Abstract

Considerable work has been carried out both in Australia and overseas on the spatial variations in recharge and discharge. This work usually relates point measurements and modelled recharge to spatial units such as land management units or soil units. There is also a considerable literature on the use of remote sensing and geographic information systems in mapping hydrological features including recharge and discharge zones. This report brings together much of this work. It describes the various data that can be used at a national or finer scale as inputs to GIS-based models for spatial distribution of recharge and discharge characteristics. These include remotely sensed satellite imagery and common remote sensing algorithms; digital elevation models; geophysical data (airborne electromagnetics, gamma-ray radiometrics); water table surface elevation mapping; climate; soil, regolith and geology; and vegetation and land cover. This report also describes various mapping frameworks that could be adapted to provide a spatial context for mapping the distribution of recharge-discharge characteristics including Atlas of Australian Soils, Hydrogeomorphic Units, Hydrogeological Landscapes and Groundwater Flow Systems. It is recommended that remote sensing and GIS methods be developed for mapping recharge and discharge zones usign a variety of data from a variety of sources. Each dataset needs to be characterised in terms of its resolution, availability and ease of use. When combined with companion reports that review recharge and discharge estimation studies in Australia, these reports will provide the basis for the subsequent phase of the project, aimed at demonstrating methodologies for recharge/discharge estimation in data poor areas.
