Northern Inland Catchments - Hydrogeology Aquifer Boundaries

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

A set of datasets outlining the various Hydrogeological boundaries. These include:

QLD Alluvium - Top of lower alluvial aquifer boundary of the Lower Balonne area, Southern Queensland

Discharge Zone - Potential upward discharge zone in the Condamine alluvium

Northern Namoi Paleochannel - the Northern Namoi Paleochannel is depicted as a groundwater drain in the Narrabri Formation. The drain is generated by the large amount of groundwater pumping for irrigation mostly from the Gunnedah Formation over the Lower Namoi Valley but especially in the palaeochannel.

NSW Alluvium - Hydrogeologic alluvium features of Northern NSW. Shows areas where a) head in Quaternary Alluvial aquifer is higher than the Aquifer; b) Head in Quaternary alluvial aquifer is lower; c) Quaternary alluvial aquifer is absent or unsaturated; d) Absent

St George Lower Alluvium Aquifer - Top of lower alluvial aquifer boundary of the Lower Balonne area, Southern Queensland.
