Project objectives: 
In order to mitigate the risks of saline water intrusion in coastal aquifers, an integrated, multi-scalar hydrogeological characterisation of subsurface 
structures and dynamics is required. The objective of ALIANCE is to develop a strategy for the quantitative description of fluid flow and storage in the shallow 
subsurface. A site-specific, detailed but cost-effective protocol will be implemented, leading to a site modeling capability associated with long-term 
monitoring from pressure and electrical fields. This includes state-of-the-art geological, geochemical, petrophysical, geophysical logging and hydrological 
methods, and the design of 5 new downhole sensors yielding new data for model validation. Two end-member sites in terms of hydrogeological behavior will be 
set up for long-term experimentation, the testing of the new tools, and the validation of site-specific experimental and modelling protocols from µm- to 100 
m-scale. Active in-situ testing from short- and longer-term injections with variable salinity fluids will simulate over-drafting or saline water intrusion. 
In addition to pressure and fluid electrical conductivity, the electro-hydraulic coupling principle will be used to characterise and monitor water/brine 
hydrodynamics.
Project Summary: 
The goal of ALIANCE is to improve the investigation, characterisation and monitoring of coastal aquifers for vulnerability assessment. For this, ALIANCE 
proposes to develop a set of geophysical approaches for the quantitative evaluation of brine intrusion. This includes state-of-the-art geological, geochemical, 
petrophysical, logging and hydrological methods, and the design of 5 new geophysical and hydrodynamical logging/testing sensors yielding new data for model 
validation. Two end-member sites in terms of hydrogeological behaviour will be set up for long-term experimentation, the testing of the new tools, and the 
validation of site-specific experimental and modelling protocols from µm- to 100 m-scale. Active in-situ testing from short and longer-term injections 
with variable salinity fluids will simulate overdrafting or saline water intrusion. The electro-hydraulic coupling principle will be used to characterise 
and monitor water/brine hydrodynamics in coastal environments.
