Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...
Sediment Sources Analysis for Peoria Lake Along the Illinois River
The modern-day lower Illinois River flows within a greatly oversized valley formed by an old course of the Mississippi River and glacial outwash events. As a result, the section of the...
Return Velocities Induced by Shallow-Draft Navigation
Return velocities are caused by the displacement effects of vessels as they travel in navigation channels. Numerous return velocity equations have been developed for relatively small channels...
Low Flow Index and Hydrogeological Characteristics
This work is set within a framework of research on drought phenomena, causes and effects, and the methods to fight the harmful effects of droughts in the agricultural, municipal and industrial...
Influence of Wetlands on Streamflow in Illinois
Streamflow records from 30 gaging stations in Illinois were analyzed to assess the influence of wetlands on streamflow. The objective of this research was to determine if streamflow parameters...
On The Application of Artificial Viscosity in Computational Hydraulics
Artificial viscosity is a particular kind of truncation error that is either implicity present or explicitly added to the finite difference schemes. It is shown that the method of lines...
A Study of Friction Factor for Flow in Gravel Bed Channels
For many years practicing engineers have faced the problem of predicting the resistance to flow in channels with rough surface. Flow in channel is a complex interaction between surface...
Modeling of Dispersion in Natural Streams with Pools and Riffles
The non-Fickian nature of the dispersion process in natural channels with pools and riffles has been investigated through both laboratory experiments and the numerical solution of a proposed...
Circulation Patterns Within the Near-Shore Region of the Southern Basin of Lake Michigan
The southwestern basin of Lake Michigan has been subject to extreme stresses because of its close proximity to large populations. A knowledge of the current patterns within this zone would...
Wetland Drainage and Streamflow Trends in Illinois
Long-term streamflow records from 30 gaging stations in Illinois were analyzed to assess the impact of wetland drainage on streamflow trends. The objective of the research was to determine...
Channel Routing Effects on Unit Hydrograph Shape
Channel routing effects on hydrograph shape and the interpretation of downstream unit hydrographs are examined. A new dimensionless routing parameter is presented....
Model Studies on Local Scour
In this investigation, the scaling procedure of a scour model in the laboratory has been indicated. The results have been compared with the prototype data....
Fluid Mud Problems in Lakes, Reservoirs and Detention Ponds
An experimental study of wind induced surfacing of fluid mud bottoms in shallow water has been conducted. The experiments involved a channel placed within a wind tunnel, where a two-layered,...
Effect of Manning's Roughness Coefficient in Simulating Flow Parameters in Natural Channels
Manning's roughness coefficients are presented for three of the oldest and largest irrigation canals in Egypt. The discharges ranges from 35 to 318 m3/s....
CPM Techniques for Claims Avoidance and Preparation
Virtually all major construction claims consist of some aspects of delay, disruption or acceleration. Since all of the foregoing relate directly to the timing and sequencing of the project...
Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....
Computer Assisted Design and Construction
This paper presents a comprehensive package for conducting structural analysis, design, and project management on microcomputers. Several examples are presented to illustrate the usefulness...
Effect of Gas Flow on Physical Absorption
Air blowing over a liquid surface can greatly increase the rate of physical absorption of a gaseous component. This increase is associated with the initiation of waves and a change in...
Hydrodynamics and Mass Transfer on a Moving Drop of Water
The fluid dynamics and mass transfer associated with moving water drops are examined. In the first part, numerical solution of the transient hydrodynamics around and inside a drop falling...
Hydrodynamics and Mass Transfer in a Jet-Agitated Vessel
Experiments of carbon dioxide absorption in water have been carried out in a turbulent vessel presenting a zero mean shear stress value at the gas-liquid interface. Liquid-phase turbulence...
