To improve the pastoral land cover/use areas, we obtained data developed from the research project Quantifying contaminant losses to water from pastoral land uses in New Zealand III. What could be achieved by 2035? This data contained updated information of the locations of pastoral land use (sheep and beef/dairy) as well as the maximum possible mitigation improvements associated with these lands.

The E. coli model in the Scenario Builder for Rivers WebApp was based on the report Parameters for simple empirical catchment water quality models for simulating Escherichia coli in New Zealand rivers.
