What is graded Bund?
Graded Bunding: Definition. AGraded bunds, graded terraces, or channel terraces are bunds or terraces that have been laid along a predetermined longitudinal grade very close to the contour but not exactly. Suitability: Bunds and bund channels are not suitable for farming operations.
What is level Bund?
If the slope is not steep and the soil's permeability is good, then absorption or level bunds can be used in areas with low rainfall. Level bunds are created along contours with the intent of holding runoff water to allow it to infiltrate into the soil.
What is compartment bunding, other than the above? Compartmental bunding is the division of a field into smaller compartments that are predetermined in size. This allows rainwater to be retained and soil erosion is prevented. Bund former is used to create the compartmental bundles. The slope of the land determines the size of the bunds.
What is a bench terrace, then?
Bench terraces are soil and water conservation measures that are used on sloped land with deep soils to retain water, and reduce erosion. They are usually constructed by filling and cutting to create a series of steps or benches. This allows water to slowly infiltrate the soil.
What is contour bunding and terrace bunding?
Terracing is a process that involves cutting wide steps around hillslopes to prevent soil erosion. Contour ploughing maintains the natural slope shape without altering it. Terrace farming alters slope shape to create flat areas that serve as a catchment area for water.

What is a river bund?
The Bund is a mile-long stretch of waterfront promenade along the Huangpu River. To the west of this stretch stand 52 buildings of various architectural styles, including Gothic, baroque, and neoclassical styles. It is often referred to as "the museum of buildings".
What is meant by contour bunding?
Contour bunding (or contour bundling), which involves the placement of lines of stones along the natural rises of a landscape, and contour farming. These techniques help to capture and hold rainfall before it can become runoff. They also inhibit wind erosion by keeping the soil…
What is the meaning of building bunds?
Bunding, also called a bund wall, is a constructed retaining wall around storage "where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as a remedial action can be taken."
For which areas construction of bunds is considered useful?
Contour bunds are recommended for areas with low annual rainfall (<600 mm), agricultural field with permeable soil and having a land slope < 6%. The major requirements in such areas are prevention of soil erosion and conservation of rain water in the soil for crop use.
What are bunds in geography?
Magic stones (or bunds) are circles of stones placed on the ground to hold water on the soil rather than letting it run quickly over the surface. Drip irrigation is where water drips slowly onto the ground from pin-sized holes in a hose lying on top of the soil.
What is stone bund?
Stone bunds are an embankment of stones constructed along the contour line to reduce or stop the velocity of water flowing down-slope, consequently reducing soil erosion (Gebremichael et al., 2005; Vancampenhout et al., 2006) (Figure 2.1).
How do bunds work?
An earth bank or soil bund can be used to: slow the movement of water, protecting streams and rivers from pollutants. slow flows during high rainfall and reduce downstream flooding. control water levels to aid raised water levels for habitat creation and restoration.
Why is terrace farming popular in the mountainous states?
Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. Terrace farming is very beneficial because it decreases the soil erosion and help to provides more space for farming.
What are the three main types of terracing?
There are three kinds of terraces (a) bench terraced farmlands; (b) sloping terraced farmland; (c) combination level terraced farmlands and natural slope land. Bench terrace is the basic type of farmland in mountains.
What are the advantages of terrace farming?
What are the benefits of a terrace system? The major benefit, of course, is the conservation of soil and water. Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.
What does terrace level mean?
The distinguishing factor between the two is that a terrace is ground-level, but it is raised from the ground around it such as being built at the edge of a hill or cliff. The word terrace gives more description as to the physical surroundings of the outdoor structure whereas a patio is on flat level ground.
How and why are terraces built?
The terraces were built to make the most efficient use of shallow soil and to enable irrigation of crops by allowing runoff to occur through the outlet. The Inca built on these, developing a system of canals, aqueducts, and puquios to direct water through dry land and increase fertility levels and growth.
Which kind of bench terrace is suitable for the steep slopes for the soil conservation process?
11. Sloping inwards bench terrace Sloping inwards bench terrace are suitable for: • Areas receiving heavy rainfall. Sloping inwards bench terrace Sloping inwards bench terrace are suitable for • It is useful for crops susceptible to water lodging. Runoff towards hillside.
What is terrace farming and how is it useful?
Terrace farming is carried out on the slopes of the mountains. Terraces are built on the slopes of the mountains to create flat lands to grow crops. Terrace farming is useful as it slows down the speed of water running down the mountains. This conserves fertile top soil.
What is gully control?
Over the years, unchecked soil erosion can lead to the formation of deeper and deeper gullies. If it is a small gully, vegetation can be planted in strips across the gully to slow the velocity of water, trap silt, and prevent further erosion.
Why is terrace farming done in hilly areas?
The practice of forming stepped terraces along the slopes of mountains for agricultural practices is known as terracing. It prevents soil erosion and rainwater runoff. - Helps in the conservation of soil. Decreased soil erosion results in better and more nutritious soil for crops.
What is Zing terracing?
(i) Zing terracing is adopted in 3-10 per cent land slope. (ii) It is constructed in medium to deep soils in high rainfall areas. (iii) The aims of constructing zing terracing is: (iv) To cut down the length of slope. (v) To harvest the runoff from upper areas for the benefits of crops grown in lower areas.
