Suspended Sediment loads modelled using SedNetNZ.
The dataset - What is it?
This data pertains exclusively to the Wairoa River and was created to simulate erosion and suspended sediment levels within the Wairoa catchment under various mitigation scenarios. It evaluates the necessary reductions needed to comply with the National Policy Statement for Freshwater Management 2020 (NPS-FM) considering both present-day and future climate conditions.
Why it's important
The information is important because it allows people to understand suspended sediment loads in the Wairoa catchment are the impacts mitigations has on these loads.

Caveats
Refer to the two accompanying reports for detailed information on model assumptions and limitations. Key assumptions relate to the representation of erosion processes, climate change projections and their impacts on erosion rates and sediment loads, as well as the effectiveness of the erosion mitigations represented in the best-efforts scenario.
