Measuring Water Quality
Andriy Medvediuk - 123RF
How will we know if the actions people all over Aotearoa are taking to improve the health of our freshwater are working? Our research is striving to fill data gaps and build knowledge about how to measure and model water quality.

Predicting improved optical water quality in rivers resulting from soil conservation actions on land
Soil conservation not only conserves soil but it improves the water clarity of water in rivers. This improvement may be estimated by the methods shown…

Assessing the Yield and Load of Contaminants with Stream Order: Would Policy Requiring Livestock to Be Fenced Out of High-Order Streams Decrease Catchment Contaminant Loads?
This paper won the JEQ Best Paper Award 2019. Concentration and flow data for 1998 to 2009 were used to calculate catchment load and yields…

Anthropogenic increases of catchment nitrogen and phosphorus loads in New Zealand
Spatial regression models were used to predict yields of nitrogen (N) and phosphorus (P) discharged from catchments throughout New Zealand. The models were derived using…
