I believe (not 100% sure) that there was an article in NGM re irrigation etc. Probably in the last 10-20 years.
The article was from a US archeology group, this was their second visit to same site, and described about finds in a valley and the possibilities of sourcing water from adjacent valleys. There were maps outlining the discoveries etc.
Can anyone help me locate this article ? Sorry about the lack of info, what country etc. as I do not remember. Read it at the Doctors surgery some years ago and would like to find again.
Have done a lot of searching but no luck.
Checking the murky depths of metadata:
The September 2002 NGM included a series of articles and a supplement map on water worldwide including at least one on irrigation.
There is a special Water Edition with map in November 1993 including irrigation articles but it only covers North America.
Interestingly, there is an article on this subject from over 100 years ago: May 1916. I wrote a review on it.:
Hope this was helpful.
Hi Tom & Philip
Thanks for your replies. I will follow up and get copies of the mags etc. Much appreciated.
I think I was born a few thousand years too late. A most intriguing period of civilisation and I believe we do not understand fully how advanced they were. No laptops then.
