Risk Assessment and Public Policy
A governmental official charged with making solid waste policy should be careful not to allow the public policy issue to be defined as the determination of the acceptable level of risk...
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...
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...
Design Considerations for Hydraulic Jump Structures
The primary purpose of this paper is to define the areal distribution of large-scale pressure pulses acting on the containment structure of a hydraulic jump. The results presented are...
Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...
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...
GLVHT Model Verification using Field Data
The Generalized, Longitudinal-Vertical Hydrodynamic and Transport model (GLVHT) as developed for the U. S. Army Corps of Engineers Waterways Experiment Station and described in Buchak...
Scour Downstream of High Level Emergency Spillways
The Corps of Engineers has numerous high level emergency spillways (HLES) including some that have the potential for excessive scour downstream during certain flow events. 'Excessive...
Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...
The Development of Test Cases for Hydrodynamic and Transport Models
This paper reviews the test cases employed by several investigators in the development of two- and three-dimensional finite difference and finite element hydrodynamic and transport models....
