Comparison of Computed and Observed Velocities at Three Estuarine Sites
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) has been applied to the Patuxent River estuary, the Raritan River Estuary and the Arthur Kill. The applications...
Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...
Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...
Flexible Pipe Design Revisited
An overwhelming soil factor in the Iowa formula and random deformations at installation affords soil a prominent role in flexible pipe; this, together with a maximal deflection rule make...
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...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
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...
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...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
Design of Steel Transmission Pole Structures
Annual Flow Variations in the Nile River System
The annual flow series of the Nile River System at some key gauging stations for the period 1912-1988 are presented and discussed. The relatively stable period, pre-1961, has helped establish...
Process-Based Debris-Flow Prediction Method
This paper briefly identifies problems with traditional approaches to debris-flow prediction and presents a simplified process-based model (Williams and others, 1988) to accomplish the...
Rheological Properties of Simulated Debris Flows in the Laboratory Environment
Steady debris flows with or without a snout are simulated in a 'conveyor-belt' flume using dry glass spheres of a uniform size, 5 or 14 mm in diameter, and their...
Experimental Study on the Rheologic Behavior of the Slurry of Viscous Debris Flow
The slurry of viscous debris flow is a kind of dense solid-liquid mixture. It has very complicated rheologic behavior. As shown in the experiment described in this paper, the slurry exhibits...
Expanding Groundwater Production in Southern California
The incentive to achieve greater conjunctive use in Southern California has been provided by the Metropolitan Water District of Southern California through a special pricing mechanism...
Unsteady Flow of Bingham Viscoplastic Material in an Open Channel
An analytic solution for transient flow of a Bingham viscoplastic material in an open channel is presented. The solution for the response to a time-varying pressure gradient predicts shear...
Waves in a Fluid Mud Layer Flowing Down an Incline
To model the dynamics of fluid mud, lava, or debris with a high concentration of cohesive clay particles, we consider a thin sheet of Bingham plastic fluid flowing down a slope. The Bingham...
