What are the effects of drainage on agriculture?
ADVERTISEMENTS: “Drainage (agriculture) is saturation of removal of excess water from the field to ensure a favorable salt balance in the soil and water table optimum for crop growth and development”. Drainage aims at maintenance of soil moisture within the range required for optimum crop growth.
How does Drainage affect soil formation?
Drainage promotes beneficial soil bacteria activity and improves soil tilth. ii. There is less surface runoff and soil erosion on drained land.
How does Drainage improve soil for farming?
Drainage ensures that the soil is properly aerated. If you have excess or standing water it can choke your crops. Drainage reduces soil and nutrient loss from runoff and can help avoid soil erosion. Drainage on hill slopes helps to reduce the risk of soil slippage.
How drainage is effective for crops?
Drainage results in the lowering of water tables by removal of water through ditches or tubes (figure 17.14). The main benefit is the creation of a deeper soil volume that is adequately aerated for growth of common crop plants.
What is the necessity of road drainage?
Highway drainage is used to clear surface water from the highway. . Roads need to be well drained to stop flooding, even surface water can cause problems with ice in the winter. Water left standing on roads can also cause maintenance problems, as it can soften the ground under a road making the road surface break up.
What are the different types of drainage systems?
There are two types of artificial drainage: surface drainage and subsurface drainage.
- 6.2. 1 Surface drainage. Surface drainage is the removal of excess water from the surface of the land.
- 6.2. 2 Subsurface drainage. Subsurface drainage is the removal of water from the rootzone.
What are the 3 types of drainage?
Understanding the Types of Drainage Systems
- Surface Drainage System. Surface drainage systems remove excess water from the land’s surface through channels or ditches.
- Subsurface Drainage System. Subsurface drainage systems are implemented beneath the top layer of soil.
- Slope Drainage System.
- Downspouts and Gutter Systems.

What is a natural drainage?
Natural drainage systems (NDS) are an innovative alternative to traditional stormwater management systems. It is a series of stair- stepped natural pools that slow the flow of stormwater, reduce flooding, and filter pollutants before they reach Pipers Creek.
What is the most common type of drainage pattern?
dendritic drainage pattern
What is main drainage pattern?
The drainage pattern marked by right-angled bends and right-angled junctions between tributaries and the main stream is known as rectangular drainage. It differs from the trellis pattern in so far as it is more irregular and its tributary streams are neither as long, nor parallel as in trellis drainage.
How many drainage patterns are there?
III Types of Drainage Pattern. Zernitz (1932) summarized seven major types of drainage plan: dendritic, trellis, rectangular, radial, annular, parallel and irregular.
What is drainage pattern give example?
A drainage pattern which looks like tree branches with lots of twigs is known as Dendritic drainage pattern. For example, the rivers of northern plain. Radial drainage patterns form when rivers originate from a hill and flow in all directions. For example, the rivers originating from the Amarkantak.
What is the most important factor for drainage pattern development?
In a drainage basin, a number of factors such as topography, soil type, bedrock type, climate and vegetation cover influence input, output and transport of sediment and water (Charlton, 2008). These factors also influence the nature of the pattern of water bodies (Twidale, 2004).
What is the difference between drainage system and drainage pattern?
What is the difference between drainage pattern and drainage system? Drainage pattern means spatial arrangement and form of drainage system in terms of geographical shapes in the areas of different rock types. There are different patterns, such as the trellis pattern, the dendritic pattern, and so on.
What is pinnate drainage pattern?
[′pi‚nāt ′drā·nij] (hydrology) A dendritic drainage pattern in which the main stream receives many closely spaced, subparallel tributaries that join it at acute angles; resembles a feather in plan view.
Why are there different types of drainage pattern?
They are governed by the topography of the land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. The pattern of tributaries within a drainage basin depends largely on the type of rock beneath, and on structures within that rock (folds, fractures, faults, etc.).
Which type of drainage pattern would you expect on a shield volcano?
Radial patterns form around isolated mountains (such as volcanoes) or hills, and the individual streams typically have dendritic drainage patterns.
