IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

An overall consequence model for ecological risk identification, assessment and ranking in daya baya

ABSTRACT
In the last decades, there have been many major accidents with a number of fatalities, economic losses, damage to the
ecological environment and social effect. Attempts have been undertaken to prevent these accidents and to reduce risk
to an acceptable level except for more resorting to costly protective systems. This has been done through the
identification, assessment and ranking management of major risk contributors, which can be accomplished using
quantitative risk assessment (QRA) techniques, and implementation of risk control measures. Consequence assessment
is an integral part of risk assessment. This study attempted to consider a major losses for improving the decisive value
of risk. Firstly, the consequences were broadly categorized and the losses generally quantified in terms of human health
loss, assets loss, ecological loss and social effect loss. Secondly, the quantified assessment of losses was done using a
wide variety of mathematical and empirical models. Finally, as an illustration, the proposed methodology is applied to a
case study of the Pearl River Estuary (PRE). The major environmental risk sources of research area were identified.
Then, the losses and effects of potential explosion accident, liquid leakage release, oil leakage accident and persistent
pollutants continuous emission were assessed using the proposed consequence assessment scheme. At last, the overall
risk for identified environmental risk sources was assessed and ranked.
