Yes. Holes in the ground wouldn't deal with all kinds of root causes. Net rising sea levels would need to be dealt with in other ways. I think this author's focus is on runoff from rain which he sees as one of a group of key root causes.Originally Posted by Terpe
It's an interesting subject and apparantly quite complex.
There was a recent TV report on the potential impacts of Hurricane Isaac on New Orleans considering the billions of dollars spent on flood defences.
Interestingly, there was quite some concern about the volumes of rain expected as the surface drainage and run-off had not been upgraded to cope with the projected amount of rain expected.
The flood and sea-intrusion defences were confidently expected to give protection.
So it seems that solutions would need to be considered for all potential root causes.
Avoidance of land reclamation would need to be addressed too as a futile exercise and some areas affected by sea level rises might need to be deemed lost causes.
Not all holes in the ground would work in the desired way. Permeability would be key to this.
As you say, a combination of solutions is required.
Having said that, cheap holes in the ground ought to be an easy and cheap start to runoff related flooding if funding is an issue.
