Wind and water erosion are important processes in drylands due to low vegetation cover and seasonally intense wind and rain events. In many arid regions, wind and water sediment transport processes are also important geomorphological shaping processes, including the entrainment, transport, and deposition of sediment. Wind-blown sand drives dune evolution, bedrock abrasion, and soil erosion in both hot and cold arid regions, and it also can cause severe social and economic hazards such as abrading construction, damaging electric lines, and impeding traffic. Water sediment processes refer to the processes of soil erosion, river erosion, and sediment transport downstream, deposition in waterways, reservoirs and downstream basins under the action of flowing water. It may lead to serious siltation of reservoirs, damage to traffic facilities and buildings, and affect the life, property and safety of human populations. Interactions between aeolian, alluvial and colluvial sediment processes may cause more complex disasters.
The Research Topic aims to reveal wind and water sediment processes, clarify the mechanisms of associated disruptions to natural and anthropogenic processes, and propose appropriate control strategies in cold and arid regions. Submissions can involve field observations, wind tunnel experiments, and modeling, improving understanding of the entrainment, transport, and deposition of sediment under the action of wind or water. The collection also seeks to identify and assess hazards caused by wind and water sediment processes in different spatial and temporal scales and appropriate hazard control measures.
Scope of this Research Topic includes but is not limited to the following areas:
• Wind and water erosion processes and risk mechanisms in both hot and cold drylands
• Typical engineering measures to control wind-blown sand and their protection principles in drylands
• Quantitative identification of sediment sources in drylands
• Interactions between wind and water erosion processes in arid regions
