Presentation of the key themes of the guideline and the matters that require resolution. The key themes cover:

• Protecting the community,
• Legal requirements, communication,
• Stakeholder involvement, training,
• Exercising and competency,
• Skills and relevant experience,
• Debriefing and lessons learned.

This will give delegates a good feel for what is covered by the guideline.

An interactive workshop session with the dams industry to consider the following broad topics which will help inform the resolution of outstanding matters:

• Guideline structure
• DSEP structure
• Skills, experience and competences required for DSEP drafters
• Competency requirements for people implementing DSEP’s
• DSEP exercise and review frequencies
• Flood inundation map format

Navigating the ANCOLD Earthquake Guidelines and Implications of NSHA18:

• Discussion on Risk Based and Standards based approaches
• Background, recent developments and update to NSHA18
• Basis and Advantages for using a revised NSHA18 based on using moment magnitude
• Basis and Advantages for using ground motion displacement based magnitudes for determination of site ground motion recurrence.
• Outcome of recent Geoscience Australia meeting on use of NSHA18.
• Implications for Dam Assessments

Steven Pells, Pells Consulting

The masterclass presents a framework for assessment of erosion of unlined spillways. A summary of currently available methods is presented along with guidance on their use and efficacy. The masterclass is structured to clarify three questions that are commonly asked:

1. How do I use Comparative Erosion methods, and how good are they?
2. Can I model rock mass erosion analytically?
3. Where is the industry at with coupled modelling of hydraulics and rock-mass erosion?

The masterclass is presented by Dr Steven Pells. Steven completed his PhD on the subject of spillway erosion in 2016 and has since been actively involved in the dams industry, with particular focus on spillway erosion issues in Australia and abroad.
