What is meant by water drainage in soil?
Drainage refers to how rapidly excess water leaves the soil by runoff or internal drainage. Drainage can be used to describe the downward but also the upward movement of water in the soil profile. … Soil erosion and salinization are two of the most important processes of land desertification.
What is water drainage?
The removal of excess water either from the ground surface or from the rootzone, is called drainage. Excess water may be caused by rainfall or by using too much irrigation water, but may also have other origins such as canal seepage or floods.
What is water drainage called?
Surface drainage systems contain shallow ditches dug in a parallel pattern, which act as canals for run-off water. Theses ditches lead the water into the main drain to avoid water pooling and flooding. A subsurface drainage system is also known as a French drain.
Why does soil need drainage?
Good drainage ensures that the soil is properly aerated to help crops grow. If you have excess or standing water it can choke your crops and prevent growth. Drainage also reduces soil and nutrient loss from runoff and can help avoid soil erosion.

What is drainage in geography?
The flow of water through well-defined channels is known as ‘drainage’ and the network of such channels is called a ‘drainage system’. The drainage pattern of an area is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing and the periodicity of the flow.
How does drainage work?
Your home’s drainage system uses gravity to pull water through the house and outside to drain. Waste and dirty water is piped through a “Soil Stack” which in turn takes the waste through a main drain, generally located underneath the house. … Vents prevent these gases from escaping through the house.
What is main drainage?
The main drainage systems consist of deep or shallow collectors, and main drains or disposal drains. Deep collector drains are required for subsurface field drainage systems, whereas shallow collector drains are used for surface field drainage systems, but they can also be used for pumped subsurface systems.
What is good drainage soil?
Deep, loamy soil and sloping sites tend to be well drained. Soil high in clay content, depressions, or sites with high water tables, underlying rock or ‘hard pans’ (a layer of soil impervious to water) tend to not be well drained.
Which soil has best drainage?
Sandy soil drains more readily than other types of soil. Sand drains so quickly that extremely sandy soil needs to be watered more often because sand will not retain water long enough for plant roots to have good access to the moisture before it drains away. Sandy soil also lacks nutrients plants need.
What increases soil drainage?
A key practice for improving soil drainage is incorporating organic matter like compost or well-rotted manure. Organic matter improves soil structure by increasing soil aggregation which allows for more and varied pore sizes.

What are drainage features?
drainage feature means any natural or man-made structure, facility, conveyance or topographic feature which has the potential to concentrate, convey, detain, retain, infiltrate or affect the flow rate of stormwater runoff.
What is natural drainage?
Natural drainage means a drainage consisting of native soils such as a natural swale or topographic depression which gathers or conveys run-off to a permanent or intermittent watercourse or waterbody.
What are the different methods of drainage?
Methods of Drainage:
- (i) Surface Drainage:
- (ii) Sub-Surface Drainage:
- (B) Mole drains:
- (C) Vertical drainage:
- (D) Deep open drainage:
- (E) Buried drainage:
What are the benefits of drainage?
i. Drainage promotes beneficial soil bacteria activity and improves soil tilth. ii. There is less surface runoff and soil erosion on drained land.
What are advantages of drainage?
Advantages of a Drainage System
- Prevents Water Accumulation. Too much accumulated water on your lawn can lead to flooding which can in turn kill your plants. …
- Reduces Soil Erosion. Stagnant water can make soil muddy which will cause it to erode. …
- Removes Toxic Materials. When the conditions permit, flash flooding can occur.
Is Sanguineous drainage normal?
The presence of serosanguineous drainage is a normal occurrence, which usually appears during the inflammatory stage of the wound healing process and typically represents damage to capillaries.
What does Sanguineous drainage look like?
Serosanguinous drainage is thin, like water. It usually has a light red or pink tinge, though it may look clear in some cases. Its appearance depends on how much clotted red blood is mixed with serum.
What statement best describes Sanguineous drainage?
Sanguineous drainage refers to the leakage of fresh blood from an open wound. This type of drainage is bright red in color and has a syrup-like consistency.
What is drainage class 9th?
