INCIDENT REPORTING : A CASE FOR ‘DIOR’?

INCIDENT REPORTING - A CASE FOR ‘DIOR’*

In the course of research for the recently concluded CIRIA Project RP 568 on 'Risk and Reservoirs1 it became evident that a rigorous approach to risk evaluation would not be appropriate. Such methods require the support of an extensive, detailed and consistent database embracing the service behaviour of a fully representative sample of the dam population notionally at risk - some 2,600 dams in the case of the UK. It can also be argued that in any event, even with such a database, other factors conspire to severely restrict the validity of all but the simplest of analyses designed to identify statistical trends regarding type and frequency of incidents or occurrences. A valid determination of the latter, however, even if relatively simplistic, would assist in refining the semi-empirical FMECA analysis set out in the resulting CIRIA Report C 542 'Risk Management for UK Reservoirs' (Hughes et al (2001)).
