You can use the Scenario Builder for Rivers WebApp to:
visualise the current state of water quality (E. coli, nitrogen and phosphorus concentrations and estimated periphyton biomass) at over 900 river monitoring sites across New Zealand.
assess the “reference” water quality conditions at the site
see the composition of land use in the catchment and the estimated relative contribution of different land uses in the catchment to contaminant loads
model catchment management scenarios of land mitigation or land use change (or combinations of both) to predict how reducing contaminant losses from existing land use and/or changing land use within the catchment will affect the water quality in the river.
