What is difference between canal and drain?
Following are the points of comparison between canal and drains….Comparison between canals and drains.
| Drain | Canal | |
|---|---|---|
| Losses | Mostly there are seepage and evaporational losses. | Evaporational losses are low but there are seepage losses in unlined canals. |
| Side slopes | No definite side slopes. | Side slope is 1:1 to 2:1 in cutting and upto 3:1 in filling. |

What is the difference between contour canals and watershed canals?
Contour canals are distinguished by the meandering course. They can increase the risk of erosion if not properly established. A Watershed is a secure area whose runoff drains into any water substance. The watershed canal aligns with any natural watershed (ridgeline). That’s why it is also known as the ridge canal.
What is the difference between a navigation and a canal?
A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal is a channel that cuts across a drainage divide, making a navigable channel connecting two different drainage basins .
