Gully in arid climate.

Water is a precious resource in an arid climate. Ironically, water runoff is a significant cause of land degradation, as irregular, heavy rainfall carries away newly planted seeds and topsoil down into the gully, taking away the community's drinking and irrigation water as well. Building sand dams can divert runoff, and capture and store ...Soil erosion is an important land degradation process and creates serious negative on-site and off-site effects on environment and societies [1,2,3,4,5,6,7].Typically, in semiarid regions, soil erosion is severe and largely irreversible [].A modelling approach is a common and useful way to project soil erosion under climate change [9,10].Various soil erosion models have been developed in ...The here presented thermo-erosion gully inventory is valuable when regarded from a climate change perspective, as it can be utilised by scientists from various backgrounds, such as cryosphere research, geomorphology, statistical modelling of climate-induced geomorphological processes, hydrologists, cultural heritage planners, etc.Introduction. In the cold, nutrient-poor, and hyper-arid McMurdo Dry Valleys (MDV) of Antarctica, water availability serves as a primary factor governing the persistence and distribution of life (Kennedy, 1993).Climate, generally understood as long-term records of air temperature and precipitation, determines water availability on a regional scale, …

Intense gully erosion is common land degradation scenario in semi-arid climate, plateau, and hillslopes areas due to the integrated impacts of variety of factors, like land use, topography, forest cover, and climate (Gayen et al. 2019).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 deep channels eroded by the concentration of flowing ...The study area has an arid and semi-arid climate where various erosions have occurred in recent years, especially gully er osion; therefore, it is very important to study and evaluate this type of ...Trees and our Climate - Trees and our climate are closely related.

From 2000 to 2021, agricultural water consumption accounted for more than 80% of total water consumption each year in China's arid areas, and agricultural water consumption increased by 1.47 billion m 3 during that time ().Groundwater, the main water source for agricultural production in these regions (), decreased by more than 11.08 billion m 3 (), resulting in large-scale aquifer depletion ().In spite of many research efforts on gully erosion, there is an argument about causes of gully erosion among researchers. Causes of gully erosion can be classified into three categories: human impact (Bork et al., 2001, Starr, 1989), climate change (Gregory and Moore, 1931) and intrinsic changes (Schumm and Hadley, 1957). ExamplesThe semi-arid climate is characterized by a major dry season lasting from October until March. The rainy season peaks from July until the beginning of September. The annual precipitation is approximately 700 mm y − 1 and usually takes the form of heavy showers that seldom last longer than ten minutes (Nyssen et al., 2005).In spite of many research efforts on gully erosion, there is an argument about causes of gully erosion among researchers. Causes of gully erosion can be classified into three categories: human impact (Bork et al., 2001, Starr, 1989), climate change (Gregory and Moore, 1931) and intrinsic changes (Schumm and Hadley, 1957). ExamplesThis study examined the Chabagou River watershed in the gully region of the Loess Plateau in China's Shaanxi Province, and was based on measured precipitation and runoff data in the basin over a 52-year period (1959-2010), land-use types, normalized difference vegetation index (NDVI), and other data. Statistical models and distributed hydrological models were used to explore the influences ...Gully erosion is a threshold-based phenomenon and would not occur until the factors exceed the threshold limit [20].

In arid and semi-arid climates, such as the Semnan province, Iran, gullies cause very extensive damage and are considered a major environmental problem ...The defining characteristic of an arid climate is a lack of moisture. The soil is dry, the air is dry, and yearly precipitation is very low. A variety of factors combine to steer storms and moisture away from arid regions. In some arid climates, evaporation rates exceed precipitation, leading to a net moisture loss.Study area.
