“…Table 1 shows how many piezometers integrate every cluster for each sub-period. A layer corresponding to a rough spatial distribution of the groundwater extractions in the two different sub-periods [25,43] is also included in Figure 3 (in grey). To ease the interpretation, the raw piezometric time evolution for each visual cluster is shown in Figure 4 (clusters named V1.1, V1.2, V1.3 and V1.4 for the first sub-period) and Figure 5 (clusters named V2.1, V2.2, V2.3 and V2.4 for the second sub-period).…”

Groundwater resources are regularly the principal water supply in semiarid and arid climate areas. However, groundwater levels (GWL) in semiarid aquifers are suffering a general decrease because of anthropic exploitation of aquifers and the repercussions of climate change. Effective groundwater management strategies require a deep characterization of GWL fluctuations, in order to identify individual behaviors and triggering factors. In September 2019, the Guadalquivir River Basin Authority (CHG) declared that there was over-exploitation in three of the five groundwater bodies of the Almonte-Marismas aquifer, Southwest Spain. For that reason, it is critical to understand GWL dynamics in this aquifer before the new Spanish Water Resources Management Plans (2021–2027) are developed. The application of GWL series clustering in hydrogeology has grown over the past few years, as it is an extraordinary tool that promptly provides a GWL classification; each group can be related to different responses of a complex aquifer under any external change. In this work, GWL time series from 160 piezometers were analyzed for the period 1975 to 2016 and, after data pre-processing, 24 piezometers were selected for clustering with k-means (static) and time series (dynamic) clustering techniques. Six and seven groups (k) were chosen to apply k-means. Six characterized types of hydrodynamic behaviors were obtained with time series clustering (TSC). Number of clusters were related to diverse affections of water exploitation depending on soil uses and hydrogeological spatial distribution parameters. TSC enabled us to distinguish local areas with high hydrodynamic disturbance and to highlight a quantitative drop of GWL during the studied period.

“…This will affect ecological values in the future. Some effects seem to be already appearing (Manzano et al, 2009a;. A part of the ecotone and a series of lagoons are seriously damaged but other parts of the ecotone and many lagoons survive, although with deteriorating health.…”

“…Each piezometer has a 2 m screen in its base. Data from these new observation boreholes provided good understanding of vertical gradients, both in the recharge and in discharge zones of the aquifer, and also about the natural composition of the groundwater, the processes controlling it, the transit time of groundwater, the existence and extent of agricultural pollution and the relationship between the different wetland types and the aquifer (Iglesias 1999;Trick and Custodio, 2004;Lozano 2004;Lozano et al 2005;Manzano et al 2005Manzano et al , 2007Manzano et al , 2008Manzano et al , 2009Manzano et al , 2011Manzano et al , 2013Higueras 2014).…”

This chapter presents the monitoring and research of groundwater resources and natural recharge in the Doñana Natural Area. The subchapter "Monitoring networks for Groundwater Resources and Recent Management Issues of the Doñana" deals with the history and current state of the official monitoring networks for piezometry and hydrochemistry. In the second subchapter "Application of Models in Recent Management and Forecasting of Resources" the current research and the model based water management issues are presented. The third subchapter "Main Knowledge existing on Groundwater Natural Chemical Composition and Contaminant Processes in the Eolian Mantle Aquifer Sector of the Doñana (SW Spain)" provides an overview of hydrochemical research carried out in the eolian part of the aquifer. Subchapter 4 "Active Monitoring Network for Recharge Measurements in the Doñana National Park" presents the current monitoring network for groundwater recharge.
