Interpretive Summary:

Technical Abstract: Hydrologic and water quality models have been used as prediction, simulation, and assessment tools for several decades. Using such models for devising proper management strategies to predict surface and ground water quality has become increasingly popular since the early 1980's. Many users, however, have violated the use boundaries for these models and have gone beyond the recommended model limitations. For example, a management model designed for determining the relative impacts of alternate management practices has been forced to predict storm events. Such misuses have occurred in compiling input parameter values, output analysis, and scale and domain of use. This presentation addresses proper and improper usage of process oriented, field scale, and watershed scale models. Results are intended to promote our understanding of model boundaries and help to reduce their misuses.
