a deep, steep-sided cut formed by a temporary stream. It forms on elevated plains or on hills that are composed of loose, easily scoured rock and on the sides of ravines and gulches. It may be up to several kilometers long, with a width and depth of dozens of meters. Gullies are most widespread in the European USSR in the forest-steppe and steppe zones (for example, in the Central Russian Upland, Volga Upland, Volyn’ Hills, and Po-dol’e Upland) and in Middle Asia (Fergana). In other countries they are found in the loess areas of China, in a number of regions in the United States, and in tropical countries.

Gullies cause great damage chiefly to agriculture by breaking up and destroying fields. Farming practices that eliminate or reduce surface runoff and promote moisture retention on the fields are effective in preventing gully erosion. They include crop rotation, contour farming, broken ridging, slotting, strip farming, the creation of perennial-grass buffer strips along the contour, the leveling of scours, and the planting of water-absorbing forest belts horizontally along sloping lands.

On land with developing gullies, hydraulic engineering works are built and forest reclamation methods are also used. The hydraulic engineering structures include water-retaining embankments, terraces, drainage ditches, dams, chutes, overfalls, and retaining walls. The forest reclamation methods include the planting of shelterbelts around gullies and ravines, as well as afforestation and regrassing of the sides and floors of gullies. These measures prevent the development of gullies. Gullies are now sometimes flattened and then sown with grass.

Dom Proud, Telford & Wrekin Council's service delivery manager for highways, transport and engineering services, said: "To find and clean all of the 33,000 plus gullies in 12 months is a huge undertaking.
Gullies collect and remove surface water and Wrexham Council has cut how often they are unblocked from twice a year to once.
Once water seeps into this loose material, lateral seepage occurs, accompanied by underground piping, scouring and tunnelling, and finally, the top layer of the soil collapses, exposing huge gullies. The end result is the formation of huge gullies that continue deepening and widening due to this loose material.
Before the current rains, villagers could walk their animals along footpaths across the gullies but this is not possible anymore.
Floodwater on the first gully has also started to rise, meaning, residents living in the middle of the two gullies would be trapped in the event of the massive lahar flow.
These findings, detailed in a study published in the ( Geophysical Research Letters , would now allow scientists to narrow their theories about how the Martian gullies form.
This formula was obtained from data collected from a large number of debris flow gullies located in the southwest region of China; this reflected the relationship between the percentage of clay particles in the debris flow (< 0.005mm) and the density of the debris flow.
These gullies are different from (and much larger than) the occasional, seasonal trickles of salt-infused water seen elsewhere on the surface, which create the so-called recurrent slope lineae (S&T: Jan.
In the gullies known as "The Horse" these are best fished on a slightly larger ebb tide and fish well with a very slight swell, creating white water in the surrounding area.
It has cost Telford & Wrekin Council PS500 to make the gullies safe but the council is expect to foot further costs of PS2,100 to permanently replace the missing gully grates and frames.
NASA's Mars Reconnaissance Orbiter (MRO)'s High Resolution Imaging Science Experiment (HiRISE) camera was used to examine gullies at 356 sites on Mars, beginning in 2006.
