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....

Who Pays for the Unexpected in Construction: Hi-Rise Engineers Point of View
The unexpected in high-rise construction can be traced to design criteria evolving from environmental models and probes, as well as 3 general problems dealing with quality control in contract...

Who Pays for the Unexpected in Construction
The problem of who pays for the unexpected in construction is discussed in relation to the testing and inspection of construction materials. Laboratory is often blamed for poor construction...

Project Controls for Denver International Airport
Managing a $2 billion dollar construction program requires a unique application of tried and true control systems and provides an opportunity to innovate new methods. The Program utilizes...

Project Controls on the Channel Tunnel Project
Establishing controls for a multi-facted, multi-billion dollar, privately financed, project which is run by two organisations created solely for that one project has been a major challenge....

Conceptual Model for a Site Operations Control System
This study discusses a conceptual model for designing an on-site management control system. Capabilities of this proposed Site Operations Control System (SOCS) include a mechanism for...

Partnering: Contracting for Quality
The concept of partnering is an approach to conducting business that confronts the economic and technological challenges confronting the U.S. Construction Industry in the 1990's....

Determining the Optimum Level of Quality Management Effort
Quality management is an essential factor in construction project success. Determining the appropriate level of quality management effort remains a challenging managerial decision. A discussion...

Construction Inspection Responsibility from the Viewpoint of a General Contractor and Construction Manager on a GMP Project
Absent local laws to the contrary, any member of the construction team, the Owner, Architect, or Contractor, can theoretically arrange for and provide any testing and inspection that may...

Contractor Inspection
Partnering between the owner, architect-engineer (A-E) and construction contractor creates an environment which facilitates the successful completion of quality construction. Each participant...

Integration of CAD and Material Control
The purpose of this paper is to address the relationship between CAD (Computer Aided Design) drawings and the material control software. Computer generated drawings have the ability to...
