Models are used for many applications such as evaluating the impacts of different sources or predicting the response of different inputs in to a given system. Often only one model is needed for a particular study or application. However, there are times in which multiple models are needed in order to more accurately represent the system or address complex issues. A common application of using multiple models is a watershed model that delivers flow and nutrient loading to either a lake or estuary model. Accurately linking models is imperative to make sure that processes represented in one model, are also being represented in another model. Adding to the complexity of linking models is when there are more than two models involved. This might include a watershed model that links to a lake model which in turn then links back to a downstream watershed model.
