Abstract

Computational models for use in analyzing the hydrologic and water quality response of a watershed have been used for decades, beginning in the early 1960s with the development of the Stanford Watershed Model (SWM), by Crawford and Linsey (1966), followed by SWMM, STORM, BASINS, and LSPC all with increasing complexity. In 2001, the National Research Council review of the EPA TMDL program concluded that: ".the model selection criteria concerning cost, flexibility, adaptability, and ease of understanding all tend to favor simple models." In endeavor to develop a more transparent and stakeholder friendly nutrient model the Kentucky Nutrient Model (KYNM) was developed. In KYNM, hydrologic and water quality transport was modeled using mass balance approaches along with linear reservoir models to accommodate temporal storage and simulate flow and mass attenuation. The model takes into account point source loads, non point source loads, and background loads, including groundwater, erosion, and air deposition. It is a lumped parameter model that provides general estimates of total nitrogen and total phosphorus on an annual basis.
