What is drainage basin and its characteristics?

A drainage basin is an area of land where water from rain or snow melt drains downhill into a body of water such as a river, lake, wetland or ocean. The drainage basin includes both the streams and rivers that convey the water as well as the land surface from which water drains into those channels.

What are the classification of drainage?

While there are more than two types of drainage systems employed in agriculture, there are two main types: (1) surface drainage and (2) sub-surface drainage.

How do you describe the drainage of an area?

Definition: A drainage area is the total surface area, upstream of a point on a stream, where the water from rain, snowmelt, or irrigation which is not absorbed into the ground flows over the ground surface, back into streams, to finally reach that point.

What are the five types of drainage networks and their characteristics?

Drainage patterns
  • Dendritic drainage pattern. Dendritic drainage systems (from Greek δενδρίτης, dendrites, “of or like a tree”) are not straight and are the most common form of the drainage system. …
  • Trellis drainage pattern. …
  • Rectangular drainage pattern. …
  • Radial drainage pattern. …
  • Deranged drainage pattern.

What is the importance of drainage?

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.

What are the 4 different types of drainage?

What are the 3 types of drainage?

The types of drainage systems will allow you a better comprehension of their roles and how they work together.
  • Surface Drainage System. Surface drainage systems remove excess water from the land’s surface through channels or ditches. …
  • Subsurface Drainage System. …
  • Slope Drainage System. …
  • Downspouts and Gutter Systems.

What is drainage and its types?

Many areas have some natural drainage; this means that excess water flows from the farmers’ fields to swamps or to lakes and rivers. Natural drainage, however, is often inadequate and artificial or man-made drainage is required. There are two types of artificial drainage: surface drainage and subsurface drainage.

What are the types of drainage in agriculture?

The two general types of drainage practices are surface and subsurface. Surface drainage is the removal of excess water from the soil surface. Subsurface drainage is the removal of water from the soil profile.

What are the two main types of drainage system?

There are two main types of drainage system options: surface drains and french drains. Surface drainage systems consist of a few ground-level areas drains that are connected to PVC piping. When it rains, water flows down the drains, into the piping, and is transferred away from the house.

What are the methods of drainage?

The conventional engineering-based techniques most commonly used to drain excess water from land are: surface drainage, horizontal subsurface drainage and vertical subsurface drainage.

What are effects of drainage?

Poor drainage caused by the shape of the landscape or inadequate drainage systems can damage buildings and move soil from where it’s needed to where it causes trouble. The effects of poor drainage systems extend beyond single properties and can have an impact on roads, waterways, and health.

What is main drainage?

The main drains are usually run under the street and connections to them often involve digging roadworks to gain access, the kind of event that requires traffic control and the like. Such works are expensive but, in the great scheme of things, they are still usually cheaper than the alternatives.

What are components of drainage system?

Drainage systems, particularly in the minor system network, might include pipelines, open channels, natural surface channels and canals. The major drainage system would almost certainly include open channels and natural watercourses within an urbanized (or urbanizing) catchment.
