Title: ESTIMATING ECONOMIC DAMAGE FROM FLOODS FOR THE RATIONALIZATION OF FLOOD PROTECTION DESIGN

Author: P. Tsakiris

Year: 2009

Publisher: European Water Resources Association (EWRA)

Description:

The problem of rational flood design has gained priority an all recent studies in EU countries in the framework of the implementation of the Directive on floods 2007/60. The paper focuses on the construction of loss functions for estimating the economic damages in the flood plain under each scenario of a certain exceedance probability. Using simplified linear land cross sections of the inundated area loss functions are constructed for estimating the anticipated average annual economic damage that is the annualized flood risk. This figure is then compared with the annualized cost of flood protection works leading to the rationalization of flood protection works design.
