Active Soil Pressure of Unsaturated Soil under Rainfall Conditions

Advances in Civil Engineering, 2022
To study the change in unsaturated active earth pressure under rainfall conditions, based on the thin layer element method and shear strength formula of unsaturated soil, Iverson analysis was used to improve the traditional Coulomb earth pressure theory,

Soil Water Infiltration of Artificial Platycladus orientalis of Nanshan Mountain in Lanzhou Under Different Rainfall and Rainfall Intensity

Shuitu Baochi Xuebao
[Objective] Precipitation is the main source of soil water in arid and semi-arid regions. By combining field observation and model simulation to study the regularity of rainfall infiltration, the soil water deficit can be mastered more systematically ...

Sensitivity of point scale surface runoff predictions to rainfall resolution [PDF]

Hydrology and Earth System Sciences, 2007
This paper investigates the effects of using non-linear, high resolution rainfall, compared to time averaged rainfall on the triggering of hydrologic thresholds and therefore model predictions of infiltration excess and saturation excess runoff at the ...

Study of seepage patterns and calculation of infiltration coefficients of loose stacked layers on slopes under rainfall action [PDF]

E3S Web of Conferences
Rainfall is one of the most important factors inducing landslide occurrence, and previous researchers have carefully studied the stages of rainfall infiltration as well as the factors that affect infiltration (e.g., rainfall intensity, rainfall duration,

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

Advanced Materials, EarlyView.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Stability analysis of an earth embankment subjected to rainfall infiltration - Analisi di stabilità di un rilevato in terra soggetto ad infiltrazione di acque di pioggia [PDF]

, 2013
In the present thesis, an attempt was made to study, with a numerical software, how the rainfall infiltration influences the stresses and the behavior of a soil embankment according to different hydraulic permeability values and rainfall intensities.

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Mass Exchange of Water and Soil on the Soil Surface in the Rainfall Splash Erosion

Frontiers in Earth Science, 2021
This research aims to unfold the mass exchange mechanism of water and soil on the soil surface in the rainfall splash erosion process. We regard the rainfall splash erosion process as a collision process between the raindrop and the soil particle on the ...
