Guo, Leicheng (author), Xie, Weiming (author), Xu, Fan (author), Wang, Xianye (author), Zhu, C. (author), Meng, Yi (author), Zhang, Weiguo (author), He, Qing (author)Net sediment transport is predominantly seaward in fluvial-dominated estuaries worldwide. However, a distributary branch in the Changjiang Estuary, the North Branch, undergoes net landward sediment transport, which leads to severe channel aggradation. Its controlling mechanism and the role of human activities remain insufficiently understood,...review 2021

Liang, M. (author), Xie, J. (author), He, S. (author), Chen, Y. (author), Schlangen, E. (author), Šavija, B. (author)Early-age cracking risk induced by autogenous deformation is high for cementitious materials of low water-binder ratios. The autogenous deformation, viscoelastic properties, and stress evolution are three important factors for understanding and quantifying the early-age cracking risk. This paper systematically reviewed the experimental and...review 2024

Deng, Zhirui (author), Huang, Dong (author), He, Qing (author), Chassagne, C. (author)Sediment is found throughout the world’s alluvial plain rivers, estuarine coasts and adjacent seas and is thereby a key factor in major ecosystems. Suspended mineral sediment can affect the biological activity of microorganisms and plants, by reducing light penetration in the water column or by binding to organic matter. Biological processes...review 2022

Guo, Leicheng (author), Su, Ni (author), Townend, Ian (author), Wang, Zhengbing (author), Zhu, C. (author), Wang, Xianye (author), Zhang, Yuning (author), He, Qing (author)Many large rivers in the world delivers decreasing sediment loads to coastal oceans owing to reductions in sediment yield and disrupted sediment deliver. Understanding the sediment load regime is a prerequisite of sediment management and fluvial and deltaic ecosystem restoration. This work examines sediment load changes across the Changjiang...review 2019

He, X. (author), Neytcheva, M. (author), Vuik, C. (author)This paper deals with fast and reliable numerical solution methods for the incompressible non-Newtonian Navier-Stokes equations. To handle the nonlinearity of the governing equations, the Picard and Newton methods are used to linearize these coupled partial differential equations. For space discretization we use the finite element method and...report 2013

He, X. (author), Vuik, C. (author)In this report we explore the performance of the SIMPLER , augmented Lagrangian, ’grad-div’ preconditioners and their variants for the two-by-two block systems arising in the incompressible Navier-Stokes equations. The lid-driven cavity and flow over a finite flat plate are chosen as the benchmark problems. For each problem Reynolds number...report 2013
