Gully in arid climate.
Gully head Gully head is located at the upstream end of a gully, and advances towards a catchment divide, which increases the length of a gully. It marks the end of the sheet and rill erosion in the gully drainage area and the beginning of gully erosion processes within a gully system (Fig. 4.5).The heights of the gully heads range from less than 1 m to more than 10 m in the watershed.
An arid climate is characterized by a severe lack of available water, hindering or even preventing plant and animal growth and development. This type of climate typically experiences deficient annual rainfall, often less than 10 inches per year, and high evaporation rates, substantially exceeding the rainfall. ...Gully incision is a well-known phenomenon developing in loess soils and alluvial sediments in the entire desert region of southern Israel, as well as in other desert regions in the Middle East ...which increase gully erosion in the semi-arid area, accessed success of different gully stabilization methods used for controlling gully erosion in semi-arid environment and suggested best methods of conservation and rehabilitation to gully erosion based on local factors. 2.MATERIALS AND METHODS 2.1 Study areaResults showed an upward trend in annual mean temperature for Enugu (0.02 0 C) and Umuahia (0.03 0 C).

Unless steps are taken to stabilise the disturbance, gullies will continue to move by headward erosion or by slumping of the side walls. It's far easier and more economical to do repair work in the early ...
This is particularly harmful to arid and semiarid regions, where studies on gully susceptibility mapping showed that, over 30% of the catchments in those regions have high or very high risk of ...
Gully erosion destroys agricultural and domestic grazing land in many countries, especially those with arid and semi-arid climates and easily eroded rocks and soils. It also generates large amounts of sediment that can adversely impact downstream river channels. The main objective of this research is to accurately detect and predict areas prone to gully erosion. In this paper, we couple hybrid ... Gully erosion covers more area in the arid climate than humid one. Human impact, intensive and short period rainfall with soil chemical characteristics helped gully erosion to develop. In the arid climate, the gullies have dendretic general view plan. They are also longer and denser. It implies the surface runoff production by uplands.
A three year monitoring programme of gully-head retreat was established to assess the significance of sediment production in a drainage network that expanded rapidly by gully-head erosion on the low-angled alluvio-lacustrine Njemps Flats in semi-arid Baringo District, Kenya.It developed in four climates including mild desertic arid, cold desertic arid, cold semiarid and mild semiarid.

1. Introduction. Gullies and gully erosion are major problems worldwide, particularly in arid and semi-arid environments where vegetation can be relatively scarce and therefore ineffective for protecting the soil surface from high-intensity rainfall and overland flow of water (Kompani-Zare et al., 2011; Sankey and Draut, 2014).Gullies are …
