| Zusammenfassung |
| The HYDROPTIMET Project, Interreg IIIB EU program, is developed in the
framework of the prediction and prevention of natural hazards related to
severe hydro-meteorological events and aims to the optimisation of
Hydro-Meteorological warning systems by the experimentation of new tools
(such as numerical models) to be used operationally for risk assessment. The
objects of the research are the mesoscale weather phenomena and the response
of watersheds with size ranging from 102 to 103 km2.
Non-hydrostatic meteorological models are used to catch such phenomena at a
regional level focusing on the Quantitative Precipitation Forecast (QPF).
Furthermore hydrological Quantitative Discharge Forecast (QDF) are performed
by the simulation of run-off generation and flood propagation in the main
rivers of the territory. In this way observed data and QPF are used, in a
real-time configuration, for one-way forcing of the hydrological model that
works operationally connected to the Piemonte Region Alert System. The main
hydro-meteorological events that affected Piemonte Region in the last years
are analysed, these are the HYDROPTIMET selected test cases of 14–18
November 2002 and 23–26 November 2002. The results obtained in terms of QPF
and QDF offer a basis to evaluate the sensitivity of the whole
hydro-meteorological chain to the uncertainties in the numerical
simulations. Different configurations of non-hydrostatic meteorological
models are also evaluated. |
