HUN AWRA-R simulation nodes v01

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple datasets. 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\nThe dataset consists of an excel spreadsheet and shapefile representing the locations of simulation nodes used in the AWRA-R model. Some of the nodes correspond to gauging station locations or dam locations whereas other locations represent river confluences or catchment outlets which have no gauging. These are marked as "Dummy".\n\n## **Purpose** \n\nLocations are used as pour points in oder to define reach areas for river system modelling.\n\n## **Dataset History** \n\nSubset of data for the Hunter that was extracted from the Bureau of Meteorology'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 on. These data were used to determine the simulation node locations where model outputs were generated. \n\n\n\nThe 3 files contained within the source dataset used for this determination 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\n\nRelevant location information and other data were extracted to construct the spreadsheet and shapefile within this dataset.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) HUN AWRA-R simulation nodes v01.

## **摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多份源数据集衍生而来。本元数据声明中的谱系（Lineage）字段已标注源数据集信息，而本衍生数据集的制作流程则详见元数据声明中的历史（History）字段。

本数据集包含一份Excel电子表格与一个形状文件（shapefile），用于呈现AWRA-R模型所用模拟节点的位置信息。其中部分节点对应水文测站或水坝的位置，其余节点则代表无水文监测的河流汇流点或流域出口，此类节点被标记为“Dummy”。

## **用途**
此类位置被用作河网建模中的汇点（pour points），以划定河段范围。

## **数据集历史**
本数据集的亨特（Hunter）区域数据子集从澳大利亚气象局（Bureau of Meteorology）的Hydstra系统中提取，涵盖了从各辖区主管水务机构获取数据的全部水文测站。随后在模型可生成模拟径流的位置添加了模拟节点。

从Hydstra数据库中提取了3份文件，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。此类数据被用于确定生成模型输出结果的模拟节点位置。

用于确定模拟节点位置的源数据集包含以下3份文件：
1. 站点表（Site）：收录了Hydstra系统中所有数据提供商提供的监测站点。数据提供商信息将在`#Station`字段中以`_xxx`的形式标注，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）：列出了各监测站点所记录的全部变量，以及各变量的观测时段。
3. 变量表（Variable）：展示了可与时段表关联的变量代码与变量名称。

研究人员提取相关位置信息与其他数据，构建了本数据集内的电子表格与形状文件。
