| Thesis Title: | Evaluation and Use of Stream Temperature Prediction Models for Instream Flow and Fish Habitat Management |
| Thesis Summary: | Water temperature strongly influences survival, growth and reproduction of aquatic biota. Changes in flow rates, loss of streamside vegetation, and other human activities can alter a stream's temperature regime thereby having a negative effect on fish and other aquatic biota. Predicting the effect of such hydrological and watershed land-use changes or remediation actions prior to their implementation is possible with stream temperature prediction models. We evaluated three temperature models that can predict stream temperature under different flow, riparian shading, and stream width options. The models were evaluated according to parameter sensitivity, predictive ability, ease of data collection, and user friendliness. Thermal, hydrological, and meteorological data was collected to develop data files necessary to run the models. The models were used to predict quantity and quality of instream habitat in the Smith River (Bassett, VA) and Back Creek (Roanoke, VA) in terms of temperature ranges required for present fish species. The models also allowed the influence of different hydrological and watershed land-use changes on temperature to be assessed. Under these different scenarios the model output provided indication of whether or not certain changes will have a detrimental or beneficial effect on the stream's fish species. |
