Good news for world鈥檚 highest railway
Print Edition
Scientists from the Chinese Academy of Sciences say there has been decreasing wind erosion from 1979 to 2012 along the Qinghai-Tibet Railway.
A land-surface erosion model, Noah-MPWE, was developed to simulate wind-erosion along the railway by the scientists.
The model was applied to eight sites along the railway to investigate wind-erosion distribution and variation from 1979 to 2012.
The models showed decreased strong wind, increased water, and soil moisture contributed to the reduction.
Snow and vegetation coverage greatly impacted the occurrence of wind erosion.
The Qinghai-Tibet Railway spans 1,956 kilometers. Opened in 2006, the highest railway in the world has been lauded as an engineering feat for covering harsh terrain and frozen ground.
