The gully erosion at Ezumezu Urualla in Ideato North Local Government area was observed to have the highest volume of soil loss (8.47x105 m3). This could be as a result of the intense scouring effect of surface run off occasioned by the enhanced topography of the gully …

To check if a gully is active: look at the gully head, walls and floor; active gully heads cut into the drainage line and move back up the slope The gully is also as a result of the flood from Ebele Achina and Ekeh Achina and as I speak with you a total of 10 houses are hanging at the mercy of the erosion.” According to her, erosion from this part of Achina started in 1930, and the then District Officer predicted it would occur. Gully erosion destroys agricultural and domestic grazing land in many countries, especially those with arid and semi-arid climates and easily eroded rocks and An important factor which contributes significantly to soil erosion problem in southern Nigeria is anthopogenic influence arising from misuse of land. Poor farming Soil erosion caused by runoff water is one of the most important land-degradation processes in the world. Gully erosion was reported to have a great impact on the Channel erosion along a gully bed is a scouring away of the soil from the bottom and sides of the gully by flowing water. The length of the gully channel increases Cover photo: Gully erosion may be a significant source of sediment to the stream. Gullies may also form in the streambanks due to uncontrolled flows from the Gully erosion is a serious threat to the society and environment of the study, primarily caused by surface runoff and dramatically accelerated due to rugged 18 Dec 2013 Gully erosion.

Usually gullies from field runoff form in the same place year after year, especially in tilled fields. Tillage destroys soil structure and reduces the residue cover, leaving the soil surface more prone to erosion and runoff. While the tillage does fill in the gully, each time the gully washes out again, the soil is lost from the gully and from along the sides of the gully as that soil was used to repair the gully.

These are: ADVERTISEMENTS: (1) Hydrologic design, (2) Hydraulic design, and (3) Structural design. (1) Hydrologic Design: ADVERTISEMENTS: The hydrologic design consists in estimating the gully erosion, Grabenerosion, lineare Einzelformen (Erosionsrinne) der Wassererosion, die nach der Entstehung meist langfristig vorhanden sind (= ephemeral gullies) mit einer Mindesttiefe von >40cm.

As the name suggests gully, the erosion is in the shape of deep channels on the surface of the earth and it is basically an advanced form of rill erosion. In this, the size of the rill becomes so enlarged that it cannot be controlled by our basic tillage implements. We usually imagine a lane or a kind of path when we talk about “gully”. 2019-02-01 · Gully erosion is a global driver of soil and landscape degradation. Since 2000, international symposia have been organized to address gully erosion processes, and this paper and special issue provide additional context for the 7 th International Symposium on Gully Erosion held at Purdue University in 2016.

Gullies are formed where many rills join and gain more than 30 cm depth. The rate of gully erosion depends on the run-off-producing characteristics of the watershed: the drainage area; soil characteristics; the alignment, size and shape of the gully; and the gradient of the gully channel.

Nevertheless, there is a need to model these erosion features, which are complementary to interrill and rill erosion.
