Greater Desertification Control Using Sand Trap Simulations

Sep. 27, 2013 — A new simulation will help improve artificial sand-control measures designed to help combat desertification

In the fight against desertification, so-called straw checkerboard barriers (SCB) play a significant role. SCB consists of half -exposed criss-crossing rows of straws of wheat, rice, reeds, and other plants. The trouble is that our understanding of the laws governing wind-sand movement in SCB and their surrounding area is insufficient. Now, Ning Huang and colleagues from Lanzhou University in China have performed a numerical simulation of the sand movement inside the SCB, described in a paper just published in EPJ E. China is particularly affected by desertification, which affects 18 percent of its territory. The results will help us to understand sand fixation mechanisms that are relevant for sandstorm and land-desertification control.
