[[Trim\|TRIM]]-2D was designed to solve several depth-integrated transient nonlinear partial differential equations (pde's). The [[model]] is actually used to study one ore more of the following physical processes:

	# evolution of the bottom (morphodynamics) due to suspended load as well as bed load transport		# evolution of the bottom ([[morphodynamics]]) due to [[suspended load]] as well as [[bed load]] transport

	TRIM-2D was jointly developed by Prof. V. Casulli (Trento University, Italy) as well as Prof. R. T. Cheng (US Geological Survey, Menlo Park, California). In the framework of a scientific cooperation TRIM-2D has been successfully installed in the year 1994 at BAW-DHs computers. It has been integrated into BAW-DHs numerical modelling toolbox and is now used on a routine basis in the context of different real-world projects concerning estuarine flow and transport processes. Meanwhile the capabilities of the model were extended and new physical processes have been included.		[[Trim\|TRIM]]-2D was jointly developed by Prof. V.
