“…For the transport simulation in the aquifer (MT3DMS/SEAWAT software), the longitudinal and transverse dispersivity ( αL , αT ) were set to 3.6 m and 0.36 m lengths, respectively (Perera, Jinno, Hiroshiro, & Tsutsumi, ; Shoemaker, ), and the molecular diffusion to 1.0 10 −10 m 2 /d. Fresh water density was set to 1,000 g/L and salt water density to 1,024.5 g/L.…”

“…The model results were compare with the TDS observation data from the wells located outside the urban area and close to the boundaries, selected as representatives for the regional unmodified salinity condition. For the transport simulation in the aquifer (MT3DMS/SEAWAT software), the longitudinal and transverse dispersivity (αL, αT) were set to 3.6 m and 0.36 m lengths, respectively (Perera, Jinno, Hiroshiro, & Tsutsumi, 2008;Shoemaker, 2004), and the molecular diffusion to 1.0 10 −10 m 2 /d.

The coastal plain of the Río de la Plata constitutes a large wetland which develops on the right margin of the river estuary. Anthropic activities such as intensive exploitation of groundwater carried out in the vicinity of the wetland can modify the natural hydrological regime. The aim of this work is to asses the effects of intensive aquifer exploitation in coastal wetlands using hydrogeological models. Such models allow to evaluate changes in the environmental conditions of wetland at regional level. The hydrogeological model exposed in this work shows how the intensive groundwater exploitation affects the wetland area, generating important variations both in the groundwater flows and in the salinity of the groundwater. Identification of these modifications to the environment is important to generate guidelines leading to minimize these affectations.
