Biography

Vincent Post is a hydrogeologist specialised in coastal groundwater systems and the development and application of reactive transport models. He obtained his PhD degree in 2004 and has worked as an assistant professor in hydrogeology at the VU University in Amsterdam until July 2010 before coming to Flinders.

Teaching

Teaching interests

While my main teaching interests are in the area of groundwater hydrology, I hold a broader interest in geoscience and environmental sciences in general. I am particularly interested in developing learning strategies that integrate on-line and classroom teaching, and in field-based student learning.

Research interests

My principal research interest is coastal hydrogeology, which encompasses a wide range of topics related to groundwater in coastal areas. My particular interests are (i) groundwater and the coastal boundary, (ii) transport processes in coastal groundwater and (iii) the development and application of reactive transport models.

Groundwater and the coastal boundary. The coastline does not form a well-marked boundary for groundwater systems: Intruded seawater occurs below the land, and fresh groundwater tends to flow beneath the seafloor. My research focuses on the characterisation of groundwater systems at the coastline. I hold a special interest in the development of coastal groundwater systems on timescales of millenia, as the effects of past sea level fluctuations and coastline migration have important implication for the salinity distribution and the management of water resources in coastal groundwaters today.

Transport processes in coastal groundwater. The distribution of fresh and saline groundwater depends on the flow of groundwater and mixing processes due to heterogeneity of the subsurface and diffusion. I am currently studying the development of mixing zones between fresh- and saline groundwater due to tidal fluctuations, as well as the temporal dynamics of fresh groundwater lenses in response to transient recharge and tides.

Development and application of reactive transport models. The chemical composition of groundwater is both the result of physical processes (flow of groundwater mixing, and evapotranspiration) and chemical reactions (for example the dissolution and precipitation of minerals). A quantitative framework is required to test our conceptual models of the interplay of these processes, which comes in the form of reactive transport models. I collaborate with Henning Prommer to further the development of PHT3D, and am involved in studies where the PHT3D code is applied to study the fate of arsenic in groundwater, the development of brines below salt lakes and the hydrochemistry of streambed sediments.

Professional and community engagement

I am an editor for Hydrogeology Journal and am actively engaged in the scientific community of coastal hydrogeological research. I have been on the scientific commitee of the Salt Water Intrusion Meetings (SWIMs) and I work with international colleagues to make the outcomes of our research more visible and available to the general public (http://www.swim-site.nl).

I am the principal developper of PHREEQC for Windows, a widely-used graphical user interface for the geochemical code PHREEQC, and a leading developper of the reactive transport code PHT3D and of FloPy, a Python-based library for working with MODFLOW-based models.
