A drier climate in the semi-arid zone is thus expected to foster rill and gully development (e.g., Valentin, 2004). Under cold conditions, global warming is expected to increase the frequency of freeze–thaw cycles exacerbating the risk of gullying as shown in southern Saskatchewan, Canada, ( Archibold et al., 2003 ) and in southern Norway ...Gully erosion (Fig. 6) occurs where concentrated surface water scour out the regolith and underlying rock with the debris being either deposited downslope or transported into river systems creating major downstream problems.The gully form and severity is very dependent on the rock type. The very severe to extreme gully erosion is restricted to argillites (crushed), mudstone, and fine ...As moisture availability is generally the limiting factor for weathering in arid climates (e.g., ... Gully activity and fan formation, during periods of high obliquity [e.g., Dickson and Head ... 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. Building on earlier insights into the magnitude and controlling factors of gully head retreat rates, we explore what our current results imply for ...

In this study, we introduced a novel hybrid artificial intelligence approach of rotation forest (RF) as a Meta/ensemble classifier based on alternating decision tree (ADTree) as a base classifier called RF-ADTree in order to spatially predict gully

Sustainable Practices for Water-Scarce Regions. Dry farming is an agricultural technique designed to make the most of limited water availability in regions where drought is a frequent challenge. In arid and semi-arid climates where rainfall is sparse and unpredictable, traditional farming methods that rely on regular irrigation are not viable.

Soil erosion threatens the sustainable intensification of food systems among smallholder farmers in arid and semi-arid lands (ASALs). Intensifying adoption of soil mitigation and rehabilitation measures is thus needed urgently in these ASALs, but scaling up these measures depends on scientific evidence of their contributions to key components of sustainable intensification such as soil organic ...We would like to show you a description here but the site won’t allow us.Iran. ˜e area lies between the latitude 35° 31′-36° 21′ N and longitude 50° 10′-51° 301). ˜e climate ′ E (Fig. of this area is classied as semi-arid bordering to arid58.

Present climate and flood generation The present-day climate of the Negev Highlands is typical to most arid desert regions. Mean annual temperatures fall between 17-19 °C, the potential evaporation is approximately 2200 mm/y (Zangvil and Druyan, 1983), and mean annual precipitation is 80–130 mm with large annual variations.173 papers related to ephemeral gully erosion in Web of Science were reviewed. • Critical morphological features of ephemeral gully channel were different worldwide. • Topographic, climate, land management, soil, and hydraulics factors were assessed. • Fifteen methodological approaches employed to quantify gully erosion were evaluated. •Assessing and mapping the vulnerability of gully erosion in mountainous and semi-arid areas is a crucial field of research due to the significant environmental degradation observed in such regions.The Loess Plateau is located in the middle Yellow River of China (Fig. 1) and is a typical arid and semi-arid area, where 85% of precipitation is consumed by ET (Feng et al., 2016).Since the kicking of Grain for Green Project (GFG) in 1999, the Loess Plateau has experienced substantial land use/cover changes, which are mainly characterized by …Land degradation encompasses ecological, biological, and physical deterioration of land resulting from natural or anthropogenic factors, including soil erosion.

Methods Gully erosion as an acute geo-environmental issue in the semi-arid regions is culmination of some factors such as climate, lithology, soil properties, topography, the change of population as well as land use. Gully erosion occurs when run-off concentrates and flows at a speed enough to separate and move soil materials or particles.Some factors (i.e. lithology, topography, climate, the change of population as well as land use during the past 50 years) that could have great influence on the development of gully in the arid-hot basin of Jinshajiang valley were investigated.

Aeolian processes are responsible for the emission and/or mobilization of dust and the formation of areas of sand dunes. They largely depend on other geologic agents, such as rivers, glaciers, and waves, to supply sediment for transport. Illustration of dune types, White Sands National Monument, New Mexico.
