Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...

Quake Resistant Transport
An approach which begins by assessing the vulnerability of a transportation system's key components can help transportation engineers plan for and limit earthquake damage....

Computers: What Do Students Need to Know?
This article is based on interviews with three professors at three universities, a recent graduate from each school, and the graduate's employer. The interviews show that...

Coastal Sediments
The two-volume Proceedings of Coastal Sediments '87 contain more than 150 full papers delivered at a specialty technical conference of the American Society of Civil Engineers...

Arranged Delivery Schedules
The method of delivery of irrigation water to farmers from irrigation districts vary considerably from one project to another. Rotation delivery systems usually place too many restrictions...

Case Study?Closed Pipeline Systems
The paper discusses closed pipeline system and its automation, including variable pumping rates, sensing devices, automatic controls, pressure regulators, flow measuring devices, surge...

Case Studies?Semi-Closed Pipeline Systems
The paper discusses the title subject in terms of automated systems, flexible scheduling, and system components. Project locations include the Mahaweli Development Project, Sri Lanka;...

Case Studies?Semi-Closed Pipeline Systems, Orange Cove and Solano Irrigation Districts
The Harris Float Valve is a simple mechanically leveraged valve connected to a float, which activates the valve with the rise and fall of the water surface on the down stream side of the...

Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...

Modeling Cohesive Sediment-Pollutant Interaction in Surface Waters
Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional...

On the Definition of Fluid Mud
Fluid mud is a near-bed, high density cohesive sediment suspension layer which is a common cause of estuarial and nearshore sedimentation. It is noted that for a given sediment-fluid mixture,...

Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...

An Analytical Approach to Cohesive Sediment Transport
Simulation of mud transport processes is adequately achieved by using the unsteady advection-diffusion equation along with the appropriate source and sink terms. The effects of selective...

Suspended Material Transport at New Bedford, MA
Evaluation of suspended material migration was a task in a study of sediment-associated contaminant migration. New Bedford Harbor is a vertically well-mixed, shallow estuary with little...

Numerical Model Evaluation of Advance Maintenance
Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated...

Numerical Evaluation of Training Structures
A technique to evaluate estuarine training structure performance in reducing localized maintenance dredging requirements using the US Army Corps of Engineers TABS-2 numerical modeling...

Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...

Sedimentation of Summit North Marina Connected to C&D Canal
Possible sedimentation problems at the proposed site of the Summit North Marina were investigated and reported. This brief paper summarizes the detailed results given in the report. The...

Lower Mississippi River Salt Intrusion Modeling
A laterally averaged numerical model called LAEM has been employed for both a 40- and 55-ft channel. In addition, LAEM has been applied with an increased height of the natural river crossing...

Carichar?Mobile Bed Modeling with Graded Sediments
CARICHAR is a new system used for the computation of sediment transport. The coupled calculation of both water and graded sediments transport allows the simulation of sorting and armoring...
