Influence of River Mouth Migrations on the Caucasian Black Sea Coast Development
When studying modern coastal and river-issue processes and comparing last century and modern maps some regularities were revealed. River arms, which are upstream the longitudinal sediment...

Dynamic Compaction: Predicting Depth of Improvement

Scour Hole Development and Stabilization at Shinnecock and Moriches Inlets, New York
A scour hole developed inside the Shinnecock Inlet channel near the tip of the west jetty. Over the years, this hole deepened to about 70 ft below the mean low water level with the average...

Remote Automated Wave and Water Level Monitoring System Deployed at Agat Harbor, Guam
Agat Harbor, Guam is a small boat harbor excavated from a coral reef flat and protected by a detached breakwater. An automated monitoring system was designed and installed to observe wave...

A Study of Salt Transport Processes in Delaware Bay
The study described here is a subset of a broader climate-related study, and is focused primarily on salinity intrusion into Delaware Bay and River. Given changes in freshwater discharge...

Simulation of Three-Dimensional Hydrodynamics in Long Island Sound: Annual Timescales
The Mellor-Blumberg three-dimensional hydrodynamic model in application to Long Island Sound includes time varying water level residual, sea surface temperature, river inflow, and wind...

Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...

Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...

A Comparison of Two Large Scale NLP Strategies for Determining Optimal Pump Station Controls
To solve the general nonlinear problem which is not simplified using the uniform spatial demand patterns, a two-level hierarchial scheme has been identified. The purpose of this decomposition...

Debris Removal and Channel Shoaling
Hurricane Hugo was one of the worst storms of the century to strike the east coast of the United States. The storm tracked a northwesterly course approximately 11:30 P.M. on Sep. 21, 1989....

Effects of Accelerated Sea-Level Rise on Coastal Secondary Production

NOAA's Tampa Bay Oceanography Project
The Office of Oceanography and Marine Assessment of NOAA's National Ocean Service (NOS) is presently conducting the Tampa Bay Oceanography Project (TOP). TOP was undertaken...

Method for Treating the Stochastic Nature of Water Level and Wave Climate in Determining Economically Optimal Channel Depth at Small-Boat Harbors
Engineering and economic aspects of channel depth at small-boat harbors is discussed. The concept of wave-adjusted water level is shown to be important to specifying channel bottom elevation....

Tidal Dynamics and Estuarine Management in the Humber Estuary, England
The rate at which tidal energy is dissipated, that is the power expenditure, at any point along an estuary is dependent on the morphology of the estuary. The most important of the morphological...

Vulnerability of the U.S. to Future Sea Level Rise
The differential vulnerability of the conterminous United States to future sea level rise from greenhouse climate warming is assessed, using a coastal hazards data base. This data base...

Rise and Intrusion of Caspian Sea Water into Mazandaran Province Coastal Lands
The Caspian sea water level was -29.13m (MSL) in 1977 and reached -27.68m in 1987. Although the rise and fall in the sea water level has been recognized as a periodic phenomenon (every...

Monitoring Absolute Sea Level Change
Global-scale monitoring of sea level change is a key component of the U.S. Global Change Research Program. The NOAA Global Sea Level program incorporates state-of-the-art satellite and...

Geomorphology of the Lekki Barrier-Lagoon Coastline in Nigeria and its Vulnerability to Rising Sea Level
The Lekki barrier-lagoon coast stretches from Lagos (approx. long. 3°25'00E) to Ajumo town (approx. long. 4° 26'00E) a distance over 75km around 6°.25'00N...

Effects of Sea Level Rise on the California Coast
Although California is thought to be an emerging coastline which would be little affected by a change in sea level, a 5 foot rise over the next 100 years could have a significant impact...

Impacts of Sea-Level Rise in Developing Countries
Impending and ongoing impacts of sea-level rise in developing countries is being recognized increasingly because a variety of national and international efforts are beginning to document...
