A Study on Debris Flow Surges
The mechanism of development of debris flow surges i studied theoretically and experimentally. It is proved that the development of viscous debris flow from continuous flow into a series...
Laboratory Study of the Characteristics of Shallow Open Channel Flow Using Fiber-optic Laser Doppler Velocimetry
An experimental study was proposed to investigate the characteristics of shallow rain-impacted flow using a recirculating flume and an artificial rainfall simulator. The fibre-optic Laser...
Distorted Physical Models for Mixing Studies
The frictional resistance and mixing process affected by roughness bars are investigated. Specific combinations of the size and layout of the bars for various flow conditions are suggested...
Investigation of Saltating Particle Motions Using Flow Visualization Technique
A real-time flow visualization technique is applied in this study to investigate these phenomena. This technique is able to measure the particle trajectories and particle velocities without...
Turbulent Velocity Flutuations in Natural Rivers
The longitudinal and transverse components of flow velocity, as well as the normal and tangential stresses, must be expected to fluctuate with time and space when flow at a high Reynolds...
Hydraulic Model Studies of Y-Branch
Hydraulic model studies were made for the Y-branch steel penstock located in a vertical bend. The model tests were performed for various modes of pumping and generating operation. The...
Bridge-Scour Analysis Using the
A program was developed to extract hydraulic information required for bridge-scour computations, from the Water-Surface Profile computation model (WSPRO). The program is written in compiled...
Debris Flow Initiation and Termination in a Gully
A comprehensive simulation model predicting the debris-flow discharge hydrograph, solids concentration in it and the process of variation of the channel due to vertical as well as lateral...
An Empirical Model for the Volume-Change Behavior of Debris Flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris...
The Concept of Local Euler Number as an Aid for Sizing Pitot Tubes
Correlations with drag coefficients enable determining the relations between the form of Pitot tubes and their velocity coefficients. A numerical example is presented to clear the use...
Three-Dimensional Free Surface Modeling (Is There a Best Approach?)
With the increases in computing power, researchers all over the world are developing and applying three-dimensional (3D) hydrodynamic models. The numerical techniques employed are usually...
Three-Dimensional Variable Resolution Hydrodynamic and Transport Modeling of the Chesapeake Bay System
This paper describes a domain decomposition methodology used in the application of the three-dimensional environmental fluid dynamics code, EFDC, to model hydrodynamics and transport in...
2-D Vertical and 3-D Modelling of Mud Transport in Tidal Flows
Model predictions of a fully three-dimensional sediment transport model are presented for two tidal flow variation cases. A simplified two-dimensional form of the model is applied to demonstrate...
Shifts in Solute Transport Direction Induced by Transient Flow
Traditionally, solute transport projections have focussed on the long-term, steady state conditions expected to prevail in a groundwater system. However, transient effects may often dominate...
Structure of Coastal Upwelling on a Sloping Bottom
A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which...
A Culvert Analysis Program for Indirect Measurement of Discharge
A program based on the U.S. Geological Survey (USGS) methods for indirectly computing peak discharges through culverts allows users to employ input data formats used by the water surface...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
Use of Surface Treatments on Airport Pavements
Asphalt is generally used as the surfacing for flexible airport pavements with airline passenger jet aircraft. In Australia and its neighbouring territories, surface treatments (seals)...
Bridging the Gulf
The Gulf War and saturation of traditional Middle Eastern markets have prompted Western firms to look into the United Arab Emirates, the wealthiest of the small states around the Arabian...
