Thank you for your understanding. More information. Use of information about historical floods, i. Such information can be retrieved from archives, newspapers, interviews with local residents, or by use of paleohydrologic and dendohydrologic traces. Various statistical techniques for incorporating historical information into frequency analyses are discussed in this review paper. The basic hypothesis in the statistical modeling of historical information is that a certain perception water level exists and that during a given historical period preceding the period of gauging, all exceedances of this level have been recorded, be it in newpapers, in people's memory, or trough traces in the catchment such as sediment deposits or traces on trees.

Among these methods, the method of Gradex is used in this work for the estimation of the design flood and volumes corresponding to the flow.
This approach has allowed recognizing the flow of different frequencies by the aspects of peak flows and the flood hydrogram. View via Publisher. Save to Library. Create Alert. Launch Research Feed.
