Stream Temperature Modeling: A Modeling Comparison for Resource Managers and Climate Change Analysis
Abstract (from http://scholarworks.umass.edu/cee_ewre/72/): In the Northeast U.S. increasing stream temperatures due to climate change pose a serious threat to cool and cold water fish communities, as well as aquatic ecosystems as a whole. In this study, three stream temperature models were implemented for two different case-study basins in the Northeast Climate Science Center region. Two coupled hydrology-stream temperature (physical) models were used: VIC-RBM and SWAT-Ficklin et al. (2012). The third model implemented was a nonlinear regression (statistical) model developed by Mohseni et al. (1998). Metrics were developed to assess these models regarding their prediction skill, data input requirements, spatial...

Survivability of aquatic organisms has been linked to stream temperature regimes. Climate change is anticipated to alter the current thermal patterns in riparian ecosystems and will have implications for these organisms. A water temperature change of 1 or 2 °C may have severe consequences for aquatic species, specifically coldwater fishes. Monitoring and modeling of stream temperature regimes is critical to assessing the vulnerability of coldwater species under the impacts of climate change in the Northeast United States. This research reviews the literature on existing stream temperature models for applicability over varying spatial and temporal scales. Collection of existing stream temperature data in the Northeast...
Water temperature is one of the important characteristics of a stream that can be impacted by anthropogenic change. Such change can have significant ecological implications for the health of riparian systems. It is important for decision-makers to understand the impact of various physical characteristics on the stream temperature regime in a watershed. This research applies a statistical stream temperature model (Mohseni et al, 1998) to 905 sites across the northeastern United States to determine if such models can be useful to resource managers. Statistical analysis on the calibrated model parameters across the best-fit sites is used to provide information on watershed characteristics which may be critical to stream...
