Modelling the impact of freshwater mitigation scenarios: results for the Ruamahanga catchment

Publication date:  September 2019
Publication reference number:  CR 377

This report sets out the results of a modelling exercise that assessed the potential economic impacts of meeting a range of contaminant loads and attributes states for nitrogen, phosphorus, and sediment in the Ruamahanga catchment in Wairarapa. The integrated model estimates a calibrated baseline (business as usual) and compares results of contaminant reductions from more than 50 mitigation scenarios to this baseline.
