Inundation Canal

A type of water system called an inundation or flood system uses a trench to redirect extra water from a stream during a flood. This plan can only be implemented during the monsoon season, and the water channels that are used for it are known as Inundation Canals.

These have been used for water collection in India traditionally, and by spreading and moving the water, they can also help with flood control. The water system was primarily operated by cuts in the banks of the channels, and it was shut down once the flooding was over. The water supply in the Inundation primary trench relies upon the water level in the stream as there are no headworks across the waterway. The water will be accessible just for a period on the principal trench when the water level in the stream is over the bed level of the immersion fundamental channel at its off-take point from the stream. Under the following circumstances, The Inundation Trenches may be familiar with an area:

  • If the water level in the trench remains high and consistently steady for a while When there is an early flood in the stream, Kharif harvests can be watered.
  • When the waterway experiences its final flood before the windy season ends, allowing for the flooding of the Rabi harvests. When the area to be watered is close to the trench structure a significant area won’t be lowered in the event of the worst possible flood in the stream. The soil must have sufficient self-balancing capacity to maintain the waterway’s bed and banks stable.

Benefits of Immersion Trench 

The cost of development is incredibly low for immersion channels because there is no headwork involved. The immersion trench framework has excellent manorial characteristics as a result of the water’s conveyance of debris and fine sand into the channel. There is less difficulty with waterlogging and other terrible effects of the water system because the water supply in the trench is intermittent.

Disservices of Immersion Trench

Since there is no headwork protecting the waterway, the trench must be washed away. Since the water stored in the trench is mainly accessible during floods, the water supply is not reliable. Comparatively speaking, the obligation fulfilled by immersion trench water is minimal. The inconvenience of sediment is constant. To accommodate the full need for water within a constrained time factor, the size of the trenches should be larger.

Distinguish between Inundation Canal and Perennial Canal

Canals are systems of rivers or man-made waterways used to move water or support water transportation vessels. They can also help with irrigation. It can be described as a river that doesn’t actually exist. Canals support unrestricted surface flow when the air pressure is high. Inundation canals are mostly without the building of dams, barrages, or embankments, inundation canals and perennial canals are built with the building of dams or barrages, and perennial canals are said to be removed from rivers as well as reservoirs.

A perpetual water system is a reliable and continuous water supply that is ensured the yields in accordance with the harvest’s requirements throughout the yield period.
