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.
