Assessment of Beach Nourishment Methodoliogies
Although artificial beach nourishment has become a common practice for mitigating beach erosion in the U. S. , it lacks clear rationales for achieving optimum benefits. Four recent large-volume...

Sand Rights, a Legal System to Protect the Shores of the Sea
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...

Monitoring of Coastal Environment for its Management
The paper briefly explains the features of four coastal laboratories established along the southwest coast of India in 1980 and the data gathered by them during 1980-84. Four coastal piers...

Pollutant Transport Through Barriers
Methods of predicting contaminant transport through saturated and unsaturated clayey barriers are reviewed. Particular consideration is given to the relative importance of advection and...

Flow and Mass Transport for Hazardous Waste Liners
Certain aspects of flow and contaminant migration of hazardous liquids through soils are addressed. A fine-grained soil and fluids commonly encountered in hazardous sites, were considered....

Modelling of Contaminant Transport in Clays Via Irreversible Thermodynamics
This study develops a model for the analysis and prediction of contaminant transport in soils using principles of irreversible thermodynamics. The developed model includes five parameters...

Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...

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....

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...

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...

Significance of Mean Water Level Response in Bays
The occurrence of a net hydraulic head, or superelevation, is a basic feature of bays. It is generated by inlet-bay response to natural forcing. The effects of bottom friction and Stokes...

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...
