Many of the 11 ancient Roman aqueducts built between 312 BC to 226 AD, carrying water from Tivoli approximately 70 Km away . The longest waterway, Anio Novus, is almost 97 km.
To get an even, gentle slope so that the water would not stand still. The Romans laid underground pipes and covered the landscape with Siphon. Workers dig trenches, take cover underground and build drainage networks to carry water from lakes or ponds to Rome. Pipes were usually made of concrete, but if the government allocated enough money, they were also made of lead (in 300 BC, tin was very expensive). When the pipes were supposed to cover the valley, Siphon was made underground. The Siphon were made in such a way that it created a instant slope, which is why the water fell so quickly and had enough momentum to rise. The Siphon is included in the toilet flush mechanism.
However, the problem with Siphon is its price. Since the water needs to be faster, it really need a lead pipe to work effectively. This led to the use of arches that most of us have come to associate with the Roman aqueduct. If Siphon is not practical for some regions arches were constructed that ran through the valley carrying pipes within it.
Sedimentation tanks were used to remove impurities from water. In other sections, access points were carved into the system so maintenance workers could access the pipes. One way the engineers facilitated maintenance was by running two pipes alongside each other and diverting water between the two so men could get inside one pipe at a time.
Recent Excavation Was made In Delikkemer to Patara Walk
In the eastern part of the Xanthos Delta, a right turn (towards the ocean) just before the main road to Kalkan bends to a dirt road where old buildings immediately appear on the horizon. Start from here by pulling up and down the walls leading to the Roman aqueduct at Patara. Climb up to admire the intact pipelines, carved into the rocks, necessary to retain water as you pass through the collapse of this circle.
Turn right along the western wall and exit the black road. Turning north, end the route at the corner of the route following the next waterway. Elegant trails run along slopes, past fields, pine forests and meadows, and along red and white trails. Outside the forest, you can see the Xanthos delta, Patara ruins and the sea.
My partner and I stumbled over here different web page and thought I might check things out.
I like what I see so now i’m following you.
Look forward to going over your web page again.
