CLM - Hydraulic conductivity QLD

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nThis dataset contains the hydraulic conductivity and transmissivity data for the Queensland part of the Clarence-Moreton Basin. The data were organized by geological formations. The data were sourced from the Queensland state groundwater databases. Most records in the pumping test database do not have a hydraulic conductivity entry. The hydraulic conductivity was derived from the pumping test data by a two-step method to support the groundwater modelling: (i) transmissivity was estimated from the original test readings using the TGUESS approach; and (ii) hydraulic conductivity was calculated based on the estimated transmissivity and the screen information. The estimated hydraulic conductivity was mainly available for the alluvium and volcanics and varies in a range of six orders of magnitude.\n\n## **Dataset History** \n\nThis dataset was created through the following process:\n\n\n\n1. Filter the data using the spatial extent of the Clarence-Moreton Basin;\n\n2. Data quality check;\n\n3. Calculate transmissivity using the TGUESS approach;\n\n4. Compute hydraulic conductivity using the calculated transmissivity and the screen information in the state database;\n\n5. Aquifer assignment.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) CLM - Hydraulic conductivity QLD. Bioregional Assessment Derived Dataset.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多源数据集衍生而来，其源数据集信息已在本元数据声明的Lineage字段中注明，该衍生数据集的生成流程详见本元数据声明的History字段。

本数据集涵盖克拉伦斯-莫顿盆地（Clarence-Moreton Basin）昆士兰州段的导水率（hydraulic conductivity）与导水系数（transmissivity）数据，数据按地质地层进行整理，源自昆士兰州地下水数据库。多数抽水试验（pumping test）数据库记录未包含导水率条目，研究团队通过两步法从抽水试验数据中衍生出导水率以支撑地下水模拟：(i) 采用TGUESS方法从原始试验读数中估算导水系数；(ii) 基于估算得到的导水系数与滤水管信息计算导水率。估算得到的导水率主要分布于冲积层与火山岩中，数值跨度达六个数量级。

**数据集历史**

本数据集通过以下流程生成：

1. 基于克拉伦斯-莫顿盆地的空间范围对数据进行筛选；
2. 开展数据质量检查；
3. 采用TGUESS方法计算导水系数；
4. 基于计算得到的导水系数与州级数据库中的滤水管信息计算导水率；
5. 含水层赋值。
