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 goal of this project is to construct, calibrate, and validate a watershed model using Hydrologic Simulation Program FORTRAN (HSPF). The project will result in a HSPF model that can readily be used to provide information to support conventional parameter TMDLs.
This project will complete the development of two watershed HSPF models for the Mustinka River and Bois de Sioux River watersheds. These calibrated and validated executable models will simulate hydrology at the 12-digit HUC subbasin scale.
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 address United States Environmental Protection Agency (USEPA) comments on the Preliminary Draft Total Maximum Daily Load (TMDL) study and Minnesota Pollution Control Agency (MPCA) comments on the pre-public notice draft Watershed Restoration & Protection Strategy (WRAPS) report, and produce Public Notice Draft TMDL study and Public Notice Draft WRAPS report ready for public review and comment.
The primary objective of this project is to extend the simulation period of the Two Rivers Watershed Hydrological Simulation Program FORTRAN (HSPF) model through 2017 to support future simulation and assessment of the planned Klondike impoundment.
This project is the second phase of updating the Two Rivers watershed Hydrologic Simulation Program FORTRAN (HSPF) model. This project includes calibration of the model and including a proposed impoundment in the model. An analysis of possible downstream water quality impacts will also be done.
