iMODFLOW

Model

ImodflowModel(modelname[, check])	Class representing iMODFLOW model input.
ImodflowModel.create_time_discretization(...)	Collect all unique times from model packages and additional given times.

Grid

Boundary(ibound)	Specify the locations of active, inactive, and specified head in cells
Top(top)	The top of the aquifers
Bottom(bottom)	The bottom of the aquifers

Solver

PreconditionedConjugateGradientSolver([...])

The Preconditioned Conjugate Gradient Solver is used to solve the finite difference equations in each step of a MODFLOW stress period.

Packages

ConstantHead(head)	The Constant Head package.
Drain(conductance, elevation)	The Drain package is used to simulate head-dependent flux boundaries.
EvapoTranspiration(rate, top_elevation, ...)	Recharge provides a fixed flux boundary condition to the top layer of the groundwater system.
GeneralHeadBoundary(conductance, head)	The General-Head Boundary package is used to simulate head-dependent flux boundaries.
HorizontalHydraulicConductivity([k_horizontal])	Horizontal hydraulic conductivity [L/T] of the aquifers, between TOP and BOT.
HorizontalAnisotropy(anisotropy_factor, ...)	Horizontal anisotropy is a phenomenon in which the horizontal hydraulic conductivity is not equal along the x and y Cartesian axes.
HorizontalFlowBarrier(id_name, geometry, ...)	Horizontal barriers obstructing flow such as semi- or impermeable fault zone or a sheet pile wall are defined for each model layer by a *.GEN line file.
MetaSwap(boundary, landuse, ...[, ...])	The MetaSWAP package (CAP), provides the input to be converted to a MetaSWAP model, which is an external model code used to simulate the unsaturated zone.
Recharge(rate)	Recharge provides a fixed flux boundary condition to the top layer of the groundwater system.
River(conductance, stage, bottom_elevation, ...)	The River package is used to simulate head-dependent flux boundaries.
StartingHead(starting_head)	The initial head in all cells
VerticalHydraulicConductivity([k_vertical])	Vertical hydraulic conductivity [L/T] for aquitards (between BOT and TOP).
VerticalAnisotropy(vertical_anisotropy)	Vertical anisotropy for aquifers [-], defined as the horizontal hydraulic conductivity over the vertical hydraulic conductivity.
StorageCoefficient(storage_coefficient)	Storage coefficient [-].
SpecificStorage(specific_storage)	Specific storage [L-1].
Well(id_name, x, y, rate, layer[, time])	The Well package is used to simulate a specified flux to individual cells and specified in units of length3/time.
