  Information - NH2.02 Operational tools for flash-flood forecasting (co-listed in HS)

Event Information
A flash flood can be defined as a very intense phenomenon strongly correlated with the timing of the precipitation characterized by a time of concentration shorter than the time needed to activate any operative warning. The inherent characteristics of the atmospheric and hydrologic processes involved in flash-flooding provide a severe challenge to hydrologists, engineers and risk managers. An operational forecasting and warning system should be capable of coping with extreme spatial and temporal rainfall variability, uncertainties in rainfall nowcasting (due to the nature and to the limited space and time scale of the relevant atmospheric processes), hydrological modelling of rainfall-runoff processes (most pertinent model structure and relevant uncertainty), and forecasting in ungauged catchments for which little or no measured data are available. These topics should be given particular attention for operational applications of flash-flood forecasting and submissions in the following subjects will be welcomed in this session:
Real-time flash-flood forecasting
Rainfall-runoff modelling for flash-flood forecasting
Flash Flood Guidance, including use of rainfall threshold methods
Use of quantitative precipitation forecasts and estimates to establish precipitation thresholds
Forecasting of flash floods in ungauged catchments
Reduction and characterisation of uncertainty in estimates and forecast.
