Temporal Analysis On Flood Risk Management

Abstract
The escalating frequencies and changing patterns of climate change impacts,
such as precipitation rates and sea levels, question the reliability of the existing
engineering infrastructure, in terms of design and planning criteria for which
designers and decision makers need to or account for. The objective of this paper
is to assess the performance of an existing engineering infrastructure by
measuring three variables: Vulnerability (β), Reliability (α), Resiliency (γ).
These variables will be implemented temporally to a floodplain catchment,
where performance and engineering sustainability can be depicted. The depiction
will define the system’s behaviour upon a natural event such as precipitation or
sea-level rise. Nevertheless, Flood Risk Index (FRI), which depends on (β, α and
γ), will be applied as an overall index to demonstrate the trend context as well as
give implications of the sensitivity significance of β, α and γ. The main outcome
of this paper is to depict the relative sustainability or as known as the
performance assessment indicators temporally; and to examine the correlation
between the indicators on a real-flow data. These procedures shall ultimately
provide implications on the implementation of the indicators to achieve a
relatively sustainable system.
Keywords: reliability, vulnerability, resiliency, flood risk index, sustainability,
performance assessment.
1 Introduction
In the last decade, more frequent storms and sea level rises have been observed
and monitored in Australia due to climate change especially southeast
Queensland; which results in the increase of floods in many areas that already
prone to flood. Consequently, new floodplains will emerge to cope with such an
