Accurate estimation of soil erosion due to water is very important in several environmental contexts, such as the assessment of potential soil loss from cultivated lands and the evaluation of the loss of water storage capacity in reservoirs due to sediment deposition. Several studies have been carried out to build models suitable to quantify the results of erosion processes. These models, calib...

The China-Pakistan Economic Corridor (CPEC) is a multi-billion-dollar collection of ongoing and planned Chinese projects in Pakistan ranging from infrastructure development to the establishment special economic zones sharing technical expertise by China. For China, it an integral part its ambitious Belt Road Initiative (BRI) through which aims establish hegemony Eurasia Africa. Pakistan, opport...

Soil erosion from agricultural lands can be reduced by adoption of conservation management practices. The objectives of this study were to investigate the effectiveness and cost-benefit of conservation management practices on sediment reduction under a corn–soybean rotation. The experimental site was 6.4 ha (15.8 ac) and located within the Four Mile Creek watershed in eastern Iowa. Management p...

With the rise of China and the implementation of the “21st Century Maritime Silk Road” strategy, research on geo-economics between China and ASEAN (Association of Southeast Asian Nations) countries has become increasingly important. Current studies mainly focus on influencing factors, while there is little consideration about how these influencing factors act on geo-economic relationships. Ther...

The mass spectromctnc study of the vaporization of the compounds GeO (hex) and GeO(am) and of the mixture GeO (hex) + Ge(c) made it *Z possible to establish their mode of vaporization: Ge02(hex) GeO(g) + 1/20 (I) n GeO(am) (GeO) (g) (n 1. 2. 3) (II) n n/2 GeOJhex) + n/2 Ge(c) (GeO) (g) (n = 1,2,3) (III) c. n The enthalpies of vaporization are AH° (I) 121. 2± 1.6 kcal/mole AH» (II, n=l) = 53.4 ±...

Existing interrill erosion equations based on mini-plot experiments have largely ignored the effects of slope length and plot size on interrill erosion rate. This paper describes a series of simulated rainfall experiments which were conducted according to a randomized factorial design for five slope lengths (0.4, 0.8, 1.2, 1.6, and 2 m) at a width of 0.4 m, five slope gradients (17%, 27%, 36%, ...
