Summary
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 with Phreeqc or React modules.

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.

MARTHE functions

MARTHE technical product description with main functions.

General functions

  • 1D, 2D or 3D ("full 3D") grids.
  • Calculations by finite volumes on structured grids with possibilities for nested grids.
  • Single or multilayer aquifers (layered aquifers, sometimes separated by a semi-permeable aquitard).
  • Unconfined, confined or semi-confined aquifers in steady or non-steady state.
  • Calculations may include discontinuities such as open water bodies (lakes, gravel pits), local aquifer depletion (and subsequent recharge), including in multilayer aquifers, groundwater flooding (rivers, springs, drains), impermeable walls (sheet pile walls, etc.).
  • Automatic limitation of pumping rates as pump heads are uncovered.
  • Calculation of well hydraulic head according to well diameter compared to the size of the grid cell containing it.
  • Full coupling with hydrographic systems (rivers, drains).
  • Coupled hydro-climatic calculations for rain, evapotranspiration, infiltration and runoff: the GARDENIA computing procedure.
  • Horizontal and vertical anisotropism of permeable areas.
  • Calculation of (direct and reverse) pathlines in steady or non-steady state.

Grids

  • The field corresponding to each layer to be modelled is discretised into a structured rectangular tartan grid.
  • The width of each line and column may differ with local heterogeneity, the density of available information and the level of accuracy required.
  • The grid can be further refined locally with nested sub-grids.
  • Grids can be in vertical cross-sections or radial (cylindrical coordinates).
  • Several million cells can be handled, the maximum cell number depends purely on the physical memory installed.
  • Maximum potential capacity:
    • 3000 columns, 3000 rows, 999 layers, 99 nested layers.
    • Unlimited calculation time steps.

Hydrodispersive transport

  • Hydrodispersive migration of an effuent in the aquifer and the vardose zone.
  • Calculations use the TVD method ("Total Variation Diminishing"), the MOC method (Method of Characteristics) or the Finite Differences method.
  • Chain-reaction degradation
  • Retardation factor, kd partition coefficient (adsorption-desorption)
  • Sorption by Langmuir or Freundlich isotherm.
  • Possibilities for control of injection well concentration by production well concentration,
  • Reactive transport with PHREEQC (USGS) geochemical modules.

Non Saturated Zone, Density effects, Temperature

  • Continuous flow and transfer in the saturated zone and the vadose zone.
  • Energy transfers, water temperature calculations.
  • Density effects due to variations in salinity and/or water temperatures.
  • Influence of temperature on viscosity and degradation coefficient taken into account.
  • Possibility for control of injection well temperature by production well temperature (geothermal doublets).

Automatic calibration, sensitivity analyses

  • Automatic calibration of model parameters, defined per homogeneous zone or per grid cell.
  • Sensitivity analysis to the calibrated parameters.

Specific applications

  • Vertical fracturing simulated by equivalent transmissivity.
  • Semi-pervious vertical or horizontal fractures
  • Gallery networks taken into account.
  • Diphase flows with non-miscible phases: freshwater and salt water, water and air, water and "oil".
  • Gas flows.
  • Vegetation growth taken into account.
  • Nitrate or nitrogen balance resulting from crops.

  • pumping and injection flow rates, rainfall, potential evapotranspiration, air temperature, recharge,
  • permeability, porosity, riverbank clogging, extent of hydrographic network or drains,
  • topographic elevation,
  • setting or release of prescribed hydraulic heads,
  • etc.
