefficient is lower, generally under 0.5, greatly exacerbating the conflict of water resource shortage. According to the current water using condition of the Yellow River irrigation districts, this paper has put forward the concept of water saving potential and the corresponding analyzing and calculating method, and then analyzed water saving potential of the large- scale gravity irrigation districts in the Yellow River.
