Climate change impacts on erosion and sediment loads in New Zealand

This info sheet is for:

Those interested in the future implications of climate change on erosion and sediment loads in New Zealand. Policymakers, catchment managers, farmers and landowners who rely on data for informed decision making.

This research explores how climate change will impact sediment loads in our rivers through modelling changes to surficial erosion, mass movement and streambank erosion. The framework takes the impact of divergent future trajectories for mean annual rainfall (MAR), storm magnitude-frequency, and mean annual flood (MAF) to be expressed in future sediment loads through distinct changes in surficial, mass movement, and streambank erosion.
