Surface water groundwater interactions of stream reaches in the Murray Darling Basin within the network of the AWRA R river systems model

This dataset contains a classification of the stream reaches in the Murray Darling Basin by their proportion of bores predicting losing or gaining conditions within the network of the AWRA-R river systems model. The classification is applied on an annual basis from 1/6/1970 to 31/5/2019 (49 years). The dataset was created for the purpose of identifying which reaches are potentially losing stream water to groundwater and how these conditions have changed through time. The dataset contains a figure displaying a summary of the data (summary since 2000.png), a shapefile containing the results of the summary (SW-GW_int_summary_2000_2019.shp) and a csv file for each year with the number and proportion of bores predicting losing and gaining conditions (MDB_gain_lose_YYYY_YYYY.csv). The csv files contain a field with the reach name (ID_updated) that can be used to link to the shapefile for viewing the data. There are columns for the number of bores predicting losing conditions (no_losing), gaining conditions (no_gaining) and those where the measurements were too close to classify (no_unsure). There is also a column for the total number of bores with water level observations within that reach for that year (cnt). The number of bores predicting a condition is also normalised as a proportion of the total number of bores within the reach (p_losing, p_unsure, and p_gaining). The shapefile contains the river network from the AWRA-R river model, the reaches within this model are identified by ID_updated and Reach_ID. The downstream gauge for each reach is identified by the fields for the gauge ID (GaugeID) and gauge name (GaugeName). The data within the shapefile is a summary of the proportion losing conditions for the 19 years from 2000/2001 to 2018/2019. Each reach is summarised by the mean proportion (p) of bores predicting losing conditions: Always losing (p = 1), mostly losing (0.67

本数据集包含墨累-达令盆地（Murray Darling Basin）内河段的分类结果，分类依据为AWRA-R河系模型网络中预测失水或得水状态的钻孔比例。分类以年度为单位，时间跨度为1970年6月1日至2019年5月31日（共49年）。创建本数据集旨在识别哪些河段可能向地下水失水，以及这些状态随时间的变化规律。数据集包含一份数据摘要图（summary since 2000.png）、一份包含摘要结果的形状文件（SW-GW_int_summary_2000_2019.shp），以及每年一份的CSV文件（MDB_gain_lose_YYYY_YYYY.csv）——该CSV文件记录了预测失水和得水状态的钻孔数量及比例。CSV文件包含一个河段名称字段（ID_updated），可用于关联形状文件以查看数据。文件中设有列记录预测失水状态的钻孔数（no_losing）、得水状态的钻孔数（no_gaining），以及测量值过于接近而无法分类的钻孔数（no_unsure）。此外，还有一列记录该河段当年有水位观测数据的钻孔总数（cnt）。预测各状态的钻孔数还被归一化为河段内钻孔总数的比例（p_losing、p_unsure和p_gaining）。形状文件包含AWRA-R河模型的河网数据，模型内的河段由ID_updated和Reach_ID标识。每个河段的下游水文站由水文站ID（GaugeID）和水文站名称（GaugeName）字段标识。形状文件中的数据是2000/2001至2018/2019这19年间失水比例的摘要。每个河段通过预测失水状态的钻孔平均比例（p）进行汇总：始终失水（p=1）、主要失水（0.67
