Wind Variability over a Small and Sheltered Lake: Trout Lake Field Study

Resseger, Emily L. (2013-02)
Wind is one of the most important, highly uncertain, and least investigated drivers of lake processes. In lake modeling, the wind over a lake is often estimated from point measurements at a remote weather station. Whether ...

Assessing Iron-Enhanced Swales for Pollution Prevention

Natarajan, Poornima; Gulliver, John S. (2015-09)
The treatment of dissolved phosphorus and metals in runoff requires specialized filtration media, which, however, is not accounted for in the typical swale ditch check designs currently employed. In this project, ditch ...

Monitoring an Iron-Enhanced Sand Filter Trench for the Capture of Phosphate from Stormwater Runoff

Erickson, Andrew J.; Gulliver, John S.; Weiss, Peter T. (2015-09)
This monitoring project was performed on an iron enhanced sand filtration (IESF) trench in the City of Prior Lake. Water from the pond and IESF trench discharges into a wetland that ultimately drains into Upper Prior Lake. ...

Temperature and Dissolved Oxygen Simulations for a Lake with Ice Cover

Fang, Xing; Stefan, Heinz G. (St. Anthony Falls Hydraulic Laboratory, 1994-12)
To project the effect of potential climate change on water quality and ecology of lakes in a region, deterministic simulation models for water temperature and for dissolved oxygen concentration have been developed by ...

Testing an Underdrain System under Backwash Flow Conditions for the Chaparral Water Treatment Plant

Ellis, Chris; Christopher, Richard; Mohseni, Omid (St. Anthony Falls Laboratory, 2005-03)
Johnsons Screens was required to test its underdrain system under backwash flow conditions to assess the uniformity of flow discharge throughout the manifold system. To test the system, a basin was built in St. Anthony ...
