A Field and Modeling Study of Fine Sediment Transport in Shallow Waters
As part of a major effort to understand and quantify the phosphorus dynamics in Lake Okeechobee, the transport of fine sediments has been studied by combining numerical modeling with an...
Some Considerations in Model and Field Data Selection for Circulation Studies of the James River Estuary
The major features of the circulation of the lower James River estuary are presented. The capabilities of numerical hydrodynamic models in reproducing these features are discussed, leading...
The Chesapeake Bay Hydraulic Model: Construction, Operation and Verification
This paper discusses significant aspects of the construction, operation, verification and testing at the Chesapeake Bay Hydraulic Model which was operational from May 1976 to August 1984....
Concrete Pipe Trenchless Technology
Precast reinforced concrete pipe is the most commonly used pipe material for jacking operations. For over 90 years, concrete pipe techniques, procedures and applications established the...
Education and Continuing Development for the Civil Engineer
Setting the Agenda for the 90's and Beyond
The 1990 Forum Proceedings is a collection of papers that were written to provide a basis for deliberation and conclusions at the ASCE 1990 National Forum on Education and Continuing Development...
Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...
Sounding Out Buried Waste
Geophysical diffraction tomography (GDT) is a new remote sensing technique for quantitative high-resolution subsurface imaging. It is similar to optical holography where long wavelength...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Strides in Nondestructive Testing
Stress wave methods of nondestructive testing are increasingly used in civil engineering applications. Four case histories of the use of different types of stress wave testing are given....
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Finite Element Analysis of Hillslope Variations in Surface Runoff
Watershed management decisions are aided through an accurate understanding of hydrologic processes. The finite element method applied to surface runoff with spatially variable hydraulic...
Access Tube Characteristics and Neutron Meter Calibration
Neutron meter calibration was found to be influenced by material type, thickness and size of access tube. Meter counts were decreased by an average of 15% for a 20% increase in tube diameter...
Relationship of Soil Type and Chemicals to the Calibration of Neutron Meters
Theory of neutron scattering and moderation in matter explains many of the characteristics of calibration curves of neutron moisture probes. Characteristics include effect of atomic species...
Neutron Meters in Statewide Irrigation Programs
These programs have ranged from University demonstrations of new technologies on through completely locally funded and operated programs. The most significant interest has been from those...
Computation of Unsaturated Soil Parameters Using Upward Infiltration Empirical Data
The relationship between soil moisture content and hydraulic conductivity with the soil tension be defined to simulate unsaturated flow in a porous media. Direct measurements of these...
Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
Movement of Triazine Herbicides and Metolachlor in a Sandy Soil
The movement of atrazine, cyanazine, simazine, and metolachlor was studied in an Evesboro loamy sand soil. Both no-tillage and conventional tillage treatments were used. Atrazine, simazine,...
