“…6-Groundwater-November-December 2019 (pages 895-906) Some authors have claimed that intensive groundwater extractions in the coastal resort have caused the drying out of the Brezo and Charco del Toro ponds (Figure 1a), the two closest ponds to the pumping area, just 0.7 km from Matalascañas (Serrano and Serrano 1996;Muñoz-Reinoso 2001;Rebollo et al 2008;Serrano and Zunzunegui 2008;Dimitriou et al 2017). Additionally, the hydroperiod and maximum flooded surface area of other ponds have been reduced (Díaz-Paniagua and Aragonés 2015; Dimitriou et al 2017). Due to this situation, some studies have been carried out with the purpose of establishing whether the Santa Olalla pond is being adversely affected in a similar manner (Sacks et al 1992;Lozano et al 2002;Fernández-Ayuso et al 2018).…”

Time series analysis methods have been used to detect behavioral patterns in a set of nine time series. These series contained information in a 3‐h time step about meteorological, hydrological and tidal data of a sand dune pond area located in Doñana National Park in the southwest of Spain. The methods used, such as wavelet analysis and additive seasonal decomposition, had never been applied before in the types of ecosystems studied. These approaches have improved the current knowledge of the conceptual model of the Santa Olalla pond system, the only system with a permanent hydroperiod located in this protected area. In addition, complex surface water‐groundwater interactions, not visible through descriptive methods, have been distinguished to have a strong seasonal component. Finally, we evaluated the effect of pumping activity in a nearby coastal resort on the water supply of the Santa Olalla pond system. Although direct damage to this sand dune pond has not yet been identified, special attention must be paid in order to maintain groundwater inputs that are integral to maintaining its current status.

“…The groundwater abstraction rights for urban water supply at the coastal resort are capped at 2.75 millions m 3 per year, although some authors state that real consumption is higher [3]. This water is pumped by five wells located in the coastal resort.…”

“…From the last decades it has been subjected to differents pressures, especially due to crop irrigation and water consumption in the coastal resort "Matalascañas" [3], located only 3.8 km from Santa Olalla pond and less than 1 km from other died out ponds such as Charco del Toreo (Figure 1). In this type of ecosystem, the groundwater discharge/recharge is the most difficult component of the water balance to quantify.…”

Abstract:We have modeled groundwater inputs to Santa Olalla pond, the only permanent pond of Doñana Biological Reserve (Andalusia, Southern Spain) by means of the application of a thermal modelling methodology. During the study period (February-May 2017) a chain of thermistors obtained hourly temperature data from the surface water and the groundwater in the sediment below. In addition, water level in the pond and in the aquifer near the shores was also monitored at similar time rates. Results showed that a net groundwater discharge occurs heterogeneously through the pond's bed. The comparison of these outcomes with previous studies made in the pond, such as hydrological water balances, is coherent and strengthens the existing hydrological knowledge of this water body. Finally, it has been detected that the pond is strongly influenced by the alterations of the sand aquifer, even if such alterations are produced away from the pond and at high depths. The effects of groundwater extractions for urban supply of a nearby coastal resort are immediately affecting the evolution of the water level, although this effect is not necessarily translated to water level depletion.

“…The Saint-Venant equations can be simplified using the kinematic wave [10] or diffuse wave approximations [11]. For example, MIKE-SHE [12,13] is a model further developed based on the SHE model provided by Danish Hydraulic Institute in the early 1990s, which has been widely used in the resource and environmental issues related to surface water, groundwater, and their dynamic interactions [12,14]. Singh and Bhallamudi [15] developed a mathematical model to simulate the slope runoff by combining surface and subsurface water flow.…”

“…However, there are a few 2D and 3D models that support simulation of preferential flow and transport. Five 3D soil and groundwater flow and substance transport models were found that simulate preferential flow and transport, including HILLFLOW [36], TOUGH2 [37], HYDRUS-3D [38], MIKE-SHE [12,13], and a model by Laine-Kaulio et al [39]. In addition, Blessent et al [40] used the FRAC3Dvs numerical model to compare the dual porosity, equivalent porous medium, and the discrete fracture matrix diffusion conceptual model, and the study has an important role in decision-making for groundwater-related issues, while the research focus is the 2 Geofluids groundwater and the three models do not consider the surface runoff movement.…”

Experimental and Numerical Investigations of Influence on Overland Flow and Water Infiltration by Fracture Networks in Soil

Preferential flow is common in clay or expansive clay soils, involving water bypassing a large portion of the soil matrix. Dye tracer experiment and numerical modeling are used to simulate the surface runoff and subsurface preferential flow patterns influenced by the soil fracture network of a relatively steep hillslope system (slope angle equals to 10 degrees). The result of the experiments indicates that part of the water is infiltrated through cracks, leading to the delay of the initial runoff-yielding time and reduction of the discharge of the surface runoff. The soil water flow is mainly in the matrix when the intensity of precipitation is low. With the increasing of precipitation, soil water movement may become in the form of preferential flow through cracks. In addition, the nonuniformity of soil water infiltration and the depth of the average water infiltration increase as the precipitation intensity increases. To this end, the complete coupling model was established by using the surface-matrix-crack (SMC) model to simulate water flow within discrete fracture as well as to simulate water flow in the soil matrix based on the concept of dual permeability using the traditional Richards' equation. In this model, the "cubic law" of fluid motion in cracks within smooth parallel plates and the two-dimensional diffusion wave approximation to Saint-Venant equations with momentum term ignored (two-dimensional shallow water equations) were used. The model divides soil water infiltration into two forms and uses the overall method to calculate the exchange of water between the crack networks and matrix regions as well as the exchange water between surface runoff and infiltration water. Results indicate that the SMC model has better performance compared with the traditional equivalent continuum model when those models are used to simulate the surface runoff movement and the soil water movement in the presence of cracks.
