over 500,000,000 gallons
1. Gates controlled how much water flowed from the river. 2. Main canals led from the river. They sloped down gently to keep the water flowing. 3. Medium-sized branch canals led away from the main canals. 4. Small feeder canals led directly to the fields. SHORTER ANSWER: Farmers built canals to carry water from the rivers to their fields. (irrigation) Built dams to hold back excess water during floods. Silt in water clogged the canals.

seasonal canals are those canals that are not having water throughout the year
Canals can connect bodies of water, usually rivers.
Inundation canals are canals that are linked to large rivers. Perennial canals are the canals which are linked with dams. Inundation canals provides water only when rivers are flooded while perennial canals supplies water all the time.
perennial canals : They are linked to dams and barrages to provide water throughout the year and they irrigate a vast area.Inundation canals : long canals taken off from large rivers are called inundation canals. They receive water when the river is high enough and especially when it is in flood
Venice, in northern Italy, is built above water, and much of the city has canals instead of streets.
its because of the water
There are two reasons why we build canals:1) We use them as aquaducts, or as a water supply, as you may call it.2) We also use them for transportation. Some people in other countries may have to get around in water canals. You may also think of it as in Rome. They have water canals for boat rides and/or transportation.
It is how people got around on water from 1790-1855 which was known as the age of canals.

lined are man-made and lined with cement and stone. Unlined are natural water ways (rivers, etc.) ,or hand/machine dug canals that are re-dug and bottom drudged regularly to keep them passable
