Difference of Barrage and Dam in function
Difference between barrage and dam in Structure
Difference between a Canal and a Dam
So fellows the update is here – I have been recently emailed by one of my friend who is asking that what is the “difference between a between a canal and a dam”
So from definition point of view; a Dam is actually constructed to obstruct the flow of river water with purpose of either creating a reservoir, generating electricity, recreational and irrigation purpose.
And as for the canal; a canal is a water course which is constructed by excavating and maintaining suitable level for water to flow from reservoir to the area to be irrigated.
Dam and canal can actually be taken as a system for irrigation. But in run of river hydro-power projects where divided fall of water is used for power generation; the canal is constructed to embrace the diverted river water to the tunnel and finally to the power house turbines.
According to dynapac – the famous earth compaction machinery manufactures – Both dams and canals are designed on a fine grained, non-permeable core or lining.
For the proper support of the fine material and to stay in position, the core of a dam requires strong shoulders to withstand the massive water pressure, and a canal lining needs a strong base underneath as well as erosion protection on top to prevent the flowing water eroding the fine material.
