Lecture 03: Boundary conditions — CFD-Notebooks 1.0

Neumann and Dirichlet boundary conditions can be distinguished better mathematically rather than descriptively. Dirichlet boundary condition directly specifies the value of a variable at the boundary, e.g. u(x) = constant. While for Neumann boundary condition, the gradient normal to the boundary of a variable at the boundary needs to be specified.

Boundary Conditions

External boundary conditions must be established at all the open ends of the river system being modeled. These are the boundary conditions you must add to the upstream and downstream ends of each reach (or 2D flow area). Internal boundary conditions are optional and allow the user to define gate operations and add flow within a river reach.

Downstream Boundary Conditions

Setting a downstream depth rather than stage, makes the water surface elevation independent of the computed channel elevation.There is no feedback between bed change and water surface elevation. For stage boundary conditions, if the bed aggrades, shear will increase, and the rate of aggradation will drop until the cross-section approaches equilibrium.
