In the alignment of an - irrigation channel wherefrom offtakes have to...
The best alignment of off-taking channel is that in which the off-taking channel makes zero angle with the parent channel initially and then separates out in transition. The depth of water should always be such that off take channel runs full. The transitions should be properly designed, so as to avoid accumulation of silt. The transition can also be used as metering flume. Thus depth, slope and width will be the correct order of preference of parameters.

Decreasing order of preference of irrigation channel parameters:
In the alignment of an irrigation channel, it is important to provide offtakes at regular intervals. To achieve this, changes in certain channel parameters are made use of. The correct sequence of the decreasing order of preference for these parameters is depth, slope, width.
1. Depth:
The depth of the irrigation channel is the most important parameter when it comes to providing offtakes at regular intervals. A deeper channel allows for more water to flow through, providing a sufficient water supply to the offtakes. By increasing the depth of the channel, the flow capacity is increased, ensuring an adequate distribution of water to the offtakes.
2. Slope:
The slope of the irrigation channel is the next important parameter to consider. A steeper slope helps in maintaining a constant flow velocity and prevents sedimentation. It allows the water to flow smoothly and efficiently towards the offtakes. A gradual slope might result in slow or stagnant water flow, leading to reduced efficiency of the irrigation system.
3. Width:
The width of the irrigation channel is the least important parameter among the three. While it does play a role in determining the flow capacity of the channel, it is relatively less significant compared to depth and slope. A wider channel can accommodate a larger volume of water, but if the depth and slope are not appropriate, it may not effectively distribute water to the offtakes.
Conclusion:
In summary, the correct sequence of the decreasing order of preference for the parameters in the alignment of an irrigation channel is depth, slope, and width. Depth is the most important parameter as it directly affects the flow capacity and water supply to the offtakes. Slope ensures a constant flow velocity and prevents sedimentation, while width plays a relatively less significant role in the efficient distribution of water.
