  • Looking at the ways to mitigate economic disruption after floods, slips or natural hazards
PROFESSOR ILAN NOY, Professor of Economics, Victoria University
Assessing risk for our vulnerable communities - how much is acceptable before adapting?

Dr Rob Bell discusses the frameworks for hazard and risk assessments that incorporate changing risk profiles and for deriving triggers and pathways to reduce risk for exposed communities and infrastructure.

  • Examining the current and future risk exposure of coastal flood and erosion prone communities
  • Hazard, risk and vulnerability assessment frameworks and their application to changing risk profiles
  • Exploring the effects of vulnerability on liveability, disruption, and performance levels of service for engineering lifelines
  • Adaptive approaches to climate change for communities and infrastructure to avoid path dependencies and work around uncertainties
DR ROB BELL, Principal Scientist - Coastal and Estuarine Physical Processes/Programme Leader - Risk Impacts of Weather Related Hazards, NIWA
Lunch break
Leaders’ panel: Exploring New Zealand’s need for strategy around network and community resilience

The leaders across road, rail and other horizontal infrastructure come together to discuss how to best manage the risk to key infrastructure and networks in New Zealand.

  • Examining New Zealand’s areas of key infrastructure vulnerability
  • Understanding the impacts of a disrupted network due to a hazard event
  • Discussing the key changes that need to be made to improve network resilience
  • Is the reality of large scale protection projects or managed retreat possible from an infrastructure investment perspective
TODD MOYLE, Group General Manager - Network Services, KiwiRail
KEN SHIRLEY, CEO, Road Transport Forum
JAMES HUGHES, Climate and Resilience Specialist, Tonkin and Taylor
Managing coastal erosion by working with nature and adaptive management
  • Looking into the modern approaches of the management of coastal erosion and offering different solutions to the challenges faced
  • Understanding managed retreat as a component of adaptive management strategies
  • Examples of managing coastal erosion effectively at difficult sites whilst avoiding the traditional engineering traps
JIM DAHM, Coastal Scientist, Eco Nomos
Key considerations for ensuring infrastructure resilience in New Zealand
  • Know where infrastructure is, co-ordinated effort
  • How infrastructure can be impacted by major hazard events
  • Inter-dependencies, system’s thinking, collaboration
  • Examples of best practice, and latest developments
Roger Fairclough, Managing Director, Neo Leaf Global
Afternoon break
An insurer’s perspective: How can we protect vulnerable locations?

Hear a perspective from the insurance industry on the rising risk of floods, slips and natural hazards and how the industry is responding to this.

  • Exploring the impact that natural hazards have on the insurance industry, and the range of implications for the community
  • Looking into the global reinsurance market dynamic and implications for New Zealand to maintain support in the face of rising climate change costs
  • Exploring un-insurability and avoiding it
TIM GRAFTON, Chief Executive, Insurance Council of New Zealand
Case study: Community based Decision-Making for Coastal Hazard Adaptation in Hawkes Bay

INTERNATIONAL KEYNOTE - Remote sensing and its role in the flood ‘life-cycle’

Flooding is one of the most frequent and costliest natural disasters in terms of lives lost and destruction of property. By 2050 costs of floods in coastal cities alone are said to reach $1 trillion annually.

  • How can remote-sensing help in understanding changes in susceptibility due to sea-level rise and climate change?
  • How can we improve our forecasting capabilities?
  • How can we have better cognizance during the flood ‘life-cycle’?
DELWYN MOLLER, Systems Engineer, Remote Sensing Solutions & California, USA - KEA WORLD CLASS NEW ZEALANDER
Using new technology to monitor landslide stability and safety
  • Using UAVs to monitor and understand slopes
  • The use of sensors and instrumentation to monitor slope stability
  • Case histories of managing risk at landslide sites for workers and the public
  • The role of slip data in informing hazard management
DAVID STEWART, Geotechnical Engineer, Opus International Consultants
Morning break
Building using water sensitive urban design to manage environmental change
  • Examining the need for water sensitive urban design due to a rise in the number of flood and weather events
  • Discussing the best areas in New Zealand to implement water sensitive infrastructure
  • Exploring international examples of water sensitive urban design and what can be learned from them
MEGAN WRAIGHT, Director and Principal Landscape Architect, Wraight & Associates
Floods Past and Floods to Come
  • Warmer temperatures will increase evaporation and consequently rainfall intensity
  • More intense rainfall will further intensify storms through latent heat release
  • Deeper lows and stronger winds will increase the height of storm surge
Erick Brenstrum, Severe Weather Forecaster, Metservice
Lunch break
Flood modelling and forecasting masterclass

Rising incidences of extreme weather events means that councils and stakeholders more than ever need to be aware of their flood risk and where flooding may hit. In this masterclass Dragan Tutulic will instruct delegates and answer questions on how to use the MIKE software products to understand flood models and use  this to manage their area flood risk.

  • Looking at the data and MIKE programmes available for flood modelling
  • Exploring the best kind of modelling for your area
  • Integrating GIS data into flood models · Calculating damage across large areas
  • Using flood models to create accurate forecasts of risk
  • Exploring expert tips and tricks to improve model performance
Dragan Tutulic, Head of Water Resources, DHI Water and Environment
