The feasibility of flash flood forecasting without making use of rainfall predictions is investigated. After a presentation of the “cevenol flash floods“, which caused 1.2 billion Euros of economical damages and 22 fatalities in 2002, the difficulties incurred in the forecasting of such events are analyzed, with emphasis on the nature of the database and the origins of measurement noise. The hi...

For the entire period of recorded time, floods have been a major cause of loss of life and property. Methods of prediction and mitigation range from human observers to sophisticated surveys and statistical analysis of climatic data. In the last few years, researchers have applied computer programs called Neural Networks or Artificial Neural Networks to a variety of uses ranging from medical to ...

Abstract Flash flood events are common in the Mediterranean basin, because of a combination rugged coastal topography and climatological characteristics. The Balearic Islands flood-prone region with research area, Sóller (Mallorca) being no exception. Between 1900 2000, experienced 48 flash floods 17 categorised as catastrophic. In Sóller, local surface water network comprises ephemeral streams...
