Welcome to the Civil and Environmental Engineering 619: Hydroecology class project website for the spring of 2010. This project was undertaken at the new Pond 2 stormwater management research facility in the University of Wisconsin Arboretum in Madison, WI. This facility uses a novel stormwater management approach that routes runoff through a series of vegetated wetland basins that are hypothesized to decrease peak runoff flow rates and total runoff volumes by promoting infiltration and evapotranspiration. Vegetation communities are also expected to decrease the suspended sediment by slowing down flow and to decrease excess nutrient content by using nutrients in the production of above-ground biomass.

Our primary goal in this project was to evaluate how four different vegetation communities differ in their ability to promote infiltration and evapotranspiration, both of which can serve to decrease the total volume of surface runoff. To do this, we implemented a series of soil moisture sensors in each of the four vegetation communities that can track soil moisture over time and provide real-time soil moisture data for future research. Two water table observation wells were also installed to understand how groundwater levels respond to storm events.
