Saline Intrusion and Aquifer Salinization Consulting

Due to intense aquifer exploitation in certain coastal areas, done to satisfy the requirements from agriculture, industry, cities and touristic development, the salinization process is intensified and produces a saline front from the sea or deep saline aquifer horizons.

Hatari Labs develops variable density numerical models related to aquifer salinization that consider the main physical process related to saline intrusion. These numerical models have the objective to assess the current and future situation from the groundwater flow regime in terms of flow and water quality.

Mixing Zone Modeling Consulting


Municipal and industrial water treatment plants as well as desalination plants generate effluents that are disposed to different water bodies. The discharge type can be temporal or permanent and the discharge point location could be located on surface or submarine. The main enviromental concern about the discharge is the behaviour from effluent chemicals/nutrients/bacteria on the water body and the associated dilution process to delimitate a mixing area and evaluate the impact on water quality, aquatic ecosystem and dependent species.

Hatarilabs develop mixing zone modeling from effluent discharge on rivers, lakes and oceans, taking into consideration the most relevant conditions related to water quality and flow.


The required baseline for the mixing zone modeling is divided on two main parts:

Water body

  • Bathymetry (precision less than 1m)

  • Water qualiy

  • Flow rate (rivers) or currents (ocean)


  • Discharge rate

  • Discharge geometry

  • Water quality


The numerical tool selected for this evaluation is OpenFOAM with its solver for miscible flow: interMixingFoam. This tool can handle single/multiple discharge points on complex geometries.
