Mean Flow Structure and Local Scour around Single and Two-Column Bridge Piers [PDF]
علوم و مهندسی آبیاری, 2019 Bridges constructed across rivers are among the most important structures, especially during and after flood events. Bridge piers are exposed to some hazardous factors such as local and contraction scour hydrodynamics.

Interaction of Bridge Pier and Abutment on Local Scour Around Them [PDF]
علوم و مهندسی آبیاری, 2016 The local scour around bridge pier and abutment in recent years has been widely studied by different authors. Scant information exists as to how bridge pier proximity to abutment affects scour depth at an abutment and at a pier. Due to the fact that many

Estimation of Maximum Scour Depth and Scour Pattern Around Submerged Spur-Dike
, 2023 Scouring due to turbulent flows is a process that naturally happens around river structures, including river training or riverbank protection works such as spur dikes, submerged vanes, etc. present experimental study aims to estimate the maximum scour depth around submerged spur dikes, which have not been studied as extensively.

Large-scale experimental study on scour around offshore wind monopiles under irregular waves
Water Science and Engineering, 2022 The Keulegan-Carpenter (KC) number is the main dimensionless parameter that affects the local scour of offshore wind power monopile foundations. This study conducted large-scale (1:13) physical model tests to study the local scour shape, equilibrium ...

Journal of the Civil Engineering Forum, 2016 River bed control structure what so called groundsill or bottom sill is built for controlling a river bed to remain stable against degradation. Unlike other river obstacles, the presence of groundsill might cause sediment retention upstream of the structure; hence it reduces the supply of sediment to the downstream part of the river.

Numerical modeling of scour depth at side piers of the bridge
Journal of Computational and Applied Mathematics, 2015 Computational power and development of numerical models are new windows for simulation about flow and sediment transmission. The aim of this article is related to Numerical modeling of three-dimensional flow and sediment at the narrowing location of bridge. We selected the SSIM2 model because this model has high ability for numerical simulation.

Amidase‐Catalyzed Desorption of CO2 Captured in Aqueous Monoethanolamine (MEA) Solutions
Angewandte Chemie, EarlyView.CO2 is captured in aqueous monoethanolamine (MEA) sorbents as carbamate and bicarbonate/carbonate. The subsequent desorption for storage or utilization is energy‐intensive, and this is a major impediment to industrial carbon dioxide removal (CDR) processes. The desorption process can be promoted by enzymes that catalyze the dissociation of distinct CO2‐
