What is a gully girl?

What is another word for Gully?
SYNONYMS FOR gully 1 gulch, gorge, defile, watercourse.
What is gully erosion in simple words?
Gully erosion is the removal of soil along drainage lines by surface water runoff. Unless steps are taken to stabilise the disturbance, gullies will continue to move by headward erosion or by slumping of the side walls.
How are gullies formed?
Gullies are permanent erosional forms that develop when water concentrates in narrow runoff paths and channels and cuts into the soil to depths that cannot be smoothed over by tillage any more.
How deep is a gully?
A gully is a landform created by running water, eroding sharply into soil or other relatively erodable material, typically on a hillside. Gullies resemble large ditches or small valleys, but are metres to tens of metres in depth and width.
Where are gullies located?
A gully can be found on hillsides or mountainsides where spring runoff may carve channels into the soil.
What are the four stages of gully development?
A gully develops in three distinct stages; waterfall erosion; channel erosion along the gully bed; and landslide erosion on gully banks. Correct gully control measures must be determined according to these development stages.
How do you stop gully erosion?
Cropping methods to reduce erosion include cropping perpendicular to the slope, strip cropping, no-till, and diverse crop rotation. Cropping perpendicular to slopes reduces the chance of gully formation. Strip cropping with contouring slows the velocity of water on erosive soils.
What is a gully head?
Gully heads are the vertical faces at the top of gullies. They actively erode and move upslope, driven by run-off water from above the gully head.
What is the shape of gully?
The shape of gully, thus formed, is of V-shape and usually have sloping heads and sides. As scouring progresses, the gully becomes longer, deeper and wider. However, the extension in length is usually much faster than the widening of the gully bemuse more volume of runoff over the gully head than over the sides.
What is smaller than a gully?
A ravine is defined as a small, narrow, and deep depression, smaller than a valley, and larger than a gully (Bates and Jackson, 1984). Both grow by head cutting. Ravines can often be identified using a combination of terrain attributes, including slope, profile curvature and flow accumulation.
What is created to prevent 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. Dams can also be constructed using loose boulders. Gabions are wire woven baskets filled with stones, and can be placed across the gully as shown in the picture.
How can we prevent gullies?
Diversion of surface water above the gully area Diversions constructed above the gully area direct run-off away from gully heads, and discharge it either into natural waterways or vegetated watercourses, or onto rock outcrops and stable areas which are not susceptible to erosion.
How do you fix Gully?
- divert surface water from the gully using well-engineered surface water earthworks.
- stabilise the eroding gully head.
- shape the gully walls.
- fence the gully.
- encourage grass and other groundcover vegetation growth to help stabilise the gully floor; do not allow shrubs and trees to grow in the gully.
What is gully treatment?
Gully treatment is the stabilization of active gullies by vegetative or structural measures or a combination thereof.
What is gully plugging?
A check dam (or also called gully plug) is a small, temporary or permanent dam constructed across a drainage ditch, swale, or channel to lower the speed of concentrated flows for a certain design range of storm events and to conserve soil moisture.
