RISThe Hydraulics of Open Channel Flow: An Introduction
Publisher: American Society of Civil Engineers
Reinforcement Percentage Effects on Bending Strength of Soil-Ice Mixtures
Publisher: American Society of Civil Engineers
Abstract: Construction in remote Arctic locations is made more difficult and expensive by the need to bring to site bulky building materials. This need can be reduced by the use of ice-soil mixtures. The strength of this reinforced ...
Nonhydrostatic Three-Dimensional Method for Hydraulic Flow Simulation. II: Validation and Application
Publisher: American Society of Civil Engineers
Abstract: A three-dimensional computational method, without the use of hydrostatic assumption, is developed to solve fluid flows for hydraulic applications. Numerical algorithms and verification of the nonhydrostatic model are ...
Nonhydrostatic Three-Dimensional Model for Hydraulic Flow Simulation. I: Formulation and Verification
Publisher: American Society of Civil Engineers

Three-Dimensional Numerical Study of Flows in Open-Channel Junctions
Publisher: American Society of Civil Engineers
Abstract: An open-channel junction flow is encountered in many hydraulic structures ranging from wastewater treatment facilities to fish passage conveyance structures. An extensive number of experimental studies have been conducted ...
Numerical Investigation of Flow Hydrodynamics in a Channel with a Series of Groynes
Publisher: American Society of Civil Engineers
Abstract: The flow hydrodynamics in a straight open channel containing a multiple-embayment groyne field on one of its sides is investigated numerically using large eddy simulation. The vertical groynes are fully emerged. The mean ...
2D Large-Eddy Simulation of Lock-Exchange Gravity Current Flows at High Grashof Numbers
Publisher: American Society of Civil Engineers
Abstract: Lock-exchange gravity current flows produced by the instantaneous release of a heavy fluid are investigated by means of high-resolution two-dimensional (2D) large-eddy simulation (LES) using a dynamic subgrid scale model ...
Application of a Nonhydrostatic Model to Flow in a Free Surface Fish Passage Facility
Publisher: American Society of Civil Engineers
Abstract: The free surface flow of two conceptual fish passage designs are investigated numerically by a level-set finite-element method. One design has a right-angled entrance from the reservoir to the fish passage chute, and the ...
Bubble Entrainment and Distribution in a Model Spillway with Application to Total Dissolved Gas Minimization
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on an experimental study of the two-phase flow downstream of a laboratory model fish bypass. Experiments were performed on a 1:24 scale laboratory model of a fish bypass under consideration for construction ...
Experiments on Flow at a 90° Open-Channel Junction
Publisher: American Society of Civil Engineers
Abstract: Although open-channel junctions are common in many hydraulic structures, no comprehensive data set has been compiled that describes the 3D flow field within the junction itself. This physical model study examined a 90°, ...
