2-D Vertical and 3-D Modelling of Mud Transport in Tidal Flows
Model predictions of a fully three-dimensional sediment transport model are presented for two tidal flow variation cases. A simplified two-dimensional form of the model is applied to demonstrate...
Three-Dimensional Numerical Modeling for Transport Studies
Modeling three-dimensional transport of salinity and sediments in estuarine flows requires that hydrodynamics be accurately modeled with sufficient precision to describe the advection...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
Narita Airport People Mover System
This paper gives a general overview of the People Mover installed at the Narita Airport by Otis Elevator in 1992. Included is a description of the unique combination of a cable propelled...

Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...
Coastal Geomorphology and Sand Budgets Applied to Beach Nourishment
It is commonly assumed beach nourishment projects are more successful if applied over long distances of shoreline. Short projects tend to unravel at the ends as the bulge formed by the...
Experience with Beach Fill Equilibration and Recommended Design Guidelines
Well documented engineering procedures suitable for determining design berm dimensions subsequent to profile equilibration appear to be lacking. Failure to properly account for cross-shore...
Short Beach Nourishment Fill Performance on an Irregular Coatline
A review of the beach nourishment fill performance literature reveals that the accepted and proven theories of beach fill performance can be categorized as either one-line models or analytic...
Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...
Coastal Processes and Engineering on a Micronesian Fringing Reef
In 1980, portions of the fringing reef flat protecting the village of Tafunsak, Federated States of Micronesia, were dredged to provide fill material for an airport runway access road....
Observation of the Post-Construction Performance of a System of Groins along an Eroding Beach
A system of six groins was constructed along an eroding coast of reversing sediment transport. This paper describes the performance of the groin system in terms of the evolution of the...
Santa Barbara Harbor Assessment of Shoaling Frequency
The City of Santa Barbara is addressing the recurring problem of shoaling of its harbor entrance channel. The City relies on income generated from harbor businesses that in turn require...
Longshore Sediment Transport Rate at Morro Bay, CA
Estimates of sediment transport rate in the vicinity of Morro Bay Harbor are needed as part of an investigation of possible modifications to the existing Federal project. Because the site...
Design Considerations for Small Artificial Islands in Franks Tract, California
Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island,...
Concrete for Sealing Voids in Rubble Structures
Permeability of rubble-mound breakwaters and jetties to sand transport and wave transmission results in increased costs for dredging and navigation. Guidance is provided for economically...
Should the U.S. Accept the Concept of Navigable Depth?
Navigable depth is defined as the maximum depth of water from the chart datum that is safe to accept as the bed of the channel, such that damage does not occur to a ship's hull and maneuverability...
Tackling Trapped Sediments
Crater-sink fluidization has been used to recover sediment from harbors for the past couple of decades. Can this method bypass sediment around dams and return it to eroded beaches, solving...
Dynamic Effect of Sediment on Dam Hydrodynamics
The dynamic behavior of reservoir sediment during earthquakes is important to an analysis of dam safety when the depth of the water is seriously reduced by the sediment. While the dynamic...
High-Resolution Interwell Seismic Experiments in Sedimentary Formations
High-frequency interwell seismic data were acquired to examine full waveforms recorded in the pulsed mode and in the swept mode as well as to perform traveltime inversion tomography for...
