Description

This study is part of the Northern Territory Government Land and Water Suitability Program. It aims to improve the understanding of the area’s hydrogeology, including the extent and properties of the aquifers, the regional groundwater flow pattern, baseflow characteristics, identification of groundwater dependent ecosystems and a basic quantitative assessment of available groundwater. The ultimate purpose of the study is to combine knowledge of water availability with recent land unit mapping to identify areas suitable for various agricultural enterprises.,
