watershed modeling : interaction between data structure and model and its impact on model selection

interaction between the data and models is very complicated in the water domain unfortunately in conventional modeling exercises this interaction is often overlooked in this situation a very common belief is the choosing a more sophisticated model leads to more accurate results although the fact is that application of a very simple conceptual model chosen according to available data structure will lead to a more realistic results in this paper a multi -tier good practice paradigm for modeling is proposed the approach involves identification of a watershed management issue/problem selection or development of a simple conceptual model appropriate to the database available and application of the model to address the identified problem .
