What do you mean by water logging?

What do you mean by water logging?

Waterlogging is the natural flooding and over-irrigation that brings water at underground levels to the surface. As a consequence, displacement of the air occurs in the soil with corresponding changes in soil processes and an accumulation of toxic substances that impede plant growth.

What causes water logging?

Heavy clay soils such as black cotton soils are prone to water logging, as they hold moisture for long periods. Also, soils prone to surface sealing cause temporary water logging. Seepage and interflow from other water bodies e.g. lakes, rivers and shallow aquifers can cause water logging of adjacent lands.

What is water logging in Pakistan?

Waterlogging: Waterlogging are the problem mainly caused by seepage of water due to problems in the canal system of Pakistan. There is no scientific methods for irrigation purposes and rough surface runoff and gravitational drainage. ”

What is water logging and salinity in Pakistan?

In Pakistan, more than 6.3 million hectares have been damaged by salinity and 1 million hectares are damaged by waterlogging. The Indus River Basin suffers from salinity and waterlogging due to inadequate water management practices, poor surface, and subsurface drainage, water seepage from canals, etc.

What is water logging and its effects?

An artificial land is said to be water-logged when its productively gets affected by the high water table. The productivity of land may become affected when the root zone of plants gets flooded with water, and thus become ill- aerated.

What is water logging in agriculture?

Waterlogging is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In agriculture, various crops need air (specifically, oxygen) to a greater or lesser depth in the soil.

What is meant by water logging and salinity?

Waterlogging refers to the saturation of soil with water. In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water.

What is water logging in water resources engineering?

When the water table rises to such heights that the soil pores in the root zone become saturated, thus displacing the air, the land is said to be water logged. Waterlogging is happened when the soil is so filled or soaked with water that caused the roots of the plant to rot.

What is water logging in civil engineering?

What is Water Logging? When water table reaches upto or near to ground level then such a land is called as water logged. Due to water logging productivity of land gets affected. Water logging can be also referred as saturation of soil with excess of water.

What is water logging 10?

When too much water is given to the soil, it becomes wet. Water accumulates around the plant. This is called water-logging.

What is water logging Upsc?

Waterlogging is simply the saturation of soil with water, either temporarily or permanently. When there is too much water in an area, the soil is unable to absorb the water as it should ordinarily. It can also happen when the water table rises to the extent that the soil pores in the crop root zone.

What is water logging in city?

Urban waterlogging refers to the phenomenon when there is rainstorm or short time heavy rain, which surpasses the capacity of the urban drainage system, and then waterlogging disaster happens.

What does water logging mean?

Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture. Waterlogging (archeology), the exclusion of air from an archeological site by groundwater , preserving artifacts.

What does water logging and salinity mean?

The water on reaching the surface evaporates and the salts are deposited on the surface, rendering the land unsuitable for farming. The rise of the water-table to the surface level is called water logging and the appearance of salty patches is called salinity. Management of Water Resources: Ther is a scarce resource in Pakistan.

What is a water log?

Water Log is meant to track a user’s daily water consumption. To begin tracking tell Water Log to add/log x ounces of water. This will add the amount to the daily running total. To check on your current performance, ask Water Log how much you have drank/consumed today.
