Pedirka Basin Potentiometric Surface Contour 20m - PED

## **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\nDensity corrected groundwater elevation contours for the Permian aquifers in the Pedirka Basin displayed at a 20 m interval.\n\n## **Purpose** \n\nTo describe the regional groundwater flow pattern within the Pedirka Basin.\n\n## **Dataset History** \n\nGroundwater flow contours are based on density corrected water level measurements from groundwater wells and pressure readings from drill stem tests in exploration wells. Contours are reduced to relative Australian Height Datum (mAHD). Due to data paucity the line work was developed using digitised hand drawn contours. The potentiometric surface is published in the Pedirka Basin Hydrogeological Map (Sampson L, Wohling D, Fulton S, Jensen-Schmidt B and Keppel M, 2014, South Australia and Northern Territory Pedirka Basin Hydrogeological Map - Part 1 & Part 2.

**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），本文档按原始提交内容呈现。

佩迪尔卡盆地二叠纪含水层（Permian aquifers）的密度校正地下水水位等值线，等值线间距为20米。

**数据集用途**

用于描述佩迪尔卡盆地内的区域地下水流动模式。

**数据集历史**

地下水流动等值线基于地下水井的密度校正水位测量数据，以及勘探井中钻杆测试（drill stem tests）获得的压力读数。等值线已归算至相对澳大利亚高程基准（mAHD）。由于数据匮乏，本次等值线图层通过数字化手绘等值线生成。该测压水面已刊载于《佩迪尔卡盆地水文地质图》（Sampson L、Wohling D、Fulton S、Jensen-Schmidt B与Keppel M，2014年，《南澳大利亚与北领地佩迪尔卡盆地水文地质图——第1部分&第2部分》，南澳大利亚政府环境、水与自然资源部）。
