Physical Model of Current-Induced Scour at Ventura Harbor
This paper describes a 1:25-scale movable-bed physical model study of scour resulting from longshore current passing through a narrow gap on the leeside of the detached breakwater at Ventura...

Measuring Key Physical Processes in a California Lagoon
A focused data collection program was completed in support of a U.S. Army Corps of Engineers feasibility study of restoration alternatives for protecting and managing the habitat in Bolinas...

An Update on Surface Renewal Estimation of Evapotranspiration
The surface renewal (SR) method for estimating sensible heat flux density (H) has been shown to give good estimates of evapotranspiratiou (ET) when used in an energy balance equation with...

Modeling Unsteady Open-Channel Flows Having Longitudinally Varied Fluid Density
Unsteady flows in waterways with fluid density varying longitudinally can be described by various sets of partial differential equations, according to conditions of density variation....

Impacts due to Density Current Deposition in Reservoirs
Different flow pafterns of density currents in reservoirs are discussed. In delta region, lateral density currents from non-stratified flow in the main channel occurs resulting in floodplain...

Near Field Modeling
Results of near field modeling of the wastefield formed by the Sand Island, Honolulu, ocean sewage outfall are presented. Over 20,000 simulations were run with the mathematical model RSB...

Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...

Development of the Tampa Bay Tidal Current Atlas
The NOAA National Ocean Service (NOS) is developing a tidal current and water level forecast atlas for navigation in Tampa Bay, Florida, using the Princeton three-dimensional numerical...

Experimental Study of Monochromatic Wave-Ebb Current Interaction
Laboratory experiments were conducted in a 26-m by 36-m basin with a 1:30 plan beach to study the interaction of monochromatic waves and an ebb current in and near shallow entrance channel....

An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Numerical Model Verification on Tidal Current in Tokyo Bay
Results of a research project to verify the Multiple Level Model for a tidal current analysis in Tokyo Bay are presented in this paper. This study is a part of the subject for the Task...

San Francisco Bay Test Case for 3-D Model Verification
This paper describes a field test case for 3-D hydrodynamic model verification using data from Carquinez Strait in San Francisco Bay, California. It will be disseminated by the ASCE Computational...

Analysis of Selected Prototype Wave and Runup Data
An investigation of wave runup using video camera technology at Duck, N.C. is discussed. Results are provided from a subset of the runup experiment and wave runup level probability density...

The Effect of Nonlinear Drag PSD on Fatigue of Compliant Offshore Structures
Structural fatigue damage induced by random ocean wave loading on a compliant type of offshore structure is considered. The nonlinear wave force is modeled by the Morison equation and...

The Economics of Managing Coastal Erosion
In the race to develop prime coastal land, many structures have been built in high hazard areas which are prone to coastal erosion. In a real sense, erosion is not generally viewed to...

Implications of Technical and Legislative Harmonization for Integrated Coastal Zone Management in the Wider Caribbean Region
Sustainable development within the coastal areas of the wider Caribbean region will require government and non-government institutions alike to coordinate their activities, both nationally...

NOAA's Damage Assessment Program: Past, Present, and Future
This paper reviews trustee authorities established under the Super fund Act of 1980 and the Oil Pollution Act of 1990 to provide an introductory framework for more detailed presentations...

Dynamics of Mangrove Ecosystem along the Nigerian Coastline
The mangrove brackish water ecosystem along the Nigeria coastline is dominated by the Niger delta and the Astrand coastal area in the east covering an area of about 2003.49 km. Other areas...

Morphology and Current Dynamic of the Coast of Togo
The Togolese coast, flat and fifty km long, is made of two generations of beach ridges, separated from the sedimentary coastal basin, of the Tertiary age, by a continuous system of lagoons....
