Hunter surface water quality analysis

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the Hunter Surface Water Data v2 dataset. The source dataset is 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\nDaily variation  of electrical conductivity (EC) at Denman, Glennies Creek and Singleton stream gauges on the Hunter River from 1993 to 2013 for the Hunter subregion. The dataset is an excel spreadsheet containing daily EC data extracted from Streamflow gauging data supplied by NSW Office of Water. It also contains the charts of time series variations in EC at the three locations which appear in the context report.\n\n## **Dataset History** \n\nDaily variation  of electrical conductivity (EC) at Denman on the Hunter River from 1993 to 2013 for the Hunter subregion. Data were extracted from water quality info for selected gauges supplied by the NSW Office of Water. Data are plotted in graphs for the selected gauges in the context report.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) Hunter surface water quality analysis.

## **摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）从亨特地表水数据v2（Hunter Surface Water Data v2）数据集衍生而来。源数据集的相关信息可在本元数据声明的谱系（Lineage）字段中查询，本衍生数据集的生成流程已在本元数据声明的历史（History）字段中详细说明。

本数据集涵盖1993年至2013年亨特次区域内，亨特河上登曼（Denman）、格伦尼斯溪（Glennies Creek）及辛格尔顿（Singleton）三处水文测站的电导率（electrical conductivity, EC）日变化数据。数据集为Excel电子表格，包含从新南威尔士州水务局（NSW Office of Water）提供的流量监测数据中提取的日度电导率数据；此外还收录了三处测站电导率时间序列变化的图表，该图表已在背景报告中呈现。

## **数据集历史**
本数据集涵盖1993年至2013年亨特次区域内亨特河登曼测站的电导率日变化数据。数据从新南威尔士州水务局提供的选定测站水质信息中提取，相关测站的电导率时间序列变化图表已在背景报告中绘制完成。
