About this report
This report was commissioned by the Technical Leaders Group for the Healthy Rivers Wai Ora Project Report No. HR/TLG/2016-2017/2.2A
The report describes two nutrient load models that were developed to provide input data to an economic mode. The latter evaluates the costs associated with mitigating farm practices to reduce nutrient loads. This report also describes model input and calibration data, the methods used to determine median annual nutrient concentrations and mean annual loads from monthly water quality sampling data, and sources of model uncertainty.
