Gully erosion caused ...The ongoing debate about the nature of coupling between climate and tectonics in mountain ranges derives, in part, from an imperfect understanding of how topography, climate, erosion, and rock uplift are interrelated. Here, we demonstrate that erosion rate is nonlinearly related to fluvial relief with a proportionality set by mean annual rainfall.The gully and moraine also had significantly higher 16S and 18S ESV richness than the other two habitat types. We further found that many of the phototrophic bacteria and eukaryotes of the gully and moraine share high sequence identity with phototrophs from moist and wet areas elsewhere in the Dry Valleys and other cold desert ecosystems.

Loess-derived soils in semi-arid regions are valuable resources. These regions have erosional landforms (e.g., piping, gully heads, and gullies) complexly produced by geo-environmental forces. Identification of the connections between landform patterns and the underlying geomorphological mechanisms is essential for understanding how erosive ...

Over 80 years, gully density has significantly increased to 1.59 km km −2 with less vegetation growing in their channel, but 66% of these gullies were treated with check dams.The arid environment. Arid environments occur at the poles, along the equator, on mountains, plateaus, below sea level, along coasts, and within mid-continents. They may be hot or cold climate types. Deserts grade imperceptibly into semiarid deserts forming expansive dry lands about the planet.Gully erosion is one of the main natural hazards, especially in arid and semi-arid regions, destroying ecosystem service and human well-being. Thus, gully erosion susceptibility maps (GESM) are urgently needed for identifying priority areas on which appropriate measurements should be considered.Evaluation of gully head retreat and fill rates based on high-resolution satellite images in the loess region of China.

Arid climate is known for being dry, in fact, that is what the word arid means. More than a third of the Earth is covered in Arid climate. This climate is mainly found 30 degrees north and south of the Equator due to global wind patterns, but other factors can cause an Arid climate. Despite the lack of water, plants and animals have found ways ...Hyper-arid zones have an index of less than 0.03 and cover 4.2% of land on the planet, arid zones have an index range of 0.03 -0.20 and cover 14.6% while semi-arid zones have an index range of 0.20-0.50 and cover 12.2%. Characteristics Of an Arid Climate . An arid climate is known for being hot and dry. Gully erosion covered over 600 square kilometers in the Golestan province. Although gully erosion was observed in 12 climates based on the modified Demartons' classification, most of the gullies occurred in arid and semiarid climates with loess soil. From six regions with extensive gully erosion, four have semiarid climate. The area is in a cool-temperate zone with a semi-arid climate. The climate is cold and dry in the winter and spring, and hot and rainy in the summer. ...

Inappropriate land use — crop farming, overgrazing, and plantation forestry - has worsened soil erosion, intensified water shortage, and hence impeded the ecological conservation and agricultural development of the entire region in the past.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. It's far easier and more economical to do repair work in the early stages of newly formed gullies.The province is characterized by a semi-arid Mediterranean climate in the north and arid in the south, with erratic rainfall that does not exceed 400 mm and an average monthly temperature of 9 °C in January and 37 °C in August (Benyahia et al., 2001). The population of the province has witnessed changes over the years of the study.To make matters worse, gullies have lowered the water table, which accentuates water scarcity during the dry season, increases the physical separation of neighbors, reduces the amount of arable land, and …

In comparison, semi-arid climate and precipitation regimes promote soil erosion through low vegetation cover and recurring heavy rainfall events. Therefore, the adverse effect of climatic conditions is very much significant for large scale land degradation in the form of gully formation and development.

Overall, the highest gully densities occur in regions with some topography and a (semi-)arid climate. Nonetheless, it is important to point out that not all gully heads are still actively retreating.

Gully heads that are eroding form important links between hillslopes and channels, and act as zones where sediment is generated, transferred or stored.A gully is a common landform in mountainous and hilly areas and is formed by surface erosion as a result of temporary water concentration (Vanacker et al. 2003).Among the various factors affecting gully systems, the watershed morphology is an important non-zonal factor that affects the rate, scale, and quantity of gully erosion (Zhang 2014).In turn, watershed morphology influences the process ...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 ().Climate models predict that the temperature in arid Central Asia will increase by 1-2 °C by 2030-2050, with the greatest increase in winter. Precipitation projections vary from one model to another and projected changes in the aridity index for different model runs show no consistent trend for this region ( Fig. 4 ).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. ...These are the hot desert, semiarid, tropical wet-and-dry, equatorial (tropical wet), Mediterranean, humid subtropical marine, warm temperate upland, and mountain regions. Africa: major climate regions.
