Summary
The aim of the project was to report the extent and impacts of dryland salinity based on the best readily available data. The agreed data elements to be analysed nationally were groundwater levels and trends from monitored bores. The approach to be used by all the States was based on the HARSD (Hydrogeomorphic Analysis of Regional Spatial Data) method (Salama et al. 1996a), which is a suite of procedures used for landscape classification, groundwater level mapping and flow net modelling. This method was meant to be carried out in a consistent and repeatable manner across all catchments.
The south-eastern half of Queensland was delineated for the study and broken into six regions to aid in analysis. Regions were grouped from a number of individual catchments. These regions were chosen due information availability, where existing knowledge of dryland salinity outbreaks were known, budget constraints and the fact that this was a desktop study.
