BFP11. Water-use accounts in CPWF basins: Simple water-use accounting of the Yellow River Basin.

Abstract

This paper applies the principles of water-use accounts, developed in the first of the series, to the Yellow River basin in China. The Yellow River rises in the Bayan Har Mountains in Qinghai Province in western China, and empties into the Bohai Sea. A unique feature of the river is the large amount of silt it carries.

Net runoff is about 14% of total precipitation. Forest and woodland cover 9% of the basin and use about 15% of the precipitation. Grassland covers much of the upper part of the Basin, consuming about 42% of the precipitation. Irrigated agriculture covers just 6% of the Basin and uses about 11% of the water.

The effect of increased irrigation efficiency shows that local increase of irrigation efficiency does not necessarily translate into changes at the whole basin level. The water transfer to the Yellow River from the Yangtze boost flows to the upper Yellow river and leads to an increase in the flows throughout the river.
