Nothing here goes close to meeting the pub test. No argument with the Feds disaster relief and National emergency declaration but people have to accept that they chose to live in one of the most flood prone areas in the wide brown land.
I note pollies(Littleproud was one) are throwing around “unprecedented” and caving to the GreenLeft by accepting that current floods are due to “climate change”.
I would not accept the “unprecedented” claim until we had a report by independent meteorologists & hydrologists assessing all rainfall and river data back 140 or more years.
[1] The report should contain maps and tables of rainfall stations for every decade so the increase in stations is obvious.
Station numbers would have increased in recent decades making it more likely to register high daily readings.
[2] The report should show by maps and analysis of historic landuse data the increase in areas cleared for agriculture over 140 years. Aerial photos mostly WWII will allow more accurate assessment of land clearing in the last 70 years. Satellite imagery should assist in recent decades. It is well known that rainfall on forested land does not runoff as quickly as on cleared grassed farm land so flood peaks tend to be lower.
[3] The report should show by maps and analysis of historic urban data the increase in urban areas and population over a hundred years because rain on urban paved areas would runoff and contribute to flooding quicker than on farmed or bush areas.
[4] There should be a look-back analysis at post WWII State Govt and council planning changes relevant to building houses and shops/commercial buildings, in flood prone areas and an assessment of levees at Lismore.
