Great Artesian Basin groundwater recharge estimates

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nGroundwater recharge estimates within the intake beds of the Cadna-owie - Hooray and equivalents aquifer and the Hutton Sandstone aquifer in the Great Artesian Basin. Recharge estimates are given in mm/year and are calculated using chloride mass balance method. Grid cell size (X, Y) = 0.015 DD, 0.015 DD. This GIS data set was produced for the Great Artesian Basin Water Resource Assessment and used in Figures 7.9 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin. A technical report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment. CSIRO Water for a Healthy Country Flagship, Australia. This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 76932. For further information, contact: CSIRO Land and Water Waite Road Urrbrae SA 5064\n\n## **Dataset History** \n\nSOURCES: Chloride deposition from rainfall data came from 'Australian 0.05 degree gridded chloride deposition', Geoscience Australia dataset (available from http://www.ga.gov.au, catalogue number 71620). For the western margin of the GAB, recharge estimates are from Love et. al. (2013). For the eastern margin, groundwater chloride concentrations were obtained from recharge studies by Kellett et al. (2003) and Habermehl et al. (2009). No-data value is -9999 REFERENCES: 1. Love et al.

**摘要**

本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），本文档按原始提交版本呈现。

本数据集涵盖大自流盆地（Great Artesian Basin）中Cadna-owie-Hooray含水层及其等效含水层与赫顿砂岩含水层（Hutton Sandstone aquifer）补给区的地下水补给量估算值。补给量估算值以毫米/年（mm/year）为单位，采用氯离子质量平衡法计算得到。网格单元尺寸（X、Y方向）均为0.015 DD。

本地理信息系统（GIS）数据集为大自流盆地水资源评估项目制作，被用于Ransley TR与Smerdon BD主编（2012年）的《大自流盆地水文地层学、水文地质与系统概念模型（Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin）》一书中的图7.9。该报告为澳大利亚联邦科学与工业研究组织（CSIRO）大自流盆地水资源评估项目提交给澳大利亚政府的技术报告，由澳大利亚CSIRO健康国家水资源旗舰项目（CSIRO Water for a Healthy Country Flagship）出品。

本数据集及相关元数据可通过目录编号76932从www.ga.gov.au获取。如需进一步信息，请联系：CSIRO土地与水资源部，地址：澳大利亚南澳州厄布拉伊市韦特路5064号。

**数据集历史**

数据来源：降雨氯离子沉降数据取自澳大利亚地球科学局（Geoscience Australia）发布的《澳大利亚0.05度网格化氯离子沉降》数据集（可从http://www.ga.gov.au获取，目录编号71620）。针对大自流盆地西缘的补给量估算值取自Love等人（2013年）的研究成果。针对大自流盆地东缘的地下水氯离子浓度数据取自Kellett等人（2003年）与Habermehl等人（2009年）的补给量研究。无数据值为-9999。
