It is a problem in many countries.
Man in his infinite wisdom has interfered with natural run off areas, rivers and streams all of which have a natural use.
Stupid men have allowed houses to be built on what are natural flood planes, then blames all of this on climate change.
Nature has a way of doing what it does well but man continues to attempt to change it, at his peril!!!!!!!!!!!!
Here in Oz we are currently experiencing very heavy rain in parts of the nation.
Began in northern WA and has moved via NSW to Victoria.
But we have had a bit of an early dry spell, the evaporation has to go somewhere.
