The goal of this project is to construct, calibrate, and validate one fine-scale Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Duluth Watershed Restoration and Protection Strategy (WRAPS) project area for the simulation period 1995–2012. In addition, an existing condition (post-2012 flood) model scenario will be developed for use in WRAPS development. The contractor will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs.
The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will gather watershed data necessary for the development of a comprehensive watershed management plan with parameter-specific thresholds that will maintain or improve water quality for the Kawishiwi Watershed.
This project will provide technical, planning and engineering assistance to the MPCA for the development and implementation of the St. Louis River Remedial Action Plan (RAP). USACE and USEPA in partnership with the MPCA will administer work plans to complete a sediment assessment for Minnesota areas within Superior Bay, St. Louis Bay, Lower St. Louis River and the Upper St. Louis River, encompassing approximately 5,349 acres of the St. Louis River and Estuary.
This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
