IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Rational Allocation of Water Resource towards the Low-carbon Development Mode in Baiyangdian Basin
Author : Tianling Qin, Denghua Yan, Hao Wang, Baisha Weng, Zhiyong Yang, Chuanzhe Li and Gang Wang
With social and economic development, carbon emissions mainly caused by fossil fuel consumption keep increasing. At the same time, the over exploration of water\land resources and occupancy of ecological water use have reduced the carbon-capture capacity of the ecosystem. These two situations result in the increase of regional net carbon emission. The rational allocation of water resources towards low-carbon development mode sets up the connection between carbon cycle and water resource system, which is based on the relationship between carbon emission and socio-economic water use and the relationship of carbon capture and water demand for ecosystem. It makes use of water saving measures to decrease the socio-economic water use and carbon emission. Furthermore, through the joint allocation of water resources and net carbon emission, it curbs the carbon emission and guarantees a better water supply for the ecosystem, which therefore strengthens the carbon capture capacity. Based on the generalization of regional carbon-water coupling system, it establishes the rational allocation model of water resources towards low-carbon mode and applies the model in the Baiyangdian Basin. The results indicate that water supply could not meet regional demand during 2005-2010 when the whole basin was carbon ?source? due to increasing benefits of net carbon emission per cubic meter of water. If the economic-social development mode is extensional in the planning year of 2020, the high water-saving allocation scheme should be recommended, of which water deficit, amounts of carbon emission and net one will be reduced by 28.45%, 11.9% and 13.5% respectively. If it is low-carbon mode, medium water-saving scheme should be recommended and the above three targets will be reduced by 28.45%, 60.1% and 74.9%.
