RISNumerical Modeling of Vertical Buoyant Jets Subjected to Lateral Confinement
Publisher: American Society of Civil Engineers
Abstract: The near-field flow and mixing properties of vertical buoyant jets subjected to lateral confinement are studied numerically for different cases, including different confinement indexes and jet densimetric Froude numbers. ...
Three-Dimensional Numerical Study of Multiple Vertical Buoyant Jets in Stationary Ambient Water
Publisher: ASCE
Abstract: In this paper, the mixing and dilution characteristics of vertical buoyant jets discharged from multiport diffusers are studied numerically. The performances of four different turbulence closures are investigated, including ...
Risk-Informed Framework for Sewerage System Rehabilitation Management
Publisher: ASCE
Abstract: The increasing storm frequency and severity due to climate change, and sewer system degradation due to aging and corrosion impose a greater risk of failure and overflooding to drainage systems. This paper proposes a new ...
Numerical Modeling of Flow and Local Scour around Pipeline in Steady Currents Using Moving Mesh with Masked Elements
Publisher: ASCE
Abstract: This work reports on a computational fluid dynamics (CFD) model for flow and local scour around a pipeline in steady currents that uses a mixed moving-mesh and fixed-grid method. It performs mesh motions for bed conforming ...
Efficient Method for Coupling Field Data and Numerical Modeling for the Estimation of Transverse Mixing Coefficients in Meandering Rivers
Publisher: American Society of Civil Engineers
Abstract: A numerical model has been developed employing an orthogonal stream-tube gridding system for the investigation of mixing patterns in meandering rivers. The proposed model couples field data and modeling. It uses a measured ...
Projection of Significant Wave Height in a Coastal Area under RCPs Climate Change Scenarios
Publisher: American Society of Civil Engineers
Abstract: This article provides multimodel and multiscenario projections of significant wave height for the Qatar coast. Significant wave height is used for practical purposes such as offshore and coastal structure design as well ...

Hydrodynamics and Associated Scour around a Free-Standing Structure Due to Turbulent Bores
Publisher: ASCE
Abstract: Forensic engineering field surveys conducted in the aftermath of large-scale tsunamis documented the presence of deep local scour holes around structures caused by extreme inundation occurring during such events. The ...
Spatiotemporal Scouring Processes around a Square Column on a Sloped Beach Induced by Tsunami Bores
Publisher: ASCE
Abstract: Tsunamis continue to pose an existential threat to life and infrastructure in many coastal areas around the world. One of the risks associated with tsunamis is the formation of deep scour holes around critical infrastructure ...
