A numerical model is set of equations that describe the hydrologic and hydraulic processes that transform rainfall to runoff and move the runoff through the collection/conveyance network. An example is the Green-Ampt equation for infiltration through unsaturated soil.
A modeling software package is an integrated collection of programs that allow the user to organize the input data, define the boundary conditions, solve the numerical model and present the results. Some packages are based on a defined set of numerical models while others allow the user choices in selecting the most appropriate equations for his/her system.
A site specific model is a set of input data, boundary conditions, and run time parameters that are applied to specific watershed and collection system. Site specific models are based on a collection of numerical models and are usually developed within single modeling software package.
