The Aztecs built dikes for flood control and to separate the saline water of the northern lakes from the fresh water of the southern ones. After the destruction of Tenochtitlan in 1521, the Spaniards rebuilt the Aztec dikes but found they did not offer enough flood protection. [25]
Many of the modern myths included obviously Christian references such as the murder of Abel by Cain as the reason. In Mesoamerican myth the flood was but one of several destructions of the creation — usually the first of three or four cataclysmic events, although there is some evidence that the Aztecs considered the flood to be the fourth.
Ancient Aztec paintings often depict the boat floating on the flood waters beside a mountain. The heads of a man and a woman are shown in the air above the boat and a dove is also depicted. In its mouth the dove is carrying a hieroglyphic symbol representing the languages of the world, which it is distributing to the children of Coxcox.
It also permitted them to control the level of the lake. The city also had an inner system of channels that helped to control the water. The Aztec ruler Ahuitzotl attempted to build an aqueduct that would take fresh water from the mainland to the lakes surrounding the Tenochtitlan city. The aqueduct failed, and the city suffered a major flood ...
Built along the same path as the Aztec engineered aqueducts, it was constructed using Roman architecture, reflected in its 904 arches. In completion, it reached a total length of 4663 varas, roughly 4 kilometers. In conquest times, the aqueduct supplied the city with the majority of its freshwater, however, waterborne illness was a concern.
A tunnel and later a surface drainage system diverted flood waters outside the closed basin of Mexico. Not until the late nineteenth century under Porfirio Díaz (1876-1911) was the project completed by British entrepreneur and engineer, Weetman Pearson , using machinery imported from Great Britain and other technology at a cost of 16 million ...
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...
