WCFM Research Projects
The Research Strategic Vision of the Waterways Centre for Freshwater Management (WCFM) is to “integrate disciplinary water research to provide interdisciplinary solutions to freshwater management problems”. The Centre currently hosts two key projects;
The Selwyn Waihora catchment is a complex catchment which is representative of freshwater issues facing communities and decision makers across New Zealand. Issues include intensification of agricultural land use resulting in an increase of non-point source contaminants such as nitrogen, phosphorus, and pathogens such as e-coli into both surface and ground water. Demand on water resources has grown, particularly for groundwater to supply irrigation. Increasing urban populations within the Selwyn district also require clean, safe drinking water.
The Selwyn/Waikirikiri river is valued by local communities as a place for fishing, swimming and recreational use. Over the last few years there has been a lot of public concern because of algal blooms and extended periods of very low flow. At the bottom of the Selwyn catchment lies Te Waihora/Lake Ellesmere, the fifth largest lake in New Zealand. Despite Te Waihora having a high eutrophic level due to the last 150 years of land management practices, it continues to support significant commercial eel and flounder fisheries, plus biodiversity and recreational values. Te Waihora/Lake Ellesmere is increasingly vulnerable to pressures from the catchment above. Finally, the impact of climate change on fresh water in the district is not very well understood.
The S4/Selwyn Super Science Site is an aspirational concept with the aim to trial the Selwyn-Waihora catchment as a teaching and research hub. The project acts as a conceptual framework to recognise and celebrate existing teaching and research activities. The catchment features as a teaching site in the following WCFM undergraduate and postgraduate courses.
- WATR 201 Freshwater Resources
- WATR 202 Water on Land: Quality and Quantity
- WATR 203 Freshwater Science Field Skills
- WATR 401/601 Advanced Water Resources
- WATR 402/602 Water Quality and Quantity Assessment
If resources allow, the S4 Project identifies opportunities to concentrate new research investigations into the catchment. Current projects are listed below

The WCFM coordinates the Te Waihora/Lake Ellesmere Integrated Monitoring Strategy. Te Waihora/Lake Ellesmere is New Zealand’s 5th largest lake and largest coastal lagoon. 40 generations of human history can be traced to the lake. It is a significant eel fishery, an internationally recognised wetland, and home to 167 species of bird. The strategy is a three year project (August 2017- August 2020), which aims to centralise existing monitoring data relevent to Te Waihora/Lake Ellesmere, plus fill key gaps in monitoring data. The strategy was developed by Prof. Ken Hughey (Lincoln University) and is a living document which is reviewed on an as-needed basis.
