We are experiencing higher volumes of enquiries at the moment related to successive significant rainfall events in January and February. We are working hard to reply to these enquiries while at the same time planning and undertaking work to remove debris dams and blockages, and remediate impacted areas.

About this report

This report was commissioned by the Technical Leaders Group for the Healthy Rivers Wai Ora Project Report No. HR/TLG/2015-2016/1.2

The following aspects are covered in this report:

  • Brief summary of the method development and how the results can be applied to assist with estimates of sub-catchment attenuation and used to inform policy.
  • Figures for the overlay of the sub-catchment boundaries with the most appropriate maps of subsurface redox status. 
  • Summary of the likely degree of nitrate attenuation and a brief explanation will be provided for each sub-catchment in the Healthy Rivers project.
