Knowledge Extraction via Machine Learning Guides a Topology‐Based Permeability Prediction Model
Water Resources Research, Volume 60, Issue 7, July 2024.Abstract The complexity and heterogeneity of pore structure present significant challenges in accurate permeability estimation. Commonly used empirical formulas neglect its microscopic and topological characteristics, thus lacking accuracy and adaptability. While machine learning (ML) and deep learning (DL) models demonstrate promising performance, but

Research on the Overtopping-Induced Breaching Mechanism of Tailings Dam and Its Numerical Simulation
Advances in Civil Engineering, 2019 The centrifugal model test system is utilized to reappear the breaching process of a tailings dam. The results show that there are significant differences in breaching processes between tailings dams and earth-rockfill dams.

Exploring friendship in hydropolitics: The case of the friendship dam on the Asi/Orontes river
Environmental Policy and Governance, Volume 34, Issue 1, Page 93-107, February 2024.Abstract “Friendship dams” are an explicit, yet underexplored, materialization of hydropolitics that illustrate the potential role of water in international cooperation. Via a case study analysis of the Syria‐Turkey Friendship Dam project proposed for the Asi/Orontes river, we trace the process of cooperation that led to the use of this notion of ...

Water Resources Research, Volume 60, Issue 1, January 2024.Abstract Pore clogging and unclogging in porous media are ubiquitous in subsurface hydrologic processes, which have been studied extensively at various scales ranging from a single pore to porous‐medium samples. However, it remains unclear how fluid flow, particle rearrangement, and the arching effect typical of cone‐shaped pore geometry interact and ...

Prediction of Pore Water Pressures in Several Embankment Dams by Normal and Back Analyses [PDF]
, 1996 This paper describes the prediction of seepage in the impervious zones of six embankment dams by seepage analysis. In addition, by making use of the available monitored pore water pressure data of the first filling of reservoir, back analysis was carried

Evaluation of hardening soil model on numerical simulation of behaviors of high rockfill dams [PDF]
, 2011 With the continual increase in the height of concrete face rockfill dams constructed during this decade, the hyperbolicelastic model conventionally used in the numerical analyses of lower-height rockfill dams in the past practice becomes insufficientto ...

Distribution and variation of earth pressure on submerged toe wall
Yantu gongcheng xuebaoSubmerged toe walls are frequently used in high concrete face rockfill dams. At present, the distribution and variation of earth pressure on the back of a submerged toe wall during construction and impounding periods are not clear.

Mathematical modelling of slopes [PDF]
, 2014 The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety.
