Statkraft Hydrologic Forecasting Toolbox
Shyft is an OpenSource hydrological toolbox developed by Statkraft. It is optimized for highly efficient modeling of hydrologic processes following the paradigm of distributed, lumped parameter models -- though recent developments have introduced more physically based / process-level methods.
Shyft's primary end-user documentation is at Shyft readthedocs, where you will find instructions for installing Shyft and getting up and running with the tools it provides.
