Abstract
Floods have recently caused significant economic losses and affected a number
of civil engineering structures in many countries including the Czech Republic.
Various protective measures have been considered to reduce adverse
consequences of flooding in future. Decisions concerning expensive measures
should be preferably based on risk optimisation, taking into account cost of
measures, potential societal and economic consequences and losses of cultural
and heritage values in case of historic structures. Methods of probabilistic risk
optimisation seem to provide a suitable tool for identification of the most
effective permanent and temporary measures. Present paper provides general
framework of the risk assessment of heritage structures endangered by fluvial
floods. The total consequences may be assessed using Bayesian networks
supplemented by decision and utility nodes. Further investigations of relevant
input data including societal and economic consequences and losses of cultural
and heritage values are desired.
Keywords: risk assessment, heritage structures, fluvial floods.
1 Introduction
Numerous regions of the Czech Republic suffered from extreme fluvial flooding
in August 2002. Most existing flood protections were overwhelmed and damage
exceeded 3 billion EUR. Emergency measures hastily applied during the
flooding included protective barriers, prompt removal of floating debris from
bridges, additional anchors for river traffic and movement of people away from
endangered areas. Despite these measures, construction works were considerably
damaged. Particularly severe consequences were observed in the city of Prague
