(eds) 2013 (Figure 5.14 Present-day corrected potentiometric surface of the J aquifer for the variable temperature assumption) which was generated from a surface grid that is calculated from temperature and density corrected waterbore head measurements obtained between 2000 and 2010.

## **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项目（Bioregional Assessment Programme），并按原始提供形式呈现于此。

Cadna-Owie-Hooray及等效含水层（Aquifer）的经温度和密度校正的复合测压水面（potentiometric surface）等高线与推断的区域地下水流向包含两个独立数据层：A：测压水面等高线；B：区域地下水流向箭头——推断。该复合测压水面等高线基于Ransley & Smerdon 2013（图7.4——现代（约2010年）测压水面）和Love等人（编）2013（图5.14——变温假设下J含水层的现代校正测压水面）修改而成，后者由2000-2010年期间获取的经温度和密度校正的水井水头测量值计算得到的表面网格生成。区域地下水流向被推断为沿垂直于地下水水头等势线的水力梯度向下流动。本数据集及相关元数据可通过目录号81688从www.ga.gov.au获取。参考文献：Love等人（编）2013，《大自流盆地（Great Artesian Basin）的水资源分配与泉域维护》第二卷：西部大自流盆地的地下水补给、水动力学与水化学，澳大利亚国家水委员会，堪培拉；Ransley TR与Smerdon BD（编）（2012）《大自流盆地的水文地层学、水文地质学与系统概念化》，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，CSIRO健康国家水旗舰项目，澳大利亚；Ransley, T.等，2014，《大自流盆地水文地质图集》，澳大利亚地质科学局（Geoscience Australia），堪培拉。[可通过目录号79790从www.ga.gov.au获取]

## **目的**

可视化Cadna-owie-Hooray及等效含水层（Aquifer）内地下水压力的空间变化。

## **数据集历史**

源数据：数据来源于以下多种渠道：1. Ransley & Smerdon 2013（图7.4——现代（约2010年）测压水面）；2. Love等人（编）2013（图5.14——变温假设下J含水层的现代校正测压水面）。方法：测压水面等高线——将数据源1和2的等高线导入ArcGIS；在大自流盆地（GAB）的南澳大利亚州/北领地（SA/NT）区域内，删除数据源1的等高线并替换为数据源2的等高线；沿两个数据源的边界对测压水面等高线进行手动修改，以实现数据集的边缘匹配。推断区域地下水流向——通过在ArcGIS中手动绘制垂直于测压水面等高线的箭头，生成推断的流向箭头。质量保证与质量控制（QAQC）：数据经过QAQC验证过程，以捕捉并修复属性和几何误差。软件：所有修改/编辑及地理处理均使用ESRI ArcGIS 10软件完成。
