When floods devastated South East Queensland in 2011, who was to blame? Despite the inherent risk of living on a floodplain, most residents had pinned their hopes on Wivenhoe Dam to protect them, and when it failed to do so, dam operators were blamed for the scale of the catastrophic events that followed.
A River with a City Problem is a compelling history of floods in the Brisbane River catchment, especially those in 1893,1974 and 2011. Extensively researched, it highlights the force of nature, the vagaries of politics and the power of community. With many river cities facing urban development challenges, Cook makes a convincing argument for what must change to prevent further tragedy.
Explaining the concepts in Australian Rainfall and Runoff to a varied audience requires more sophisticated and nuanced approach than was available in the past. Tony Ladson presented a great paper on this and it is available at his blog site:

Austroads has released its Guide to Bridge Technology Part 8: Hydraulic Design of Waterway Structures, Chapter 5: Bridge Scour. To ensure concurrency TMR has updated their 2014 Bridge Scour Manual to reflect the policy of the Department of Transport and Main Roads with respect to the planning, design, operation and maintenance of scour in bridges.
The second edition of the Bridge Scour Manual, sets out a multi-disciplinary approach to the estimation of the depth and extent of scour required for design of waterway bridges. It is a guide to those involved in the planning, design, operation and maintenance of bridges spanning waterways.
This event will discuss the manual update from a hydraulic, geotechnical and structural point of view.
About the speakers:
Dr. Carlos Gonzalez Carlos experience includes hydrodynamic modelling (1D/2D), hydraulic design of dams and spillways, scour studies, erosion protection design (Bridges, Culverts and Channels) and physical modelling.
Dr. Kamalnath Dissanayake Kamal has involvement in a variety of large scale projects, which include design of deep foundations for offshore channel markers, waterfront structures and bridges. Being a member of TMR team he reviews detailed road and bridge designs works by others regularly.
