What is waterlogging? In irrigation engineering


It is defined as the productivity of cultivation, the land is decreased due to an increase in the water on the table in the land. The water table is increased and the root zone of the plants is full of water that can’t get the required energy from the plants so the production of the crops decreases.

Waterlogging is one of the big problems in irrigation engineering. Because due to this problem decreases the productivity of crops. In fact, the product of the crops decrees when the root zone of the plants gets flooded with water.

Definition of Water Logging

At the point when the conditions are made to such an extent that the yield root zone gets denied of legitimate air circulation because of the presence of exorbitant dampness or water content, the plot is supposed to be waterlogged. 
To make such conditions it isn’t generally essential that under groundwater table ought to enter the harvest root zone. Once in a while regardless of whether the water table is beneath the root-zone profundity the slim water zone may stretch out in the root-zone profundity and makes the airflow unimaginable by filling the pores in the dirt.

Causes of waterlogging

  • Intensive irrigation
  • Seepage from canal
  • Seepage of water from adjoining highlands
  • Impervious obstruction
  • Inadequate natural drainage
  • Excessive rain
  • Submergence due to floods
  • The improper joining of the pipeline

Effect of waterlogging

  • Decrease crop yields
  • Inadequate circulation of the air in the root zone of crops
  • Soil temperature decreases due full of water at the root zone
  • Delay in a cultivation operation
  • Breeding of insects and misquotes
  • Growth of unwanted plants
  • The salinity of topsoil increase

Central issues 

Waterlogging happens when roots can’t breathe because of abundant water in the dirt profile. 
Water doesn’t need to show up on a superficial level for water logging to be a likely issue. 
Improving waste from the immersed enclosure can diminish the time frame at which the yield attaches are exposed to anaerobic conditions. 
While raised beds (see Raised Bed Cropping actuality sheet) are the most escalated the executive’s technique, they are additionally the best at improving waste. 
Waterlogged soils discharge expanded measures of nitrous oxide (N2and, an especially harmful ozone-depleting substance. 

What is the type of Waterlogging?

Riverine Flood Waterlogging 

It is a kind of waterlogging that happens during the blustery seasons, where floods come to close terrains from the waterway since it conveys an overabundance of water. The water is waterlogged in the land and prompts the passing of various plants or harvests. 

Oceanic Flood Waterlogging 

As the name proposes and getting from the previously mentioned type, oceanic flood water logging is portrayed by oceanic waters spreading onto close-by grounds and causing it.
This especially can happen when there are outrageous climates influencing the seas, like typhoons and torrents. 

Occasional Waterlogging 

Now and then during the stormy seasons, spillover water may gather into the swamps and sorrows, prompting waterlogging. 

Perpetual Waterlogging 

This happens when profound water or marshes get water and the overflow and leakage water spreads onto adjoining lands, causing lasting water logging. 

Sub-soil Waterlogging 

It is another kind of waterlogging that happens when water tables ascend high, particularly during the blustery seasons, causing water logging.

Settling waterlogging 

Waste can be enhanced in numerous destinations and is the main interesting point once a water logging issue has been distinguished. Choices may differ from shallow surface channels (ie. Spoon-and ‘W’- channels) to more concentrated waste utilizing wide-divided wrinkles, to the serious seepage type of raised beds (see Raised Bed Cropping truth sheet). The proficiency of surface waste expansions in a specific order as does the level of the board. Counsel your nearby guide for additional exhortation. 

Indications and causes 

The absence of oxygen in the root zone of plants causes their root tissues to deteriorate. Generally, this happens from the tips of roots, and this makes roots show up as though they have been pruned. The result is that the plant’s development and improvement slowed down. On the off chance that the anaerobic conditions proceed for an impressive time, the plant, in the end, bites the dust. 
Regularly, waterlogged conditions don’t keep going long enough for the plant to bite the dust. When a water logging occasion has passed, plants recommence breathing. However long soil conditions are clammy, and the more seasoned roots near the surface permit the plant to endure. Notwithstanding, further water logging-prompted root pruning or potentially dry conditions may debilitate the plant to the degree that it will be inadequately gainful and may at last bite the dust. 
Numerous ranchers don’t understand that a site is waterlogged until water shows up on the dirt surface. Notwithstanding, by this stage, plant roots may as of now harmed and yield potentially seriously influenced.

Preventive measures for waterlogging

Prevention of waterlogging is the most important factor in irrigation engineering to increase the productivity of crops. The followings are the main points to prevent waterlogging:

  1. The lining of the channel and watercourse.
  2. Reducing the intensity of irrigation.
  3. Introducing crop rotation.
  4. Providing interception drains.
  5. The provision of an effective drainage system.
