Flow Solvers#

This section groups solver documentation for the flow process.

Use it when the main output of interest is hydraulic head, water-table depth, groundwater storage, recharge response, or flow-budget terms.

The hierarchy is:

  1. process: flow,

  2. solver type or family: MODFLOW family, Boussinesq family, or shared numerical support used by flow solvers.

Current Flow Solver Families#

Family

Solver names

Role

MODFLOW family

modflow_nwt, modflow6

Structured-grid and MODFLOW 6 groundwater-flow backends. Internal structure: MODFLOW 6 and MODFLOW-NWT pages, plus the cross-cutting comparison, worked cases, and transport coupling.

Boussinesq family

boussinesq

In-house shallow-groundwater finite-volume backend. Consolidated theory page: Boussinesq Theory.

Shared flow numerics

Applies to several flow solvers.

See Mesh And Discretization Strategies, Vertical Representation And Storage Assumptions, and Field-To-Cell Parameter Transfer.
