Effect of wetland transformation on groundwater quality and soil salinization in neighbouring agricultural areas
Wetlands, and specially salt marshes, represent the final stage of the filling of depressions, embayments, levelling of marine delta plains and other depositional environments. Due to their origin, they are porous media, with high permeability, permanently flooded, or with very shallow oscillating groundwater table. They are rich in wildlife and among the most primary producers environments in ...
متن کاملOrigins and processes of groundwater salinization in the urban coastal aquifers of Recife (Pernambuco, Brazil): A multi-isotope approach.
In the coastal multilayer aquifer system of a highly urbanized southern city (Recife, Brazil), where groundwaters are affected by salinization, a multi-isotope approach (Sr, B, O, H) was used to investigate the sources and processes of salinization. The high diversity of the geological bodies, built since the Atlantic opening during the Cretaceous, highly constrains the heterogeneity of the gro...
متن کاملFreshwater salinization syndrome on a continental scale
Salt pollution and human-accelerated weathering are shifting the chemical composition of major ions in fresh water and increasing salinization and alkalinization across North America. We propose a concept, the freshwater salinization syndrome, which links salinization and alkalinization processes. This syndrome manifests as concurrent trends in specific conductance, pH, alkalinity, and base cat...
متن کاملWorld salinization with emphasis on Australia.
Salinization is the accumulation of water-soluble salts in the soil solum or regolith to a level that impacts on agricultural production, environmental health, and economic welfare. Salt-affected soils occur in more than 100 countries of the world with a variety of extents, nature, and properties. No climatic zone in the world is free from salinization, although the general perception is focuse...
متن کاملIncreased Salinization Decreases Safe Drinking Water.
O decades, there has been increased salinization of fresh water in many regions of the world. Salinization was previously thought to be an environmental problem restricted primarily to arid regions. However, it is now recognized as a global environmental concern impacting humid regions due to human inputs from road deicers, sewage inputs, and water softeners (Figure 1). In both arid and humid r...
