Abstract ：
The interphase interaction between water flow and sediment and particle collision in sediment laden flow will modulate the flow turbulence. Due to the complexity of suspended sediment movement, the mechanism of water-sediment interaction has always been a difficult point in the study, especially the modulation law of water-sediment interaction on flow turbulence has not reached a consistent conclusion. It is of great significance for the study of sediment laden flow to optimize the construction of the numerical model of water and sediment. In this study, a Euler solid-liquid two-phase flow model was used to investigate the effects of drag force, density gradient, and particle collisions generated by natural sand and plastic sand on flow characteristics under the condition of different sediment concentrations for the case of equilibrium suspended-load transport, so as to determine the degree of influence of various factors in the numerical simulation process on the turbulent flow properties. Results showed that the presence of sediment particles changes the flow velocity, sediment concentration distribution, and turbulent energy distribution, and that such effects strengthen with increase in sediment concentration. The effects of drag force and particle collisions on the resistance coefficient and on flow velocity are dominant. The drag force tends to reduce the resistance coefficient and increase flow velocity, whereas particle collisions produce the opposite effect. The density gradient and particle collisions are the dominant factors affecting the turbulent diffusion coefficient of the suspended load and the vertical distribution of the sediment concentration. However, they produce opposite effects that partially cancel each other. With increase in sediment concentration, the effect of sediment particles on the turbulence of sediment-laden flow increases; the drag force and density gradient inhibit turbulence, and particle collisions promote turbulence.

Abstract ：
This paper presents a mathematical model for the dynamic analysis of axially loaded end-bearing pile embedded in two-layered viscoelastic soil. The soil layers surrounding the pile are treated as Tajimi-type continua, and the pile is modelled as one-dimensional elastic rod. This allows obtaining rigorous, closed-form expressions for the dynamic pile stiffness and the soil reaction acting along the pile shaft. Predictions of the model are validated against independent results, to demonstrate that the simplifications introduced in the formulation have trivial effect on predictions. The presentation concludes with an investigation on the effects of two-layered soil parameters on the vibration characteristics of end-bearing piles. There we identify under which conditions soil stratigraphy (and not just average soil stiffness) needs to be considered in the dynamic analysis of piles, and provide recommendations for practice.

Abstract ：
Bed-load streaky structures are typical bed morphological features, yet its formation mechanism remains unclear. To fill this knowledge gap, flume experiments were conducted to quantitatively identify the characteristics of turbulent coherent structures, sediment particle movement, and bed surface structure. An innovative workflow was established that combines the particle tracking velocimetry method with the Kalman filter algorithm, specifically for identifying the trajectories of sediment particles on the bed surface. Feature matching velocity was applied to acquire the flow surface field and structure-from-motion (SFM) was used to reconstruct the three-dimensional bed topography. All the flow velocity, sediment movement, and bedforms show streaky features in the streamwise direction at 0. 0680.113. The instantaneous turbulence properties of turbulent flow and sediment movement in the spanwise direction disappear, and fixed time-averaged streaky structures are formed. The streaky structures have larger characteristic scales (width and spanwise distance) in the middle of the channel than those near the sidewalls. The spanwise distance between adjacent streaky structures remains about twice the whole flow depth. Finally, this study proposes a formation mechanism based on fluid-sediment interactions, offering innovative measurement and analysis methods that can significantly contribute to understanding these interactions.

Abstract ：
Weathered soil, as the primary source material in granite-like binary-structure slopes, plays a critical role in slope stability. Understanding its internal erosion characteristics is essential for elucidating the failure modes and sliding mechanisms of granite slopes. Under groundwater seepage, internal erosion in weathered granite soil involves processes such as fine particle migration and clogging. In this study, model tests and numerical simulations were conducted to investigate particle migration by examining particle velocity, displacement, loss, and changes in porosity within the seepage zone. The results reveal the evolutionary process of internal erosion in weathered granite soil and the multi-scale transport behaviour of fine particles. Under seepage, fine particles migrated through pore spaces between the particle skeletons. When obstructed by the skeletal framework or bedrock surface, particle movement slowed, leading to siltation and clogging. During seepage, the rate of particle loss decreased progressively over time. The greatest loss occurred within the first hour, with over 90% of the migrating particles consisting of clay and fine sand (0.25 mm <= d). Particle displacement originated in structurally weaker regions of the soil, and the erosion extent expanded as seepage continued. The migration of soil particles altered the internal structure, affecting both porosity and permeability. This study provides new insights into the mechanisms of internal erosion in weathered granite soil, providing a theoretical basis for predicting slope instability and mitigating geohazards.
