About CCTW

Introduction of WEMST

Upon finishing construction, the Three Gorges Reservoir (TGR) hasattracted worldwide attention. Many are astonishing for the sheer volume ofconserved water and the elephantine dame body, but the truly imminent problememerges: How can we protect the rich and diversified TGR ecosystem and localenvironment? It is a necessity to introduce innovated technologies andmanagement ideas to explore and preserve the local plant species, soilproperty, water quality and stabilizing regional climate.

Chongqing Municipal and Windsor University take hands together tosupport the research of TGR protection, and The China-Canada Three Gorges WaterScience Centre (CCTW) is found for that purpose. As the only institutionpurports at preserving the ecosystem of TGR, CCTW is now committed to bridgingthe research of hydrology conservation at TGR with other similar institutionunder a worldwide scope. CCTW belong to the International Science andTechnology Cooperation Demonstration Base of National Science and TechnologyCooperation of China, which is the only national water resources base in theYangtze River mainstream, and the opening mechanism designation for jointresearch team will lay a concrete foundation for future research of waterresources utilization and soil protection of TGR.

Aim and background:

TGR is one of the biggest man-made water bodies, the originalhydrology and ecosystem were fundamentally changed since late 2019 when about630 km of river channel was impounded with 40 billion cubic meters of waterafter the construction of Three Gorges Dam (TGD). The water quality andregional ecosystem are

overshadowed by the high-populated residential area, hillyterrain, slope farmland, and the vast alternated submerged zone. The uniquewater allocating management make no references for TGR and renders a challengefor the hydrology research scholars worldwide. Given the enormous environmentchange latitude and complexity of TGR, a comprehensive, cross-disciplinary andmost of all, ecosystem-based research system is in great need to ensure thewater quality conservation, ecological protection and sustainable developmentof TGR watershed. The water of TGR is eutrophic for a long time, according to asurveying of CCTW, and it is the hydrological incentives that lead to such aresult. Furthermore, the stratified water layer during water storage period isan essential factor in the formation of water bloom in branches. A paucity ofpractical methods makes the quantifying and evaluation of water quality at TGRdifficult. Equip with advanced technology derived from internationalcorroboration, an early warning system can be established and the correspondingresearch can provide valuable references for the water purification andpollution control.

Eutrophication, non-point pollution, and land-water protection areglobal environmental issues. Lake Erie, one of the Great Lakes, was a “deadpool” in the 1970s. Through decades of efforts, Lake Erie finally became animportant fishing farm and drinking resource at the beginning of this century.But a series water bloom appeared at 2010 and the polluted water leads to awater shortage in Ohio State. Similar cases can be found in therivers/reservoirs of Europe and Australia, which require a great deal of humanand monetary resources to mitigate or reverse the situation.

Longwanggou watershed, located in Nantuo Town, Fuling District,Chongqing, is close to the Yangtze River mainstream. The main crops are rice,corn, mustard and citrus. The long-term high fertilizer production mode leadsto soil degradation and a large amount of chemical fertilizer leaching, and theagricultural non-point source pollution is very serious there. The monitoringstation in the watershed can not only automatically acquire the samples offarmland surface runoff and interflow all day to monitor soil nutrients, butalso complete the farmland dripping with the fertilizer drip irrigation systemand the automatic pump according to the fertilization scheme designed by theresearch group. The Non-point Source Pollution Remote Automatic MonitoringStation technology originates from the Greenhouse and Processing Crops ResearchCentre, which is a Canadian agricultural site besides Lake Erie in southernOntario.

WEMST purport at promoting international cooperation and breakingdown the constrictions of discipline and nationality to foster the research ofwater conservation. A global scope is taken to assimilate the successfulmanagement system of huge water body protection and explore the TGR-suitedwater monitoring and conservation theory and practices. The research outputscan provide theoretical and practical references for similar watershedregarding water conservation’s worldwide affection.

Participating institutions:

University of Waterloo, University of Windsor, Yunnan University,Yunnan Normal University, Three Gorges University, The Ministry ofAgriculture's Center for Greenhouse and Facility Agriculture, the DanishInstitute of Water Resources, the New Zealand Institute of Geology and NuclearSciences, Australian Commonwealth Scientific and Industrial ResearchOrganization Ministry of Lands and Water Resources.

Propose programs:

Based on TGR water resources and maintaining the continuousinternational cooperation, exploring the purification and conservationtechnologies of the water body, and establishing an early warning system forwater quality degradation. Promoting the WEMST as the base ofwater-land-ecosystem research and cultivating international researcher of waterresources management.
