As organic disasters will be inevitable, it is necessary that we as humans mitigate the potential effects caused by these kinds of disasters. This kind of essay can explore the 2011 surges of Brisbane and whether proper organizing and planning could have reduced the outcome. It is going to further explore the impact the Wivenhoe Dam had on the floods and discuss whether dam maintenance; level supplies and safety measures could have helped.
December 2010 and January 2011 found Queensland knowledge record-breaking rainfall that has certainly not been noticed since 1960. Approximately you 000 millimetres of rain fall was recorded in January by itself, which caused the second biggest flood Brisbane has skilled since mid 1970s (Hornet & McAneney, 2011: 1150). The 2011 floods caused extreme devastation through Brisbane with over twenty six 000 persons loosing their homes and also 5 500 businesses around the city either partially or completely overloaded. It additional caused around ninety kindergartens and 59 schools to become affected and unusable. Even so the greatest devastation was the loss in twenty-three peoples' lives as being a direct response to the surges (Calligeros, 2011: 4).
The Queensland Federal government also suffered a major financial repercussion from your floods. Over 440 mil dollars was spent in repairing tracks, bridges, power poles and also other public establishments that were ruined (PM With Mark Colvin 2011). This type of spending by Government caused speculation that if proper planning and preparation recently been implemented, the Brisbane floods could have been mitigated. This speculation further bring about the examining of whether the Wivenhoe Atteinte helped or perhaps hindered the floods.
The Wivenhoe Atteinte opened in 1985 following your great Brisbane floods of 1974 took place and was seen as a solution to prevent even more floods from happening once again. All the public works, creeks and rivers surrounding the Wivenhoe Dam were connected that any potential overflow may run towards the Wivenhoe and therefore possess minimal risk of overflowing. However what occurred in 2011 was not the fact that was planned when ever building Wivenhoe many years previously. Wivenhoe Dam was created to hold a water supply of just one. 15 mil millilitres of water, with a capacity to carry 1 . 45 million millilitres at Total Supply Level or FSL. The 35 million-millilitre big difference was allocated as a book for floodwaters to help reduce flooding (Honert & McAneney, 2011: 1152). Although a reserve level had been given in the dam, the issue is that there have been constant and heavy rain fall in the previous springtime months. This led to the Wivenhoe catchments being fairly full before the downpour that occurred in the December 2010 and January 2011. This rain even more caused the surrounding rivers and creeks to overflow creating minor water flooding, with water after that starting to stream into Wivenhoe to help stop major surging.
Prior to the floods Wivenhoe peaked at 1 . 50pm upon Wednesday twelfth of January reaching an astounding 2 . up to 29 million millilitres. (See Appendix 1 вЂ“ Table 1 . 0). Each day later Brisbane River peaked at 4. 46 metres at 2 . 57am upon Thursday thirteenth of January, causing major flooding to start with. (See Appendix 2 вЂ“ Graph installment payments on your 0). It had been during these 2 days that the function the SEQWater played was questioned, because they were which the public works were sufficient to flood. This supposition was further fuelled mainly because it was made known that SEQWater only released 60% in the dam's drinking water, moments ahead of the flood overflow Brisbane (See Appendix a few вЂ“ Table 3. 0).
SEQWater is the firm in charge of the Wivenhoe and Somerset Public works and have 3 simple working guidelines that they can must follow (See Appendix 4 вЂ“ Guidelines 4. 0). It was apparent that non-e of the guidelines were implemented for a number of causes. Firstly it was evident since when the Wivenhoe and Somerset dams started filling up because of the serious wet weather, SEQWater did not release virtually any water from either atteinte until Tuesday 11th of January. Because they had left the water...
