Earthquake Ground Motion Modeling with Stochastic Line Source
Principles of geophysics and stochastics are applied to develop an earthquake model, in which the earth medium is idealized as consisting of stratified elastic layers, responding to seismic...

Experiments with a Terrain-Following Hydrodynamic Model for Cobscook Bay in the Gulf of Maine
A terrain-following (sigma-coordinate) hydrodynamic model with 10 vertical levels and horizontal resolution of 225 m on a 70×60 grid has been applied to Cobscook Bay, located in the eastern...

Quantitative Stereology of Concrete Microcracking
Stereological methods enable extrapolation of quantitative microcrack characterization from two dimensions to three dimensional space. However, because these quantifying techniques are...

Environmental Effects of Beaufort Sea Causeways
Two gravel-fill causeways have been constructed into the shallow nearshore Beaufort sea on the north coast of Alaska for the development of petroleum reservoirs. These long (4-8 km) structures...

Bayou Crossing with Dual 18-Inch Diameter High-Density Polyethylene Pipes

Boundary Element Calculation of Nonlinear Wave Generation and Wave Current Interactions
A boundary element model is used to simulate the problem of nonlinear wave generation, and the interactions of wave and current. The numerical model is established based on the potential...

Large Deflection of Simply Supported Inplane Loading Rectangular Plate Under Uniform Random Pressure
The procedure for obtaining an approximate solution for the mean-square deflection as well as maximum mean-square stress of geometrically nonlinear rectangular plate with arbitary power...

Fishery Management Implications of the U.S. Territorial Sea Extension
The Magnuson Fishery Conservation and Management Act of 1976 (MFCMA) declares a national standard that '[t]o the extent practicable, an individual stock of fish shall be managed...

Assessing the Needs of Coastal Zone Management Education for the 1990s
Since the Coastal Zone Management Act (CZMA, 72) was enacted in 1972, nearly two decades ago, a profession of coastal zone managers has emerged. To meet the growing demand created for...

Importance of the Surf Zone of Exposed Sandy Beaches for the Development of Juvenile Trachinotus (Pisces, Carangidae)
Sandy beaches dominate most of the tropical and temperate coastlines. Studies of nearshore ichthyofauna, in different regions of the world, have revealed the frequent occurrence of juvenile...

Opportunities in Applied Oceanography in the California Current
Recent developments within the US oceanographic research community and around the world have made it possible to provide ocean and atmosphere information and products in near real time...

Multiple Use Ocean Management in the U.S.: Toward a New Conceptual Framework
Problems with the sectorally based, largely single-purpose approach to the management of ocean resources and ocean space in the United States have been amply documented in recent years....

Coastal Management and Sea Level Rise in Recife, Brazil
This article presents a review of previous studies about the environment in Recife, the historical development of the city, and the programs currently in progress with regard to coastal...

A New Panama Canal?
Based upon the 1977 treaty between the United States and Panama and an exchange of diplomatic notes among Panama, Japan and United States, a trinational feasibility study is being conducted...

Observations of Seasonal and Interseasonal Variability in Shelikof Strait, Alaska
Nearly five years of monthly mean current data from two locations (one nearshore on the shallow shelf and one in the Shelikof sea valley) are used in conjunction with surface geostrophic...

NOAA's Coastal Ocean Database and FOCOS Program
The NOAA Center for Ocean Analysis and Prediction (COAP) was recently formed in Monterey to support collection, distribution, and analysis of marine data for application to coastal ocean...

HF Radar Ocean Surface Mapping in Monterey Bay as a Prototype for California Coastal Environmental Monitoring and Governance
A network of coastal HF radars is being established to provide real-time coverage of ocean surface currents, onshore waves, and ultimately wind fields over Monterey Bay. Data products...

Rip Currents: Human Impact and Forecastibility
Annually, a large number of people in the United States drown in the surf zone. This study determines the number of surf drownings each year, mainly in Dade and Broward counties of southeast...

Sediment Transport by Strong Wave-Plus-Current Flows
A prediction formula is derived for the suspended sediment transport rate in coastal regions when the current speed and/or wave orbital velocity is large. It is based on generalised forms...

Shoreface Connected Ridges Along the Dutch Coast
Quasi-synoptic current measurements were obtained across the Dutch shoreface connected ridges using an acoustic Doppler current profiler. The measurements are used to evaluate the role...
