Roman dams

Roman technology is the collection of techniques, skills, methods, processes, and engineering practices utilized and developed by the civilization of ancient Rome (753 BC – 476 AD).The Roman Empire was a technologically advanced civilization of antiquity. The Romans incorporated technologies from the Greeks, Etruscans, and Celts. The technology developed by a civilization is limited by the available sources of energy, and the Romans were no different in this sense. Accessible sources of energy determine the ways in which power is generated. The main types of power accessed by the ancient Romans were human, animal, and water.

With these limited sources of power, the Romans managed to build impressive structures, some of which survive to this day. The durability of Roman structures, such as roads, dams, and buildings, is accounted for the building techniques and practices they utilized in their construction projects. Rome and her surrounding area contained various types of volcanic materials, which Romans experimented with the creation of building materials, particularly cements and mortars.  Along with concrete, the Romans used stone, wood, and marble as building materials. They used these materials to construct civil engineering projects for their cities and transportation devices for land and sea travel.

Dams

The Romans built dams for water collection, such as the Subiaco Dams, two of which fed Anio Novus, one of the largest aqueducts of Rome. They built 72 dams in just one country, Spain and many more are known across the Empire, some of which are still in use. At one site, Montefurado in Galicia, they appear to have built a dam across the river Sil to expose alluvial gold deposits in the bed of the river. The site is near the spectacular Roman gold mine of Las Medulas. Several earthen dams are known from Britain, including a well-preserved example from Roman Lanchester, Longovicium, where it may have been used in industrial-scale smithing or smelting, judging by the piles of slag found at this site in northern England. Tanks for holding water are also common along aqueduct systems, and numerous examples are known from just one site, the gold mines at Dolaucothi in west Wales. Masonry dams were common in North Africa for providing a reliable water supply from the wadis behind many settlements.

The Romans built dams to store water for irrigation. They understood that spillways were necessary to prevent the erosion of earth-packed banks. In Egypt, the Romans adopted the water technology known as wadi irrigation from the Nabataeans. Wadis were a technique developed to capture large amounts of water produced during the seasonal floods and store it for the growing season.

The Romans also constructed the world’s first arch dam in the Roman province of Gallia Narbonensis, now modern-day southwest France, in the 1st century BCE

The dam was about 12 metres (39 ft) high and 18 metres (59 ft) in length. Its radius was about 14 m (46 ft), and it consisted of two masonry walls.

The Romans successfully developed the technique further for a larger scale.

Italian planes of the Second World War

 

 

The first is an extraordinary fighter jet of aerial supremacy, the FIAT G55 Centauro and the second is a four-engine strategic bomber, the Piaggio P 108. The first arrived too late and the second too sophisticated for the limited possibility of finding materials of the highest quality and too much futuristic for the industrial capacities of the time. Both however produced in very limited numbers. They were extremely competitive, so much so that the Germans considered the FIAT G55 to be the best piston engine fighter aircraft in the world (This clarification is a must since they had already put the Messershmitt 262 into production, an arrow wing aerator that it was the best fighter ever) and the Piaggio P108 was a four-engine comparable to the American Boeing B 17. The strong limit is summarized in the numbers produced, the USA produced something like thirteen thousand B 17, the famous “Flying Fortresses” and the Kingdom of Italy only about thirty P 108, a production difference of about one to four hundred. The only aircrafts to have posed a serious threat also to the specimens produced were the Macchi MC 202 fighter and the Savoia Marchetti SM 79 bomber three-engine, born as a civil aircraft, converted into a bomber during the Spanish War and discovered in the vocation of torpedo bombers towards the middle of the Second World War.

The HD9 tractor stands out for the strength and reliability it guarantees in off-road conditions.

It is used particularly for oversize loads (trailers, half-trailers or dual-use) in the oil and extraction sectors, thanks its ability to adapt to difficult and adverse weather and terrain conditions, from the heat of the African deserts to the ice of Alaska.

Available in a 2 or 3-axle and tridem version, it offers a combined total weight above 200 tons.

 

Robust and reliable, but also drivable and easy to maintain to be ready to tackle any route, on any type of terrain, in any weather conditions, whenever.

CANAL: Naviglio della Martesana

Italian and English version

The Naviglio della Martesana, definitively completed in 1496 under the guidance of Ludovico il Moro, flows from Trezzo sull’Adda to Milan for a total length of 38 km. The route flanks the ancient Roman road (the present SS 11 Padana Superiore) which passed the Adda with two branches: to Vaprio and Cassano.

The irrigation of the land located above the band of fountains was for a long time the prevalent use of the canal, so much so that at first the navigation was limited to two days a week; at the same time as the improvement of the agricultural structure thanks to irrigation, a remarkable flowering of stately villas took place in the Baroque period, aimed at enjoying the convenience of traveling on water and controlling the lands owned. The irrigation function of the Martesana did not have the ordering effects of the territory comparable to the Naviglio Grande, but certainly, more than the Naviglio Grande, it marks the clear border between the dry plain in the north and the irrigated plain in the south.

 

 

Il Naviglio della Martesana, completato definitivamente nel 1496 sotto la guida di Ludovico il Moro, scorre da Trezzo sull’Adda a Milano per una lunghezza totale di 38 km. Il percorso affianca l´antica strada romana (l´attuale SS 11 padana superiore) che passava l´Adda con due rami: a Vaprio e a Cassano.

L´irrigazione dei terreni situati al di sopra della fascia dei fontanili fu a lungo l´uso prevalente del canale, tanto che in un primo tempo la navigazione era limitata a due giorni alla settimana; contestualmente al miglioramento della struttura agraria grazie all’irrigazione, si produsse in epoca barocca una notevole fioritura di ville signorili, volte a godere della comodità del viaggio sull’acqua e controllare le terre di proprietà. La funzione irrigua della Martesana non ha avuto effetti ordinatori del territorio paragonabili al Naviglio Grande, ma certamente, più del Naviglio Grande, segna il confine netto tra pianura asciutta, a nord, e pianura irrigua, a sud.

FIAT SUV Toro

The FCA follows the example of other car manufacturers and “rides” the vein of SUVs with an appearance inspired by coupè, those tall models with muscular shapes, but with a streamlined appearance with a low and sloping roof.

 

 

Presented at the San Paolo Motor Show, the Fiat Fastback prototype is a racy and sporty-looking SUV.
