HUN AWRA-R River Reaches Simulation 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\nHUN AWRA-R River Reaches Calibration v01 depicts the 'blue line' drainage network used in the river model AWRA-R. It includes information on stream length for each river reach defined in the river model node-link network. This dataset was derived by the Bioregional Assessment Programme from existing 'blue line data' obtained from DPI Water (Riverstyles Spatial Layer for New South Wales).\n\n## **Purpose** \n\nAWRA-R requires stream length of each stream within a river reach in AWRA-R in order to estimate model parameters related to in-stream losses and routing.\n\n## **Dataset History** \n\nHUN AWRA-R River Reaches Calibration v01 is created from a river map of NSW (described in the lineage) which is overlain and clipped by a river reach map from the Topo250k dataset, which in turn is defined by a subset of streamflow gauges. Only the river network between upstream and downstream gauges (may have multiple upstream gauges) are considered, the rest are manually selected and removed.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) HUN AWRA-R River Reaches Simulation v01.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）从多源数据集衍生得到。本元数据声明中的谱系（Lineage）字段已标注所用源数据集，而该衍生数据集的生成流程则在元数据声明的历史（History）字段中详述。

HUN AWRA-R 河道段校准版v01（HUN AWRA-R River Reaches Calibration v01）描绘了AWRA-R水文模型所采用的“蓝线”排水网络，包含该模型节点-链路（node-link）网络中定义的各河道段的河道长度信息。本数据集由生物区域评估计划从新南威尔士州DPI水资源部门（DPI Water）提供的现有“蓝线数据”（即新南威尔士州Riverstyles空间图层（Riverstyles Spatial Layer））衍生而来。

**用途**

AWRA-R水文模型需要各河道段内单条河道的长度信息，以估算与河道内损耗及河道汇流相关的模型参数。

**数据集历史**

HUN AWRA-R 河道段校准版v01基于新南威尔士州（NSW）河道图生成（相关信息详见谱系字段），该河道图经Topo250k数据集的河道段图层叠加与裁切得到；而Topo250k数据集的河道段图层由部分水文流量测站子集定义。本数据集仅保留上下游测站（可包含多个上游测站）之间的河道网络，其余河道网络均通过人工筛选移除。
