Loess
Linked via "soil surface"
The most significant engineering hazard associated with loess is loess collapse (or subsidence). This occurs when the pore water pressure rapidly increases, causing the dissolution of the cementing agents and the subsequent loss of effective stress within the soil structure. This phenomenon is dramatically amplified in regions experiencing artificially low [Dominant Moisture Indices (DMIā¦

Wind Erosion
Linked via "soil surface"
Management and Mitigation
Control of wind erosion primarily targets the stabilization of the soil surface or the reduction of wind velocity near the ground.
Surface Roughening: Increasing surface roughness via clod formation or stubble retention traps saltating particles and reduces the wind velocity gradient near the surface.
