AB: Our current work is focused on investigating the impact of urban development on the temperature of trout streams in urbanizing watersheds. The goal of the project is to characterize this impact, and to produce a robust simulation tool to quantify the impact. A preliminary version of the tool, MINUHET (MINnesota Urban Heat Export Tool), has been developed. MINUHET tracks heat transfer processes associated with the routing of storm water through a development-scale watershed, producing a time series of flow rate and temperature at the development outlet that could potentially serve as input to a stream temperature model. Currently, the tool is capable of modeling runoff volume and temperature from a variety of land uses and the effect of various management practices, including storm water ponds, storm sewers, and rain gardens. A case study will be presented in which MINUHET has been applied to a housing development in Plymouth, MN. The case study includes a comparison of simulated and measured runoff flow rate and temperature, and an analysis that characterizes the uncertainty of simulated runoff based on the uncertainty of watershed parameters.
