NEWS NOTES ON SUSTAINABLE WATER RESOURCES  The Great Marib Dam  https://en.wikipedia.org/wiki/Marib_Dam    Everyone knows about the seven wonders of the ancient world – but there is a monumental structure archaeologists and historians like to call the eighth wonder of the world: the Great Marib Dam in southern Arabia, in what is today Yemen. The ancient society there demonstrated great engineering ingenuity in order to take advantage of the periodical monsoon rains. Without water there is no life. True to this maxim, the subjects of the ancient Kingdom of Sheba in Marib collected water by building a gigantic dam so as to be able to supply their cities with this precious liquid.  As the Sabaean kingdom developed, they built a huge earth filled dam in the second half of the 6th century BC to hold back some of the water that came down the wadi. From the lake that developed behind the dam, they developed a splendid irrigation system that watered about 25,000 acres.  Pictures of the current dam, as well as of the ancient dam, can be found at http://nabataea.net/marib.html  Information about the Sabaean civilization, which is perhaps familiar as Sheba, can be found at https://www.ancient-origins.net/ancient-places-asia/ma-rib-dam-engineering-wonder-ancient-world-torn-apart-rats-009396  This study will also be posted on the 2018 Actions and Activities Page of the Sustainable Water Resources Site at https://sites.google.com/site/sustainablewaterresources/  Tim SmithSustainable Water Resources CoordinatorGovernment Web Site, https://acwi.gov/Sustainable Water Resources Site, https://sites.google.com/site/sustainablewaterresources/
