Metodology to evaluate the risk of vulnerable failure scenarios in a water pipe network

Abstract

The emerging theory of vulnerability of water pipe networks intends to give an important contribution for the design of this important component of water supply systems, as well as, for the assessment, rehabilitation and management of the existing ones. The fundamental contribution of this theory is to design water pipe networks more robust since it is able to identify the most vulnerable parts of them. The concept of vulnerability is associated with the disproportionateness of the failure consequences in relation to the initial damage. It is not a theory of robustness. The main objective of this research work is to explain how the risk of a vulnerable failure scenario of a water pipe network may be accessed and how the theory of vulnerability can be relevant.
