Application of two stream water temperature simulation models in the Fenton River-Storrs-Connecticut

In this research, the physically-based WTS (Water Temperature Simulation) model was developed to predict water temperature changes in a river in eastern Connecticut during the summer. The model was applied and calibrated with a one-hour time step during the summer’s low-flow season on the Fenton River, which is tributary of the Mansfield Hollow Lake. Temperatures were recorded at one-hour intervals during the summer in 2004 and 2005, at various locations along the river to provide data for the model’s calibration. Model results were tested against observed stream temperatures and also compared to the SSTemp (Stream Segment Temperature model) created by Bartholow (2002). Results show that both models can be used to predict changes in stream temperature due to changes in groundwater inflow/outflow, and could be used to assess various water management scenarios.
