In-depth Hydrological Calibration and Management for Hydropower Infrastructure

This comprehensive calibration approach focuses on tuneable parameters, precipitation correction, and threshold coefficients for surface runoff and quick runoff formation. It includes storage time considerations for surface runoff and interflow, with manual calibration using PREVAH Xml file for discharge analysis. The calibration also examines hydropower infrastructure components like intakes, derivations, storage, and power plants. Analyzing storage accumulation/release patterns in terms of volume, energy demand, and legislation, as well as river bed hydraulics such as slope and geometry, are crucial aspects. The manual calibration process involves RS3.0, PREVAH data flow, communication, and partial time series exported to RS3.0. Regular updates of the PREVAH executable by BAFU and adjustments in the adapter for FEWS integration are necessary.

  1. Calibration approach • Tuneable Parameters • Precipitation correction • Threshold coefficient for surface runoff /quick runoff formation • Storage time for surface runoff • Storage time for interflow Manual Calibration PREVAH Xml-file (discharge) • Tuneable Parameters • Hydropower infrastructure (intakes, derivations, storage, powerplants) • Storage accumulation/release (volume, energy demand, legislations, etc..) • River bed hydraulics (slope, river bed geometry) Manual Calibration RS3.0

  2. PREVAH

  3. Data Flow A

  4. Data Flow B

  5. Communication RS3.0 / PREVAH • Partial times series of the PREVAH-basins exported to RS3.0 • Each partial time series characterized by a unique identifier and its corresponding area • Update of PREVAH executable at BAFU needed • Additional upload from PREVAH to FEWS. Adpater needs slight modifications
