“…Both of them (nutrient and salinity) and water have ecological effects, influencing the presence or type of vegetation that establishes, for example (Morris, ). Finally, in coastal wetlands, all these factors should consider interactions with both groundwater and marine water too (Qu et al, ).…”

Coastal zones are characterized by the interactions between continents and oceans and, therefore, between fresh and salt surface and groundwater. The wetlands of coastal zones represent transitional ecosystems that are affected by these conditions, although little is known about the hydrogeochemistry of wetlands, especially coastal wetlands. In the present study, the hydrogeochemical characterization of coastal freshwater herbaceous wetlands in the Ciénaga del Fuerte Protected Natural Area in Veracruz, Mexico, in the American tropics was carried out per plant community. Four herbaceous wetlands (alligator flag, saw grass, cattail, and floodplain pasture) were monitored to understand the origin of the water feeding these ecosystems, the hydrogeochemical composition of groundwater, and the relationship between the groundwater and ecology of these ecosystems during dry and rainy seasons. The results indicate that Ciénaga del Fuerte is located in a regional discharge area and receives local recharge, so it is fed by both regional and local flows. The chemical composition varied temporally and spatially, creating unique conditions that determined the habitat occupied by the hydrophytic vegetation. The spatiotemporal behaviour of groundwater is one factor that, along with the hydroperiod, determines wetland dynamics and affects wetland biota (ecohydrogeochemistry). Generalist plant communities established in zones of local recharge, whereas other more specialized and/or plastic communities inhabited zones receiving regional flows with greater ion concentrations. This information forms the basis for establishing an appropriate scale (municipal, state, or larger regions) for the sustainable management of goods and services provided by the wetlands.

“…However, more knowledge on the interaction processes between the two is still necessary for effective management of water resources (Keery, Binley, Crook, & Smith, ). A great many methods have been used to estimate the magnitude and/or direction of surface water–groundwater exchanges, including pressure gradient measurements (Anderson, Wondzell, Gooseff, & Haggerty, ; Qu et al, ), temperature profile measurements (Hatch, Fisherm, Revenaugh, Constantz, & Ruehl, ; Irvine, Lautz, Briggs, Gordon, & Mckenzie, ), numerical simulation models (Kalbus, Reinstorf, & Schimer, ; Y. Li, Yuan, Lin, & Teo, ; Sterte, Johansson, Sjöberg, Karlsen, & Laudon, ), geochemical tracers (Jin et al, ; J. Li, Li, & Liu, ; Zarnetske et al, ), and a combination of two or more methods (McCallum, Andersen, Rau, Larsen, & Acworth, ). However, all of these approaches suffer from limitations associated with their spatial and temporal scales and underlying assumptions (Cremeans, Devlin, McKnight, & Bjerg, ; Hatch et al, ).…”

“…Wetland systems are recognized as key hydrological landscape elements and characteristically have nonnegligible hydraulic relationships with surrounding surface water–groundwater systems (Rains et al, ). The interaction between the surface water and groundwater regime has important implications for the effective protection and management of wetland habitat environments (Qu et al, ; Turner & Townley, ). Floodplain wetlands are a specific subset of wetland systems and exhibit a significant wetting and drying that primarily depend on the hydrological regime of surrounding shallow lakes or rivers (Frazier & Page, ; Townsend, ).…”

Floodplain systems are most often hydrologically complex settings characterized by highly variable surface water–groundwater interactions that are subjected to wide‐ranging wetting and drying over seasonal timeframes. This study used field methods, statistical analysis, and the Darcy's law approach to explore surface water–groundwater dynamics, interactions, and fluxes in a geographically complex river‐floodplain wetland‐isolated lake system (Poyang Lake, China). The floodplain system of Poyang Lake is affected by strongly seasonal shifts between dry and wet processes that cause marked changes in surface water and groundwater flow regimes. Results indicate that wetland groundwater is more sensitive to variations in river levels than the seasonal isolated lakes. In general, groundwater levels are lower than those of the isolated lakes but slightly higher than river levels. Statistical analysis indicates that the river hydrology plays a more significant role than the isolated lakes in controlling floodplain groundwater dynamics. Overall, the river shows gaining conditions and occasionally losing conditions with highly variable Darcy fluxes of up to +0.4 and −0.2 m/day, respectively, whereas the isolated lakes are more likely to show slightly losing conditions (less than −0.1 m/day). Although seasonal flux rates range from 7.5 to 48.2 m/day for surface water–groundwater interactions in the floodplain, the flux rates for river–groundwater interactions were around four to seven times higher than that of the isolated lake–groundwater interactions. The outcomes of this study have important implications for improving the understanding of the water resources, water quality, and ecosystem functioning for both the river and the lake.
