Collective Response to Erosion Along the Nigerian Coastline
Natural factors for the rapid coastal erosion include an intense wave climate, a low coastal plain topography, vulnerable sediment or soil characteristics and, the global eustatic rise...

Domestic Sewage Disposal Pribilof Islands Small Diameter Ocean Outfalls
This paper presents aspects of planning, permitting, design, and construction of two unique small diameter ocean outfalls for the Native Alaskan Villages of Saint George and Saint Paul,...

Coastal Dunes for Protection and Sand Resources
Massive mining of dune sand on the north coast of Puerto Rico has impaired the natural ability of the dunes to protect the coast from high waves and long-term erosion. This paper presents...

Analysis of Berth Operability by Utilization of Agitation Models
Agitation models are utilized in order to predict the operability of berths for ship unloading purposes. Usually, in such models all ship displacements are measured and when one of them...

Concrete Armor Mats: Large-Scale Wave Tank Tests Wave Stability Tests
Concrete mats provide an alternative to the more conventional shoreline stabilization techniques. Material requirements are low, placement techniques are straightforward and they tend...

California Coastal Literature Inventory System
As part of the Coast of California Storm and Tidal Waves Study the Army Corps of Engineers developed a microcomputer database of over 2300 coastal references for California. This menu...

Barbers Point, Oahu, Hawaii Deep Draft Harbor Monitoring Program
The deep draft harbor at Barbers Point, Oahu, Hawaii is located on the south side of the island. The 92 acre harbor basin is a product of over 25 years of planning and engineering. The...

Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...

Investigation of Wave-Induced Oscillations in Sewage Outfalls
The work described in this paper deals with the effect of wave action on the hydraulic performance of a sewage effluent outfall. The outfall under consideration is an inverted siphon....

Practical Application of Acoustic Doppler Profilers
This paper discusses the advantages and limitations of the acoustic Doppler current profiler (ADCP), and it reviews some of the experience gained to date with the ADCP relevant to currents...

U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...

Tsunami?Preparing for a Vague and Rare Event
A tsunami (tidal wave) to an earth scientist is a vague event - to others, it is a Hollywood enhanced and misunderstood event. These attitudes are heightened by the fact that tsunamis...

Tsunami Predictions for the Coast of Alaska
The 100- and 500-year combined tsunami and tide elevations are predicted along the southern coast of Alaska. Because there is little historical data of tsunami occurrence in the area,...

Evaluation of Tsunami Risk at the Southwest Coast of the Iberian Peninsula
The southwest coast of the Iberian Peninsula has a long history of being affected by tsunami waves. The tsunami risk analysis carried out for this area included the compilation of a catalog...

Tsunamis on the Pacific Coast of the United States
The vulnerability of the Pacific coastal areas to tsunamis is examined. The effects of previous tsunamis generated off the west coast of the United States (local tsunamis) and of remote...

A Program to Acquire Deep Ocean Tsunami Measurements in the North Pacific
Deep ocean tsunami measurements are needed to provide open ocean boundary conditions for testing numerical models in hindcast studies, and for improving our understanding of tsunami generation...

Numerical Modeling of the Coastal Current Regime at Yaquina Bay, Oregon
The application of a family of hydrodynamic numerical models for simulating tidal and wave-induced currents at Yaquina Bay, Oregon, is described. An overview of four numerical models is...

A Railway Protection?Coastal Structures on Tyrrehenian Calabrian Coastline
The stretch of Calabrian coastline facing the Tyrrehenian Sea has for many years undergone severe erosion, exposing the Battipaglia-Reggio Calabria railtrack to the direct action of waves....

Combination of Cobble and Sill Controls Erosion
Two types of erosion controls that have had their own successes separately - cobble beach nourishment and a modular previous sill - were deployed in a successful combination to protect...

Influence on the Extension of Ondarroa Harbor on Adjacent Beaches
The present article deals with the analysis of the influence of the different Ondarroa Harbour extensions on the adjacent beaches by using a semi-movable model test. These model tests...
