<br /><strong>Updated with new data on 13 Aug 2019</strong><br />
<p>This dataset includes three “packages” of information, each with multiple variables. The packages include:</p>
<ol>
<li>Load – results on mean annual suspended sediment load reported by REC 2 river reach scale for various model scenario variations. </li>
<li>Lakes – results on sediment inflow, outflow, and entrapment in lakes and reservoirs </li>
<li>Coastal – results on sediment inflows, trap efficiency, and sedimentation rates in coastal hydrosystems (estuaries)</li>
</ol>
<p>For further detail on the modelling methods and discussing results, see Hicks, M., Semademi-Davies, A., Haddadchi, A., Shankar, U., Plew, D. (2019) Updated sediment load estimator for New Zealand. NIWA Client Report No. 2018341CH, prepared for Ministry for the Environment. January 2019.

<p><em>Note that some portions of this dataset refine and update 2011 modelling on suspended sediment loads across New Zealand, whereas other components, especially the coastal package, report new modelling results.</em></p>

<p>This dataset reports modelled mean annual suspended sediment load reduction required to meet suspended sediment attribute bottom lines in the NPS-FM 2020. Results are reported for the REC 2 river reach scale as well as at the “catchment pourpoint average” scale. The dataset includes masks for the DoC estate as well as glacial mountain source of flow.</p>
<p></p>
<p>During policy development, the Ministry for the Environment tested suspended sediment load reductions required to meet various potential attribute bottom lines. The information from February 2020 reflects the bottom lines in the NPS-FM 2020. For further information on this specific dataset, see “Hicks and Shankar 2020. Contract 23184 Task: Sediment load reductions to meet visual clarity bottom lines”. This report is available on the Ministry for the Environment’s <a href="https://www.mfe.govt.nz/publications/fresh-water/further-analyses-of-fine-sediment-attributes-support-development-of-nps">publications website</a> where it is listed as Technical Report 6.</p>
