MARTHE: Modelling software for groundwater flows

06.06.2016
MARTHE has been developed by the BRGM for 3D modelling of flows and mass and energy transfers in hydro-systems. Modelling includes aquifers, rivers and vadose zones.

MARTHE (acronym for Modélisation d'Aquifères avec un maillage Rectangulaire, Transport et HydrodynamiquE) is designed for 2D or 3D modelling of flows and transfers in aquifer systems, including climatic, human influences and possible geochemical reactions.

Description of the MARTHE computer code

MARTHE is an application for computing pollutant and energy flows and transport in porous environments (in aquifers) developed at the BRGM. This application, based on the finite volumes method, is a complete code incorporating:

  • single-layer and multi-layer aquifers and 3D,
  • hydrographic networks (rivers, other waterways, drainage),
  • exchanges with the atmosphere (rain, snow, evapotranspiration).

The calculations may also include:

  • mass transfer, for water quality protection,
  • temperature effects,
  • influence of salinity,
  • degradation of pollutants,
  • transfers through the vadose zone,
  • geochemical interactions.

MARTHE: areas of application

MARTHE is designed to model fluid flow and transfer issues in different contexts:

Management of aquifer resources

  • Assessment of water budget components in an aquifer system: rainwater recharge, lateral input from catchment areas, underground circulation and associated flows, year-on-year fluctuations, seasonal storage and release,
  • Hydrodynamic impacts of existing or planned structures: pumping, irrigation, drainage, gravel beds, retention basins,
  • management and optimisation of catchments,
  • studies of the influence of climate variability and predicted climate change impacts,
  • diagnoses of groundwater pollution,

Environment

  • Pollutant infiltration into the vadose zone, percolation to the aquifer followed by groundwater migration,
  • simulation of a pollution plume released from a contaminated zone: pathlines, velocities, downstream concentrations.Modelling hydraulic scenarios for confinement or decontamination,
  • impacts of domestic and industrial landfill on groundwaters,
  • studies of underground storage confinement.

Civil engineering and mining

  • dewatering of excavations
  • hydraulic effects of impermeable walls,
  • below-ground worksites (underground, car parks, tunnels),
  • calculation of mine dewatering and corresponding drawdown.
