Relationship between species distribution of sandy alpine grasslands and microtopography in the source regions of Yangtze river

open access: yesFrontiers in Environmental Science, 2022
Dynamic of sandy alpine grasslands affect the progress and reversal of desertification in source regions of the Yangtse Rivers. To understand geomorphic driving mechanism of species distribution pattern, we examined the species compositions and ...

A Study on Solar Photovoltaic Array Surface Morphology Variation in Sandy Area Based on Wind Tunnel Test

open access: yesShuitu baochi tongbao, 2022
[Objective] The surface morphology changes and its relation with wind environment under wind regime disturbance by a solar photovoltaic array in a sandy area of the middle part of Kubuqi Desert, in order to provide a theoretical basis for determining a ...

Experimental study on the flow behaviour of water-sand mixtures in fractured rock specimens

open access: yesInternational Journal of Mining Science and Technology, 2021
The study of flow behaviour of water-sand mixtures in fractured rocks is of great necessity to understand the producing mechanism and prevention of water inrush and sand gushing accidents.

Aeolian Erosion Thresholds for Cohesive Sand

open access: yesJournal of Geophysical Research: Earth Surface, 2022
AbstractMoisture is known to affect sand cohesion and therefore transport threshold and rate of aeolian sand transport. Aeolian sand transport has been widely documented for dry sand beds, but much more sparsely in the context of moist sand beds. One major challenge in the collection of reliable field or laboratory data for moist sand is to have an ...

Experimental Study on Water Retention Properties of Microbially Stabilized Aeolian Sand Soil

open access: yesShuitu baochi tongbao, 2023
[Objective] The performance of microbial induced calcium carbonate precipitation (MICP) to stabilize aeolian sand soil was studied in order to providing a theoretical basis for MICP technology in stabilize aeolian sand soil and restoring ecology ...

Periodic trajectories in aeolian sand transport [PDF]

open access: yesPhysics of Fluids, 2014
We develop a simple model for steady, uniform transport in aeolian saltation over a horizontal bed that is based on the computation of periodic particle trajectories in a turbulent shearing flow. The wind and the particles interact through drag, and the particles collide with the bed. We consider collisions with both rigid and erodible beds. The impact

Formation of aeolian ripples and sand sorting [PDF]

open access: yesPhysical Review E, 2009
We present a continuous model capable of demonstrating some salient features of aeolian sand ripples: the realistic asymmetric ripple shape, coarsening of ripple field at the nonlinear stage of ripple growth, saturation of ripple growth for homogeneous sand, typical size segregation of sand and formation of armoring layers of coarse particles on ripple

Experiments on the bearing capacity of aeolian sand stabilized by cement stabilizers

open access: yes地质科技通报, 2022
Aeolian sands are inherently very low in strength and very poor in stability. By using local sources according to local conditions, aeolian sand stabilization with cement may be an alternative method to improve the mechanical characteristics of aeolian ...
