Streamflow data and locations for selected gauges in the Hunter subregion

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from data supplied by the Bureau of Meteorology. 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\nStreamflow timeseries data and gauge locations for selected gauges in the Hunter subregion. This dataset was created to establish a unified streamflow dataset, based on the 24 July 2014 dataset provided by the BoM.\n\n## **Purpose** \n\nThe data was used for preparing contextual statement, calibrating and validating surface water modelling, and establishing surface hydrological response variables.\n\n## **Dataset History** \n\nThe data was created using the original 24 July 2014 streamflow data. The process steps are as follows\n\n1.\tTo move one day backward to match precipitation data since the original 9:00am data is for the period of the current 10:00 am to next 9:00 am\n\n2.\tTo identify gauge stuck issue\n\n3.\tTo identify data linear interpolation issue\n\n4.\tTo regard the issue data as missing data\n\n5.\tTo generate streamflow data with the unified quality codes: (1: Good; 2: Fair; 3: Poor; 4: Unverified; 5: Non-conforming; 6: Missing)\n\n6.\tTo separate daily streamflow into baseflow and quick flow using the standard filtering method (Lyne and Hollick (1979)). \n\nThe data was created in MATLAB using scripts and functions.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) Streamflow data and locations for selected gauges in the Hunter subregion.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于澳大利亚气象局（Bureau of Meteorology，简称BoM）提供的数据衍生所得。本元数据声明的Lineage字段标注了源数据集的来源，而该衍生数据集的制作流程详见本元数据声明的History字段。

本数据集涵盖亨特次区域选定水文站的径流时序数据与测站位置信息，其构建以澳大利亚气象局2014年7月24日提供的原始数据集为基础，旨在形成一套统一的径流数据集。

**用途**
本数据集可用于编制背景说明文档、率定与验证地表水模型，以及构建地表水文响应变量。

**数据集处理历史**
本数据集基于2014年7月24日的原始径流数据制作完成，具体处理步骤如下：
1. 将数据整体后移一日，以匹配降水数据——因原始的当日9:00时刻数据对应的时段为当日10:00至次日9:00。
2. 识别水文测站数据卡死异常。
3. 识别数据线性插值异常。
4. 将存在异常的数据视为缺失值处理。
5. 生成带有统一质量编码的径流数据：(1: 优良; 2: 合格; 3: 较差; 4: 未验证; 5: 不合格; 6: 缺失)。
6. 采用标准滤波法（Lyne和Hollick，1979）将日径流序列分解为基流与快速流。

本数据集通过MATLAB脚本与函数编写生成。
