Joost Delsman of Deltares, with contributions from our group, modelled the Holocene development of the fresh-salt groundwater distribution along a coastal transect in the Netherlands.
To be able to understand and assess the current fresh-salt groundwater distribution and groundwater velocities one needs to go back a long time; this because of the large intertia of the system. Accurate predictions of the current fresh-salt groundwater distribution is essential for meaningful projections of salt water intrusion under scenarios of future sea-level change, climate change and groundwater abstractions.
The reconstructed groundwater heads, chloride concentrations and groundwater origin matches very well with observations.
