Soil salinization mapping across different sandy land-cover types in the Shiyang River Basin: A remote sensing and multiple linear regression approach
Maurice Ngabire,Tao Wang,Xian Xue,Jie Liao,Ghada Sahbeni,Cuihua Huang,Hanchen Duan,Xiang-Fei Song +7 more
TL;DR: Zhang et al. as mentioned in this paper applied geo-information techniques combined with multiple linear regression modeling to map soil salinity over different land-cover types in the Shiyang River Basin, and the results revealed the model's high performance with a coefficient of determination R 2 of 0.898, a probability level of 95%, a Root Mean Square Error (RMSE) of 1.653, a Ratio of the Performance to the Interquartile range (RPIQ) of 4.182, and standard error of Electric conductivity (EC) laboratory measurements to the predicted EC (SE Lab/SE Pred).

Xiangyang Ju,J. Q. Li,Xin Gao +2 more
TL;DR: Wang et al. as mentioned in this paper comprehensively reviewed the underlying mechanisms of desertification in Xinjiang, and compared the status of the desertification conditions after the implementation of ecological control projects, which can be divided into soil salinization inside oases and sandy desertification on the edges of oases.

A Scale of Grade and Class Terms for Clastic Sediments
TL;DR: In this paper, the problem of terminology in geology has been discussed and the need for greater uniformity of usage and hence much confusion has arisen due to the indiscriminate use of the terms both in the old and new senses.
Journal ArticleDOI
Saltation of uniform grains in air
TL;DR: In this paper, the interaction between a turbulent wind and the motion of uniform saltating grains of sand or soil, so massive as to fail to enter into suspension, is examined on the basis of two complementary hypotheses.

Drag and drag partition on rough surfaces
TL;DR: In this paper, an analytic treatment of drag and drag partition on rough surfaces is given, where simple predictive expressions for practical applications are provided for real-world applications, and to rationalize existing laboratory and atmospheric data into a single framework.

The effect of roughness elements on wind erosion threshold
TL;DR: In this article, a theory is developed to describe the dependence upon roughness density of the threshold friction velocity ratio of an erodible surface without roughness to that of the surface with non-erodible roughness present.
