|shortdescription=The two-dimensional finite difference numerical model TRIM-2D can be used to simulate flow and transport processes in different free-surface flow problems.
The following list of physical processes are taken into account by TRIM-2D:

* shallow water equations
:*local acceleration (inertia)
:*advective acceleration
:*Coriolis acceleration
:*barotropic pressure gradient
:*baroclinic pressure gradient (depth integrated)
:*turbulent diffusion and dispersion
:*bottom friction
:*wind friction
:*time-varying height of control-structures (weirs)
* advection-diffusion equation
:*local rate of change of concentration
:*advctive rate of change of concentration
:*turbulent diffusion and dispersion
:*settling velocity depends on turbulence intensity
* Exchange of suspended sediments between the bottom layer and the water column
:*resuspension of deposited suspended sediments above a critical bottom shear stress (critical shear stress for resuspension)
:*deposition of suspended sediments below a critical bottom shear stress (critical shear stress for deposition)
* bed load transport of sediments
:*bed load transport rate is given by the transport capacity of the flow (vanRIJN, BAGNOLD)
* morphodynamic evolution of the bottom
:*net erosion/deposition due to bed load transport
:*net erosion/deposition due to suspended load transport

Turbulent diffusion as well as dispersion is parameterized using constant coefficients.

With the aid of the numerical model TRIM-2D the following physical quantities can be calculated:

* free surface elevation
* depth-averaged current velocity
* depth-averaged salinity
* depth-averaged suspended sediment concentration
* deposited suspended sediment mass
* bed load transport rate
* deposited bed load material mass
* bottom shear stress
* wind shear stress
* depth erosion
* time varying depth of the bottom

A comprehensive description of TRIM-2D is available in the form of a [http://www.baw.de/methoden/index.php5?title=Mathematisches_Verfahren_TRIM-2D&action=edit&redlink=1 Standard Validation Document] (in German only).
