Hydraulic Boundary Condition

Top Previous Next

Definition

A mathematical statement specifying the dependent variable (e.g. hydraulic head) at the boundaries of the modelled domain which constrain the equations of the mathematical model.

Description

A modelling term describing flow conditions and groundwater levels at specific points within the model. These boundaries typically include: no flow boundaries (e.g. groundwater divides), flux boundaries (e.g. difference hydraulic heads, recharge area) and constant heads (e.g. lake, ocean).

Why are hydraulic boundary conditions important?

These boundary conditions are an important consideration in the modelling of aquifer systems.
