What is/are Salt Groundwater?
Salt Groundwater -We developed a high-resolution nationwide 3D fresh-salt groundwater flow and transport model to assess effects of climate change and sea level rise on groundwater salinization in the Netherlands.
[1] In February 2020, geochemical tracers along with hydrochemical and hydrological characteristics were used to reveal a discharge site of salt groundwaters in the head of the Razdol’naya R. [2] In addition to this, in the hinterland, artificial drainage of low-lying polders leads to a salt groundwater surplus that is discharged into rivers and surface water reservoirs. [3] This shows that long-term transient simulations are needed when estimating present-day fresh-salt groundwater distribution in large deltas. [4] This shows that long-term transient simulations are needed when estimating present-day fresh–salt groundwater distributions in large deltas. [5] The co-occurrence of high alkalinity and Cl concentrations, in combination with piezometric and geo-electrical data, suggests that: 1) inland brackish/salt groundwater is caused by mixing with seawater trapped within clay layers; and 2) brackish/salt surface waters result from seepage of brackish groundwater into rivers and wetlands, followed by evaporation, hence increasing salinity and δ18O values.
