There are three basic boundary conditions for contaminant transport: 1) specified concentration (Dirichlet); 2) specified dispersive flux (Neumann); and, 3) specified dispersive and advective flux (Cauchy). In many cases, these boundary conditions are sufficient and easily defined.

WebbBoundary conditions allow a simulation design to constrain system behavior based on what is happening in the real system being simulated. In terms of mathematics, … In mathematics, the Neumann (or second-type) boundary condition is a type of boundary condition, named after Carl Neumann. When imposed on an ordinary or a partial differential equation, the condition specifies the values of the derivative applied at the boundary of the domain. It is possible to describe the problem using other boundary conditions: a Dirichlet boundary condition specifies the values of the solution itself (as opposed to its derivative) on the boundary… fish at petersham
