Download Modelling the effect of stock exclusion on E. coli in rivers and streams - National application

MPI commissioned NIWA, in partnership with AgResearch Ltd, to develop and run a national model for predicting the impacts of fencing for stock exclusion on fresh water quality as indicated by annual median and 95th percentile E. coli concentrations. This report documents the development of the national E. coli model including data sources, model calibration and application as well as sources of error and uncertainty.
