Significance and Use Accurate definition of boundary conditions
is an essential part of conceptualizing and modeling groundwater
flow systems. This guide describes the properties of the most
common boundary conditions encountered in groundwater systems
and discusses major aspects of their definition and application
in groundwater models. It also discusses the significance and
specification of boundary conditions for some field situations
and some common errors in specifying boundary conditions in
groundwater models. 1.1 This guide covers the specification of
appropriate boundary conditions that are an essential part of
conceptualizing and modeling groundwater systems. This guide
describes techniques that can be used in defining boundary
conditions and their appropriate application for modeling
saturated groundwater flow model simulations. 1.2 This guide is
one of a series of standards on groundwater flow model
applications. Defining boundary conditions is a step in the
design and construction of a model that
