Information - NH2.02 Advances in radar, multi-sensor and hydrological modelling methods for flash flood forecasting
Event Information
In recent years several actions, carried out both at national and/or at European level, were addressed to increase the data exploitation and observation capacity of the severe rain cells which causes land effect. Advances are obtained in the improvement of radar technology system (i.e. polarimetric capability), in data processing capabilities as well as in the number and coverage of radars network. This session aims at stimulating a discussion about how new and advanced use of radar information could improve the flash flood forecast. Contributions are expected in:
- Current use of radar data in flash-flood forecasting.
- Role of radar data to identify and quantify the uncertainty in the forecasting chain.
- Use of multiparametric-polarimetric quantities in rainfall estimation.
- Exploit the results of COST 717, recent weather radar research to understand, remove and correct observational errors in radar data.
- Impact of physically based rain retrieving algorithms in the understanding of heavy precipitation structures.
- Improvement in radar networks, system and mosaic tools.
- Identify the error characteristics of different radar measurements at a range of scales and how these impact on hydrological models.
- Evaluate the use of radar data and calibration techniques in hydrological models to provide quantitative precipitation forecast (QPF) information for hydrological models, over and above that provided by raingauge networks.
- Assimilation of radar data in hydro-geological models.
- Investigate how radar measurements of precipitation type can improve precipitation rate estimation for input to hydrological models.
- Role of radar pattern in coupling meteorological and hydrological models in small catchments – Rainfall physical or stochastic downscaling models.
- Role of radar pattern in “nowcasting” hydrometeorological models in small and medium catchments.
Presentations addressing the results of research applied projects are especially welcomed.
