Abstract

A streamflow-routing model was developed to simulate flows that could be used to evaluate stresses on the streamflow characteristics of the Kentucky River near Lexington and Frankfort. The study area was divided into four reaches, and the model simulated daily streamflows at the downstream ends of each reach. Statistical analyses on the observed and simulated flows between October 1, 1940 and September 30, 1981, were compared to evaluate the model. Observed and simulated annual minimum 7-day average discharges compared satisfactorily. Frequency analyses showed the 7-day, 10-year simulated low flow values to be about 7 to 29 percent less than the observed flows. Flow duration curves showed very close comparison between observed and simulated discharges. These statistical results indicate the model was calibrated sufficiently to give reasonable simulated values. (USGS)
