Estimating Changes in Sea Level
Extremes Under Conditions of Rising Sea Levels (pdf 110k)
John Hunter, Antarctic Climate & Ecosystems CRC,
TAS
Climate change alters the frequency of high sea-level extremes. This is
mainly due to the rise in mean sea level rather than to any variation in
the height of the extremes relative to the mean. It is therefore
possible to provide a good estimate of the probability of future
extremes using existing local sea-level statistics (from observations
and/or modelling) and projections of the rise in mean sea level during
the present century.
Anuga The Free Ocean
Impact Model (pdf 678k)
Rudy Van Drie, Balance Research and Design, NSW
In December 2006 The Australian National University and
Geoscience Australia released to the public a Free 2D Unstructured Grid,
Finite Volume, Hydrodynamic Model. The model was a resultant of a
Mandate put to GA by the Australian Federal Government to build capacity
to identify and manage Hazard and Risk. This was interpreted and
actioned by providing a software tool to aid in assessing the impact of
tsunami.

Three Pass Assessment Approach to
Coastal Risk Management (pdf
120k)
Chris Sharples, James Carley University of Tasmania, TAS
Clive Attwater, SGS Economics & Planning, TAS
This paper identifies the essential elements of a properly comprehensive
coastal sensitivity assessment, and suggest a conceptual framework for
considering these. Such a framework can reduce the apparent
confusion of differing methods and make it easier to understand the role
that various methods and approaches play in a coherent overall strategy
of coastal sensitivity assessment; and the suitability of particular
methods for particular coastal types.
Modelling Coastal Processes & Hazards to Assess Sea Level Rise Impacts (pdf
402k)
James Carley, Matt Blacka, Ron Cox, WRL, UNSW, NSW
Clive Attwater, SGS, Phil Watson, Clarence City Council
This paper details the range of coastal processes and hazards considered
in estimating coastal risk for Clarence City, Tasmania. The
processes considered in this paper include tides and storm surge,
extreme open ocean waves, swell wave penetration and local wind waves.
Hazards quantified include erosion, recession, estuary entrance
stability, wind blown sand, inundation and sea level rise.
Establishing Triggers for Adaptive
Response to Climate Change (pdf 112k)
Clive Attwater, Ellen Witte, SGS Economics & Planning
James Carley, Water Research Laboratory UNSW
This paper presents a framework for establishing triggers that can be
used to invoke detailed planning and
action in a timely and appropriate manner that keeps risk to acceptable
levels, allowing the beneficial use of coastal areas while conditions
allow.

Sea Level Rise & Climate
Change Impacts for Planning a New
Hospital (pdf
705k)
James Carley, Matt Blacka, Ron Cox, WRL, UNSW
James McIntosh, Jane McArthur, Pitt & Sherry TAS
This paper details the methodology used to assess the risk due to sea
level rise for the proposed new hospital. Furthermore it describes the
limits of existing data in extrapolating to extremely rare events, and
how with future sea level rise, what are presently considered to be
extremely rare water level events will become commonplace. Adaptive
management options for dealing with sea level rise on the site are
presented, which includes a recommended freeboard in excess of normal
building code requirements.

TAS
This paper outlines how broadening the considerations can lead to more
sustainable solutions acceptable to both coastal communities and the
wider community that use coastal areas.
Adaptable Solutions for an
Uncertain Future and the Role of Cost Effective Monitoring: Kingscliff
Foreshore Protection and
CoastalCOMS (pdf 102k)
Dan Messiter & Jane Lofthouse, Worley Parsons, NSW
There is currently widespread focus on defining climate change
outcomes and associated risks.
While this sentiment is well placed, the enormity of that particular
task is challenging to say the least, with the “goal posts and
playing field” constantly changing at unknown rates. From a
coastal engineer’s point of view it is important to continue
concentrating on practical management solutions to coastline hazards
that are adaptable into the future in the face of uncertain
environmental conditions and associated risk.
The Changing Coast: Providing Room
for Natural Adjustments (pdf 356k)
Chris Sharples, University of Tasmania, TAS
Clive Attwater, SGS Economics & Planning, TAS
This paper explores how allowing natural adjustment of coastal areas may
provide benefits in cost savings for property protection and enhanced
coastal values, both for human use and protection of ecosystem
values.

Anticipated Response of Coastal
Lagoons to Sea Level Rise (pdf 216k)
Dr Philip Haines, BMT WBM, NSW
Dr Bruce Thom, Wentworth Group of Concerned Scientists
Coastal lagoons, or ICOLLs (Intermittently Closed and Open Lakes and
Lagoons), are a common feature on the south-east coast of Australia
(particularly in NSW). Their environmental processes have evolved in
response to their unique hydrological behaviour, which is dependent on
both catchment and coastal processes and inputs.

arise out of planning decisions.
Planning Schemes & Legal
Issues: Adjusting the Instruments to Changing
Conditions
(pdf 146k)
Paul Howorth, Clive Attwater, SGS Economics & Planning,
ACT
Planning has what may be described as a ‘special duty of
care’ to populations and localities in relation to how it balances
and accounts for known and emerging land use issues. Planning schemes
are the instruments through which local governments implement this
duty.

Bearing the Cost: Setting Price
Signals & Cost Sharing to Ensure a Soft
Landing (pdf
161k)
Clive Attwater, Ellen Witte, SGS Economics & Planning,
TAS
Many residents in coastal areas that are at low risk in the absence of
climate change will be adversely affected by changes that are beyond
their control. There is a significant case that such residents have a
claim on wider society for assistance should additional costs be imposed
for protection, adaptation or withdrawal due to sea level rise and
directly related effects.
Decision Making for Local
Government (pdf
134k)
Khondker Rahman, Peter Gibson, Connell Wagner, QLD
This presentation will discuss why climate change will create new and
additional leadership and governance opportunities for local
governments. It will expand on ‘mitigation’ and
‘adaptation’ measures local councils can put forward to
prevent climate change, in particular the impacts on rising sea levels
to highlight the range of operational opportunities available to
councils.

Coastal Zone Conjunctive Flood
Modelling (pdf
182k)
Garry Tong, Principal Consultant – Water, Maunsell
Australia Pty Ltd
The paper draws attention to the need for coastal zone flood analysis
and mapping to be based on
a conjunctive approach which combines the annual probabilities or
average return intervals (ARIs)
of storm events on catchments (meteorologic) discharging against
essentially unknown sea
conditions (primarily astronomic).
