HUN AWRA-L simulation nodes_v01

## **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 is a subset for the Hunter of a shapefile that shows geographical locations and other characteristics (see below) of streamflow gauging stations and also includes additional simulation nodes. \n\nThere are 3 files that have been extracted from the Hydstra database to aid in identifying sites in each bioregion and the type of data collected from each.\n\n\n\nthe 3 files are:\n\nSite - lists all sites available in Hydstra from data providers. The data provider is listed in the \\#Station as _xxx. For example, sites in NSW are _77, QLD are _66.\n\nSome sites do not have locational information and will not be able to be plotted. \n\nPeriod - the period table lists all the variables that are recorded at each site and the period of record.\n\nVariable - the variable table shows variable codes and names which can be linked to the period table.\n\n## **Purpose** \n\nLocations are used as pour points in roder to define reach areas for Macquaire-Tuggerrah Lake basin where only AWRA-L modelling is taken.\n\n## **Dataset History** \n\nSubset of data for the Hunter that was extracted from the Bureau's hydstra system and includes all gauges where data has been received from the lead water agency of each jurisdiction. Simulation nodes were added in locations in which the model will provide simulated streamflow.\n\n\n\nThere are 3 files that have been extracted from the Hydstra database to aid in identifying sites in each bioregion and the type of data collected from each.\n\n\n\nthe 3 files are:\n\nSite - lists all sites available in Hydstra from data providers.

## **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所得。本元数据声明的谱系（Lineage）字段中已标注所有源数据集，而衍生本数据集所采用的处理流程则记载于本元数据声明的历史（History）字段中。

本数据集为亨特（Hunter）区域的子集，源自展示流量监测站地理位置及其他特征（详见下文）的Shapefile文件，同时包含额外的模拟节点。

本次共从Hydstra数据库中提取3个文件，用于辅助识别各生物区域内的监测站点以及各站点所采集的数据类型。

三个文件详情如下：
1. **站点表（Site）**：收录了Hydstra数据库中来自各数据提供方的全部站点。数据提供方信息以`_xxx`格式标注于`#Station`字段中，例如新南威尔士州（NSW）的站点标注为`_77`，昆士兰州（QLD）的站点标注为`_66`。
部分站点未包含位置信息，无法进行绘图展示。
2. **时段表（Period）**：列出了各站点所记录的全部变量以及数据记录时段。
3. **变量表（Variable）**：展示了变量代码与变量名称，可与时段表进行关联匹配。

## **目的**

本数据集的监测站点位置被用作汇点（pour point），用于划定仅开展AWRA-L建模的麦夸里-塔格拉湖（Macquaire-Tuggerrah Lake）流域的河段范围。

## **数据集历史**

本数据集为亨特区域的数据子集，提取自澳大利亚水文局的Hydstra系统，包含所有从各辖区主管水务机构获取了有效数据的流量监测站。同时在模型将提供模拟流量的位置处新增了模拟节点。
