Flood sensation: Engineer Ian Chalmers says 2011 Brisbane River flood "could have been avoided"

Paul Tully
This letter was sent to the Minister in August 2012.  It is a telling indictment of the methodologies used (or, worse still, not used) in the January 2011 Wivenhoe Dam Flood crisis which led to major flooding of the Brisbane and Bremer River systems destroying thousands of homes and businesses in Ipswich, Goodna and Brisbane.

Ian Chalmers is a highly respected Engineer whose views cannot be dismissed or pigeon-holed.  His revelations are sensational and debunk many of the theories and explanations - and hearty doses of mutual back slapping - by engineers at the Queensland Floods Commission of Inquiry.  Any sensible person would put more reliance on what Ian Chalmers says than other engineers who have reputations - and their engineering mates - to defend and jobs to protect. 

It will be very interesting to see if the current professional engineering and hydrological data being obtained by Maurice Blackburn Lawyers as a precursor to Australia's largest legal class action coincides with the advice and data collated by Ian Chalmers.  Somehow, I think it will.  All of which will put Premier Campbell Newman in totally invidious position.
 
I will continue to fight for all flood victims to ensure they get the compensation they deserve.  Ian Chalmers has made this task one giant step easier.
 
 
 
 
Dear Minister,
Wivenhoe Dam Gates/ Flooding January 2011.
 
Ian Chalmers
debunks flood
claims
After a considerable amount of research and calculation, I have formed the opinion that this flood and devastation could have been avoided.

Worse still, even after the Lawyers’ Picnic called the “Flood Inquiry” the risk of a repeat of such a flood has diminished little.  I suggest that you look up Albert Einstein’s definition of “Insanity”.
 
However the risk of repetition of the flooding can be dramatically reduced quite simply and at no expense. All it requires is for you to instruct the bevy of bean counters, biro pilots and others that constitute the board of SEQ Water to adopt the following Mindset, Strategy and Tactics in any future flood.
Nobody can predict with sufficient accuracy the intensity and location of rainfall let alone the parameters of the resultant flooding.
 
Strategy: Therefore every inflow into Wivenhoe dam is to be treated as the precursor of a flood of biblical proportions and the following tactics adopted. These tactics are to be maintained until it becomes obvious that the dire assumption is incorrect.

Tactics:  The gates are to be opened when the dam water level rises through Full Supply Level (El.67.00).
The purpose of opening the gates is to stop (or preferably reverse) the rise of the water level in the dam.   In large floods this may take considerable time.
The rate of gate opening is a minimum of 5 gates x 0.50 metres opening per hour.
Such a gate opening regimen has been tested against the January, 2011 floods with favourable results. A copy of the graphs and tabulations is attached for illustration. The raw data is available if you so desire.
As the board members have shown a reticence to do the “right thing” and resign, each January and June I assiduously study the honours awards in the expectation that each of the SEQ Water Board members has been awarded a D.C.M.    (Don’t Come Monday).
Please acknowledge receipt of this submission as I do not wish to die wondering of its receipt.

After this you are free to do with it what you wish.
Yours Faithfully
Ian Chalmers B.E.,B.Econ.
