Raw And Processed Hydro-Meteorological Variables Of Jucar River Basin For Feature Selection

The dataset Processed data – input WQEISS.csv was employed for the input variable selection step in Zaniolo et al., 2018. It includes monthly values of 28 hydro-meteorological variables and indexes of Jucar river basin, Spain, for the period 1986-2000, namely: 2 temporal features: day and month of the year; 12 inputs to the Jucar State Index: average monthly storage and groundwater levels, average three months river runoff, and cumulated areal precipitation over 12 months; 8 additional observed variables in the basin: three months average outflows from, and inflows to, the main reservoirs, and mean monthly areal temperatures; 6 traditional drought indicators: Standardized Precipitation Index (SPI) and Standardized Precipitation and Evaporation Index (SPEI). SPI and SPEI indicators are computed on mean monthly data over the entire basin for 3, 6, and 12 months time aggregations. The last column of the dataset reports the target variable, i.e., the monthly nominal shortage of water conveyed to the irrigation districts simulated via AQUATOOL model. For further details on the dataset please consult Zaniolo et al., 2018, or the dedicated website http://www.nrm.deib.polimi.it/?page_id=2438 The unprocessed data used to compute indices and temporal cumulations in Processed data – input WQEISS.csv are reported in table Raw Data.csv. Public observations of rainfall, streamflows and storage levels come from the SAIH (Hydrological Automatic Information System) of the CHJ (Jucar Hydrological Confederation). Users can directly download data for the last 12 months on the dedicated webpage http://saih.chj.es/chj/saih/?f while previous data records are provided for free by CHJ upon request. Observations from piezometers are downloadable from the Piezometric Network Information section section of the CHJ https://www.chj.es/es-es/medioambiente/redescontrol/Paginas/Piezometr%C3%ADa.aspx.本数据集采用预处理后的数据文件WQEISS.csv，用于Zaniolo等（2018）研究中的输入变量筛选环节。该数据集涵盖1986年至2000年西班牙胡卡尔（Jucar）流域的28项水文气象变量月度值及相关指数，具体包括： 1. 2项时间特征：年度日期与月份； 2. 胡卡尔国家指数（Jucar State Index）的12项输入项：月度平均蓄水量与地下水位、3个月平均河道径流量，以及全流域12个月累积面降水量； 3. 流域内额外8项实测变量：主要水库的3个月平均出流量与入流量，以及月度面平均气温； 4. 6项传统干旱指标：标准化降水指数（Standardized Precipitation Index, SPI）与标准化降水蒸发指数（Standardized Precipitation and Evaporation Index, SPEI）。SPI与SPEI指标基于全流域月度平均数据，针对3、6、12个月的时间尺度进行计算。 数据集的最后一列为目标变量，即通过AQUATOOL模型模拟的、输送至灌区的月度名义缺水水量。如需了解该数据集的更多细节，请查阅Zaniolo等（2018）的研究，或访问专用网站：http://www.nrm.deib.polimi.it/?page_id=2438。 用于生成WQEISS.csv预处理数据中各类指数与时间累积量的原始数据，已整理至Raw Data.csv表格中。降雨、河道流量与蓄水位的公开观测数据，来自胡卡尔水文联合会（Jucar Hydrological Confederation, CHJ）旗下的水文自动信息系统（Hydrological Automatic Information System, SAIH）。用户可通过专用网页http://saih.chj.es/chj/saih/?f直接下载近12个月的观测数据；更早的历史数据可向CHJ申请免费获取。测压管的观测数据可从CHJ官网的「测压网信息板块」下载：https://www.chj.es/es-es/medioambiente/redescontrol/Paginas/Piezometr%C3%ADa.aspx。
