Conclusion
• The flood forecast platform developed at the University of Minho is
based on the Delft-FEWS platform, and use:
– Hydrological data from: real time meteorological information;
forecasting from atmospheric models; and hydro-meteorological
monitoring
– Hydrological and hydrodynamics models
• Good results from hydrological and hydrodynamics model calibration
allows the prediction of reliable river flows forecasting (key-issue for
flooding early warning)
• The flood forecast accuracy greatly depends on the quality of
precipitation data and on the knowledge of river hydrodynamics.
That is why precipitation gauge stations were recently installed in
river Ave basin, and installation of pressure sensors at flood prone
river stretches are planned.
