Kanton Tessin / BAFU Hochwasservorhersage

slide2

Calibration

  • Already calibrated areas:
slide3

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

slide4

Kalibrierung RS3.0

Fokus auf:

Zielniveaukurven (saisonale Volumen Verschiebung)

Umleiten von Wasser durch Fassungen, Galerien (geographische Verschiebung)

Strategien Kalibrierung

  • Langfristig (Jahresverlauf)
    • Staureferenzniveau
  • Kurzfristig (Tages/Wochen)
    • Strompreise
  • Rahmenbedingungen
    • Wehrreglement und andere
slide5

Calibration approach RoutingSystem Target Level Curve

Die Target Level Curvewird verwendet um das langzeitverhalten der grossen Reservoire zu simulieren.

Falls vorhanden wird die Zielkurve über gemittelte historische Jahreskurven definiert (in diesem fall 2000-2011)

Falls nicht wird die Zielkurve definiert in dem man den Ertrag des Kraftwerkes optimiert (saisonalen Energiepreisschwankungen nutzen und Überlaufereignisse minimieren)

Sambuco:

64 Mio m3

slide6

Kalibrierung RS3.0

Strategien Kalibrierung Speichermanagement:

  • Kombination von lang- und kurz-fristiger Optimierung
    • Staureferenzniveau
    • Strompreise
  • Führt zu
    • Turbinieren trotz tiefer Preise
    • Turbinieren trotz tiefem Level

Calibration and validation results Moesa:

Calancasca

Efficiency criteria

Moesa Lumino-Sassello

Efficiency criteria

  • Yearly discharge maxima
slide8

Calibration and validation results Moesa:

Mean monthly sum of discharge

slide10

Calibration and validation results Moesa:

Discharge components:

R0= Surface runoff [mm h-1]; R1= Interflow [mm h-1]; R2= Total baseflow [mm h-1]; RTOT= Total runoff [mm h-1]

slide11

Further results, which will be included in the report:

  • Mean monthly water balance for the long-time perios, sum of all years (table)
  • Mean yearly water balance (table)
  • Maps of some water balance variables (whole area)

Composite of 37 PREVAH sub-basins 1998-2010: Left: average annual actual evapotranspiration [mm]; Right: average annual discharge [mm]

Difficulties during calibration process:

  • - Low NS and Nslog-values for Riva San Vitale_Laveggio, Porlezza, Lugano- Scariolo
  • Riva San Vitale_Laveggio
  • Porlezza
  • Lugano Scariolo
