Great Artesian Basin - Alluvium Water level

This data set represents recent water level measurements as well as in the Quaternary alluvial aquifer in the Surat sub-basin and demarcates areas where water levels in the Quaternary alluvium are higher than the regional water table in the uppermost GAB aquifer, and areas where the GAB regional water table is coplanar with or higher than the water levels in the alluvium.There are two data layers,A: Alluvium water table elevation contours,B: Relationships between Alluvium water levels and GAB water table levels. This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 81674.REFERENCES:Ransley, T., Radke, B., Feitz, A., Kellett, J., Owens, R., Bell, J. and Stewart, G., 2015.

本数据集收录了苏拉特次盆地（Surat sub-basin）第四纪冲积含水层的近期地下水位监测数据，并划定了两类区域：一类为第四纪冲积层地下水位高于最上层大自流盆地（Great Artesian Basin, GAB）区域地下水位的区域，另一类为大自流盆地区域地下水位与冲积层地下水位齐平或更高的区域。
本数据集包含两个数据图层：
A. 冲积层地下水位高程等值线；
B. 冲积层地下水位与大自流盆地地下水位的对应关系。
本数据集及相关元数据可通过澳大利亚地质科学局（Geoscience Australia）官网www.ga.gov.au，以目录号81674获取。
