This tutorial has been developed to illustrate how to calibrate the KYNM using two different example watersheds: 1) the Upper Chenoweth Run watershed and 2) the Middle Chenoweth Run watershed. Both models are provided with the KYNM Users Manual. The Upper Chenoweth Run does not contain any significant point sources, while the Middle Chenoweth Run watershed contains several point sources. Calibrating a model of a dynamic system is often not a simple linear process but an iterative one. The following discussion outlines “steps” in calibrating a model, but it must be understood that the phenomena being modeled are interconnected and affect one another, hence it will be likely that these steps may need to be revisited and possibly adjusted, until the desired calibration quality is achieved.
