Abstract: Dato_Procesados_CodigoObra.csv Daily time series by well (obra). Each record corresponds to one date and one well identified by its CodigoObra, with its administrative location (Region, Provincia, Comuna), its hydrogeological context (Acuifero, Shac, for Common Use Hydrogeological Sector), and its coordinates (Latitud, Longitud). It includes the pumping rate (Caudal (l/s)) and the water level (Nivel Freático (m)) in their original form, together with their processed versions: a trend component (Caudal_TL, Nivel_Freatico_TL) and a LOWESS smoothing (Caudal_Lowess, Nivel_Freatico_Lowess). For each variable, the trend analysis results are reported: Mann-Kendall tau statistic and p-value (MK_Tau, MK_pvalue), trend direction (MK_Tendencia), annual Sen slope (SenSlope_Anual), and the date and significance of the detected changepoint (Changepoint_Fecha, Changepoint_Sig). The _origen column records the source file each data point comes from. Tabla_MK_CodigosObra_Seleccionadas.csv Summary table with one row per selected well. For pumping rate and water level, it consolidates the Mann-Kendall test results (MK_Tau, MK_pvalue, MK_Tendencia) and the annual Sen slope (SenSlope_Anual), along with each well's region and aquifer. It corresponds to the subset of wells used in the article's comparative analysis.
