EGS XXVI General Assembly, Nice, France, March 2001

NH4.02 The use of historical data in natural hazard assessment: Palaeofloods and historical evidence

Event Information

It is well known that flood analysis must be done with the maximum precision due to its social and economical implications. The traditional way of dealing with this problem is using a series of storms and/or flood events recorded in a gauge station during the last 10 to 100 years. However this is a relative very short amount of information for the extreme flood hazard estimation and the long term flood frequency and magnitude trend analysis. One way to solve this situation is to use the maximum temporal length of information, including in the analysis paleofloods and historical floods previous to the systematic record. This is not the first time this session is organized. In the last EGS General Assembly this session was a big success. Papers and posters were presented covering the full view of this topic: paleoflood and historical data collection, hydraulic simulation of historical floods, trends in long series and frequency analysis. It is our opinion the topic was not closed. We have again the opportunity to join in the same room geologists, historians, hydraulics, hydrologists, meteorologists and statisticians sharing a common objective.
