ANSWERS MODEL: A PLANNING TOOL FOR WATERSHED RESEARCH
The ANSWERS model uses a distributed parameter concept in an effort to model the spatially varying processes of runoff, infiltration, subsurface drainage, and erosion. In designing and developing the model, a conceptual model of the many processes that occur within a predominately agricultural watershed was first constructed. Then, the processes and interactions were logically described in a mathematical structure. Finally, the actual descriptive relationships were selected and fitted into the mathematical model and then tested for validity and accuracy using data from two subcatchments in the Black Creek Watershed in northeastern Indiana. The basic concepts and the pertinent component relationships are described. In addition, sample outputs from the ANSWERS model are included.
