Cornalvo Dam in Spain, erected in the 1st–2nd century AD Lake Homs Dam in Syria, erected in 284 AD (photographed 1921). This is a list of Roman dams and reservoirs.The study of Roman dam-building has received little scholarly attention in comparison to their other civil engineering activities, [1] even though their contributions in this field have been ranked alongside their expertise in ...
Once built, the water stored behind the dam raises the water table and is then extracted with wells. A sand-storage dam is a weir built in stages across a stream or wadi. It must be strong, as floods will wash over its crest. Over time, sand accumulates in layers behind the dam, which helps store water and, most importantly, prevent evaporation ...
The history of water supply and sanitation is one of a logistical challenge to provide clean water and sanitation systems since the dawn of civilization. Where water resources, infrastructure or sanitation systems were insufficient, diseases spread and people fell sick or died prematurely. Astronaut Jack Lousma taking a shower in space, 1974
Ancient and medieval civilizations needed and used water to grow the human population as well as to partake in daily activities. One of the ways that ancient and medieval people gained access to water was through qanats, which were a water duct system that would bring water from an underground source or river source to villages or cities.

The Visconti Bridge at Valeggio sul Mincio is a medieval viaduct over the Mincio River built at the end of the 14th century by Gian Galeazzo Visconti, Duke of Milan.Initially conceived as a fortified dam to divert the Mincio water flowing to Mantua, it has served as a bridge since then. [1]
The dam was the middle and highest in a series of three dams. [7] The structural remains had already been carried off for new construction in the city of Subiaco in the late Middle Ages. The masonry of the dam had a reconstructed height of 40 metres (perhaps up to 50 metres high), was 13.5 metres thick and a length of 80 metres across the top.
A dam with a sluice is created across a suitable tidal inlet, or a section of river estuary is made into a reservoir. As the tide comes in, it enters the mill pond through a one-way gate, and this gate closes automatically when the tide begins to fall. When the tide is low enough, the stored water can be released to turn a water wheel.
The dam is located in Tiruchirappalli district, [1] [2] 15 km from Tiruchirapalli and 45 km from Thanjavur. [3] [4] [5] It is the fourth oldest water-diversion or water-regulator structure in the world and the oldest in India that is still in use. [6] [7] Because of its spectacular architecture, it is one of the prime tourist spots in Tamil Nadu.
