Abstract

Stream temperature is fundamentally important in the structure and function of freshwater riverine ecosystems. The interactions of flora and fauna with chemical constituents, dissolved oxygen and other water quality factors are influenced by stream temperature. Computer models can be used to simulate stream temperature at stream segment resolution (e.g., a network with stream segments between 1 and 100 kilometers long), which in turn can facilitate decision making by ecologists and resource managers. A daily mean stream temperature modeling application, based on the hydrologic simulations of the U.S. Geological Survey’s National Hydrologic Model, has been developed. Preliminary results from this application are presented.
