Recent climate change updates to Australian Rainfall and Runoff (ARR) have fundamentally altered how Probable Maximum Precipitation (PMP) is estimated - directly impacting the design of dams, spillways, and other critical infrastructure. Understanding these changes is essential for engineers, planners, and modellers involved in extreme event hydrology.

This 2-hour course provides practical guidance and real-world case studies that step through the development of Australian PMP estimates using the latest ARR climate change recommendations. You’ll gain insights into the revised
- Generalised Tropical Storm Method (GTSMR),
- Generalised Southeast Australia Method (GSAM), and
- Generalised Short-Duration Method (GSDM).

This course provides an opportunity to stay ahead of critical updates in PMP estimation and climate resilience; and gain insights needed to adapt to Australia’s evolving hydrological challenges.

What You’ll Learn

This 2-hour course covers the inherent uncertainties in the estimation techniques and the background that led to the updated guidance. Our expert presenters will address how to: 

  • Transition between GSDM, GSAM, and GTSMR.
  • Interpolate between ARR and PMP events.
  • Estimate PMPs in transition zone.
  • Apply appropriate temporal patterns.
  • Account for new climate projections.

Who Should Attend?

This course is relevant for:

  • Engineers and Hydrologists involved in extreme rainfall and flood modelling
  • Dam Owners and Operators responsible for infrastructure resilience
  • Planners and Risk Managers working on climate-adaptive infrastructure
  • Government and Regulatory Professionals overseeing water safety standards

Format

  • Receive 30 days of unlimited access to the course recordings and resources via the AWS learning platform.
  • Pre-and-post materials to go through via the AWS learning platform.
  • Ability to ask questions to the presenters at anytime through the learning platform.

 

Recommended Knowledge

  • The following AWS course discusses climate change impacts on extreme events hydrology:

This course serves as an ideal lead-in to ARR Course #6: Extreme Events, a comprehensive training on extreme rainfall, PMP/PMF estimation, and flood modelling. If you’re looking for a deeper dive into PMP and PMF assessments, this course will expand on the principles introduced in this session.
