Groundwater-river interactions and vegetation dependency in water scarce environments
UNESCO-IHE is partnered with Eijkelkamp, China University of Geosciences, Hohai University, and the Xi'an Geological Survey to form the "Partnership for Education and Research in Water and Ecosystem Interactions", as part of the Asian Facility for China Project. On Wednesday 29 February at 13:45, an Information Dissemination Seminar will take place in Auditorium A1A, entitled: Groundwater-river interactions and vegetation dependency in water scarce environments. Prof. Stefan Uhlenbrook will act as Chair.

HIGHLIGHTS
The project “Partnership for Education and Research in Water and Ecosystem Interactions” was financed by Dutch Government Asian Facility for China programme, and was implemented between 2009 and 2011. The project has established a joint Sino-Dutch Research Centre for Ecohydrology at China University of Geosciences, Beijing, and set-up field research sites in the semi-arid Hailiutu River catchment in Erdos Plateau, NW China. In this project seminar results of the field research are presented. Interactions of groundwater-river were systematically studied with hydraulic method, temperature measurements, seepage and discharge measurements, and use of isotopes and hydro-chemistry. It concluded that almost 88% of the river discharge is originated from groundwater seepage. Vegetation water use was measured with sap flow sensors. Dynamics of sap flow are correlated very well to climatic factors and water sources. The total evapotranspiration consumes around 90% of the annual precipitation. These research findings have significant implications for monitoring and management of water and vegetation in the Hailiutu River catchment.
