Sediment reduction and mitigation principles – a review of New Zealand literature

Report: TR 2023/28

Authors: John Drewry, Chris Phillips, Scott Graham (Manaaki Whenua – Landcare Research)

Waikato Regional Council (WRC) is producing a strategic document on erosion from farmland and other sources in the Waikato region.

WRC contracted Manaaki Whenua – Landcare Research to undertake a literature review to provide information on erosion and sediment, and its control.

This information will help WRC explain the impact of erosion and sedimentation on communities, and the consequent loss of natural capital and ecosystem services. It will also help to communicate the sediment story for different farming systems and civil defence issues.

The objective of this report was to conduct a general review of the New Zealand literature on erosion and sediment reduction, with a focus on literature relevant to the Waikato region.
