  1. Sistema operazionale per il Canton Ticino MODULO Piccoli Bacini

  2. Schedule: Meeting 18.01.2013 – Bellinzona, 13:00-16:00 • Welcome (WSL-UCA) • Description of the task (WSL-UCA) • Envisaged methodic -> MSc Feb-July 2013 (WSL) • Discussion on the target areas (UCA) • Timeline for operational framework (WSL) • Intermezzo: “Operational Forecast System” (Edric-WSL) • Next Meeting • Varia

  3. Description of the Task

  4. Methodic – Step 1 – PREVAH2D -> 200 m

  5. Methodic – Step 1 – PREVAH2D -> 200 m • Updated daily in standard operation mode • Updated hourly if pre-defined thresholds are • exceeded within the Domain (C2 / Radar QPE) • Latest initial conditions of: • Soil moisture deficit • Interception storage deficit • SUZ, storage for runoff generation from the unsaturated zone • Total baseflow • Snow storage (?) Rain-on-snow?

  6. Methodic – Step 2 – QPE/QPF • QPF by COSMO2 and COSMO7 • C2 8 times per day, C7 3 times per day • QPE: interpolated precipitation, radar QPE, CPC-Product • Persistence: 2-3 hours • Time step -> initially 1h, setup to go down to 5-Minutes

  7. Methodic – Step 3 – Network-Cumulation • Cumulate MCH Rhires for sub-areas • at 50 meters resolution • Sub-areas to be defined. Not to large • (flow-time < 3 hours) • IDF for every pixel with area larger • than a threshold needed to be defined • (e.g. 1 km2, 400 pixels at 50 m resolution)

  8. Methodic – Step 4 – IDF • Use of MeteoSwiss Rhires-Product 1961-2011 (CH-Domain) and • CCHYDRO input data (outside CH). Use of single stations for time • steps < 1h • - Main work of MSc Student: 72h -> 5 Minutes

  9. Methodic – Step 4 – IDF • IDF at 200 m resolution -> selection if and where high resolution • computation is needed • Lead time 24h-120h -> Low-Resolution (200 m) -> Alfieri et al. (2011) • CLEPS • - Lead time 24h-72h -> Low-Resolution (200 m) -> Alfieri et al. (2011) • C7 • Lead time < 24h -> High resolution, selection of high resolution-region • according to QPF/C2 and low-resolution • Alerts based on IDF for “Upstream Precipitation” (T2,T5,T10), • for both high and low resolution

  10. Methodic – Step 5 – Going to hydrology • Hourly time step (later set-up also for 5 Minutes time-step) • Estimation of 0° Isotherm (C2,C7) ->Tobin et al, J. Hydromet. 2012 • Assimilate PREVAH initial conditions and run a simplified soil module • (later -> use of Scherrer et al. Methodology) • Rules for different land uses • Time convolution according to ISO-Chrones • Integration for next 12-24 hours • Output as specific discharge • Thresholds for every pixel > 1 km2. How-to?

  11. Schedule: Meeting 18.01.2013 – Bellinzona, 13:00-16:00 • Welcome (WSL-UCA) • Description of the task (WSL-UCA) • Envisaged methodic -> MSc Feb-July 2013 (WSL) • Discussion on the target areas (UCA) • Timeline for operational framework (WSL) • Intermezzo: “Operational Forecast System” (Edric-WSL) • Next Meeting • Varia

  12. Target-Areas and Alerts: • Discussion on Target areas • TOCE? • Cuccio? • Lombardia? • Criteria to issue alerts for target • areas • Cumulated rainfall alerts • CLEPS: 1d, 2d, 3d, 4d • C7: 1h, 2h, 3h, 6h, 12h, 24h, 48h • C2: 1h, 2h, 3h, 6h, 12h • QPF, PLUVIO, CPC: 1h, 2h, 3h, 6h, 12h • - Hydological alerts?

  13. Schedule: Meeting 18.01.2013 – Bellinzona, 13:00-16:00 • Welcome (WSL-UCA) • Description of the task (WSL-UCA) • Envisaged methodic -> MSc Feb-July 2013 (WSL) • Discussion on the target areas (UCA) • Timeline for operational framework (WSL) • Intermezzo: “Operational Forecast System” (Edric-WSL) • Next Meeting • Varia

  14. Intermezzo: “Operational Forecast System” • Already calibrated areas:

  15. Calibration results Moesa: • Efficiency criteria • Highest discharge per year

  16. Calibration results Ponte Tresa: • Efficiency criteria • Highest discharge per year

  17. Difficulties during calibration process: • - Low NS and Nslog-values for Riva San Vitale_Laveggio, Porlezza, Lugano- Scariolo • Riva San Vitale_Laveggio • Porlezza • Lugano Scariolo

  18. Difficulties during calibration process: • Bsp: Riva San Vitale_Laveggio 2001
