Exciting news! Our journal article: "A Hydrochemically Guided Landscape Classification System for Modelling Spatial Variation in Multiple Water Quality Indices: Process-Attribute Mapping" has been accepted for publication in Science of the Total Environment. This paper presents the general method for Process Attribute Mapping and demonstrates its performance in an application to the Southland region. Performance measures included cross-validated R2 values of between 0.85 – 0.95 for median total nitrogen, total oxidised nitrogen, total phosphorus, and dissolved reactive phosphorus for regional surface waters. Total suspended sediment and E. coli returned cross-validated R2 of 0.73 and 0.72 for median values. This work was completed under the Physiographic Environments of New Zealand project, which is co-funded by Our Land and Water National Science Challenge and several regional councils.

Some more exciting news - Our work with Living Water - DOC & Fonterra looking in to the placement of Peak Runoff Control options in the Waituna Catchment, has been featured in this months Rivers Group newsletter.

Land and Water Science we were excited to learn that we are one of three finalists in the Environment and Sustainability category for the New Zealand Spatial Excellence Awards!

The submitted project was on the High-resolution physiographic mapping of the Waituna Catchment that we did for Living Water. We are looking forward to the finalists awards in Wellington on the 17th of October.
