This file provides the data for 423,352 stream segments within the (pour point) catchments analysed in this study. The data includes baseline sediment loads and loads after NZFARM modelling to optimise location of ESC mitigations. It includes modelling of “Glacial Mountain” source-of-flow segments which have naturally high sediment loads, but have been included to maintain a contiguous stream network for sediment routing purposes. The file contains both stream segments which already meet sediment bottom line targets and those that required a reduction in sediment load to achieve bottom line.
This file shows the location of mitigatable land where mitigations were applied in NZFARM modelling. The data contains an ID field for the mitigatable land parcel, the area of the mitigatable land parcel, and the proportion of the land parcel which the NZFARM modelling applied a Whole Farm Plan or Afforestation to.
