This project will develop and execute three point source related scenarios for the Chippewa River watershed using an existing HSPF watershed model. This project will also support the review of the HSPF Modeling Guidance Document.
This project will complete spatial and temporal revisions , recalibration and validation of 7 watershed HSPF models. These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
This project will maximize the utility and usefulness of three HSPF models that have been constructed and calibrated for hydrology. The contractor will identify and reduce parameterization errors in the following three HSPF models: 1) Buffalo River Watershed, 2 ) Thief River Watershed, 3) Bois de Sioux-Mustinka Watersheds. This will result, not only in a better hydrology calibration, but will also improve each of the models’ ability to more accurately estimate sediment and pollutant loads and concentrations.
The MPCA has selected the Soil and Water Assessment Tool (SWAT) watershed model to simulate watershed hydrology and water quality to assess various restoration scenarios in the Little Cannon River watershed. The SWAT model is an important tool in developing an understanding of existing conditions and simulating conditions under various management scenarios to inform the development of implementation strategies and plans to restore and protect streams and lakes.
This project will finalize the Hydrologic Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The consultant will produce an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that this model generates predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will complete the final Implementation Plan, semi-annual and final reports and hold project meetings. The Implementation Plan will identify target areas and priorities for implementation strategies to improve water quality for Bluff Creek. This project will build the groundwork so Bluff Creek will meet water quality standards for aquatic life in the future.
