Hi
Most innovations are inspired by the life of animals and dams are also inspired by structures that made by beavers in rivers
Kind regards
This space does not allow us to quote the history of the construction of dams.
The first is the legendary kingdom of Sheba whose splendor of their queen is famous in the Bible at the time of SOLOMON. In this kingdom, dams existed at EDRAA, ADSHMA, and near Marib, the capital. Not far from this city existed by far the most important work, the SUDD AL ARIM dam on the Dhana wadi, built around 750 BC. It consisted of an earth embankment of about 4 m high and 600 m long. It was not built at the narrowest point of the river, to avoid flooding and had on each bank of large drainage works in excellent masonry. Around 500 BC, this dam was raised to 7 m and again to 14 m in the year 325 AD. The successive elevations were probably due to the sedimentation of the reservoir which reduced the available capacity, as well as to the increase in water requirements at the rate of the increase in populations. Profiles successive works were triangles, the upstream and downstream facings being inclined at 45 °. The upstream facing was covered with masonry jointed with mortar. So for over a thousand years,
this work was the basis of agriculture and means of existence in the plain of Marib located in the east. After a first rupture in the 5th century, the dam was probably destroyed around 575.
This event is related in the Quran (Sura 34, Verses 14 and following) in the following terms:
“The inhabitants of Saba had 2 gardens crossed by a stream. We said to them: Enjoy the blessings of heaven. This valley is delicious. Be grateful ”. “They gave up worshiping the Lord. We unleashed the heaped waters of a torrent against them. Their submerged and destroyed gardens produced only bitter fruits, tamarisks and nabs ”
Thank you Professor Bachir Achour for your great information;
We hope that ALLAH will restore our lost dignity.
In ancient civilizations, dams were designed through the experiences of farmers in order to control water and store water during the rains and benefit from them during the drought period.
The Ma'rib Dam is historical and ancient in Yemen.
I am agree with Prof Bachir Achour.
