February 2017Sediment is an important contaminant in New Zealand freshwaters. This report presents the development of an analytical framework to empirically relate various key instream measures of sediment to catchment sediment loads. Read more -
February 2017This report has been produced to test potential consequences of setting freshwater objectives for hydro scheme operations. Modelling was undertaken of a selection of various scenarios involving an increase in minimum flows in selected rivers to assess the impact of draft proposals to amend the NPS Freshwater Management on the New Zealand electricity system.
